Answers

Answer 1

Answer:

8 units.

Step-by-step explanation:

To find the y-intercept for the first equation: f(x)=2x²-4x+6, we can simply plug in '0' as 'x' to represent the y-intercept:

f(x)= 2(0)²-4(0)+6 ---> f(x)= 6

Therefore, the y-intercept of the first equation is (0,6).

-------------------------------------------------------------------------------

In the table, we can see that when x=0, y=-2. This is our y-intercept for the table.

When we find the difference between the two, we get:

6-(-2)= 8.

A cow can give 5 gallons of milk if it eats 2 pounds of grass. Express x in terms of y, where y is the number of gallons of milk the cow gives, and x is the number of pounds of grass it eats.

Answers

Answer:y=2.5 x

Step-by-step explanation:

Given

Cow give 5 gallon of milk if it eats 2 pound of grass

i.e. it gives 2.5 gallon of milk if it eats 1 pound of grass

So we can say cow given 2.5 times of milk in gallon for each pound it eats

If cow eats x pounds of grass then it must yield 2.5 times of milk

Suppose milk is denoted by y  

therefore we can write

y=2.5 x

Therefore y=2.5 x represent the relation between grass and milk produced

A cone is cut by a plane parallel to its base. The small cone on top is similar to the large cone, with a similarity ratio of 1 : 2. The ratio between the volume of the small cone to that of the frustum is _ : _.

Answers

Answer:

1:1

Step-by-step explanation:

The ratio between the volume of the small cone to that of the frustum is 1:1.

Notice that the bigger cone is double than the smaller cone, which means the smaller cone is half of the volume of the bigger cone, if you wipe the small one, you would have the frustum with the same volume as the wiped part, because if you delete the smaller cone, you would be deleting half volume of the bigger cone, giving at the end a relation 1 : 1 between the frustum and the smaller cone.

If 99 people have a mean incame of doolar 400, how much is the mean incame increased by the addition of a woman with an incame of doolar 1500​

Answers

The new mean will be (400*99+1500)/100=411
The mean increased by 11.

Answer:

Step-by-step explanation:

Mean income of 99 people = $ 400

Sum of income of 99 people = 400 * 99 = $ 39600

Income of a woman = $ 1500

Income of 100 people = 39600 + 1500 = $41100

Mean of 100 people = 41100/100 = $411

411 - 400 = $11

Mean income increases by $11

The sum of two numbers is 198. If one number is 20% larger than the other number, what are the numbers?

Answers

x + y = 198

y = 1.20 x

x + 1.2 x = 198

2.2x = 198

x = 198/2.2 = 90

y = 198 - 90 = 108

Answer: 90 and 108

Answer:

108 and 90

Step-by-step explanation:

let the two numbers be x and y

from the question let y be the greater number

therefore, y = 20%x +x

y=20/100x + x

y=(20x+100x)/100

y=120x/100

y=1.2x

from the question

x+y=198______(1)

x+1.2x=198

2.2x=198

x=198/2.2

x=90

from (1)

x+y=198

90+y=198

y=108

x=90 y=108

Two​ fire-lookout stations are 14 miles ​apart, with station B directly east of station A. Both stations spot a fire. The bearing of the fire from station A is Upper N 35 degrees E and the bearing of the fire from station B is N 30 degrees W. How​ far, to the nearest tenth of a​ mile, is the fire from each lookout​ station?

Answers

The fire is a distance of 9.33 miles from Station A and 4.67 miles from Station B.

Let's denote the distance of the fire from station A as "x" and the distance of the fire from station B as "y".

From station A, the bearing of the fire is N 35° E. This means that if we draw a line connecting station A and the fire, the angle between this line and the north direction is 35°.

Similarly, from station B, the bearing of the fire is N 30° W. This means that the angle between the line connecting station B and the fire and the north direction is 30°.

Now, let's construct a triangle with vertices at Station A, station B, and the fire. The line connecting station A and station B represents the base of the triangle, and the lines connecting station A and the fire and station B and the fire represent the two sides of the triangle.

Since the triangle is isosceles (both sides are equal), the angles opposite the two sides will also be equal.

Let's denote the angle opposite side x as α and the angle opposite side y as β.

From the given bearings, we can determine the values of α and β:

α = 180° - 35° = 145°

β = 180° - 30° = 150°

Now, using the Law of Sines, we can set up the following ratios:

sin(α) / x = sin(β) / y

Solving for y, we get:

y = (sin(β) / sin(α)) * x

Substituting the known values, we have:

y = (sin(150°) / sin(145°)) * x

Using a calculator, we can evaluate the sin(150°) and sin(145°) to get:

y = (0.5 / 0.996) * x

y = 0.501 * x

Since the two stations are 14 miles apart, we know that x + y = 14.

Substituting the value of y from the previous equation, we have:

x + 0.501 * x = 14

1.501 * x = 14

x = 14 / 1.501

x ≈ 9.33

Now, to find the value of y, we can substitute the value of x into the equation:

y = 0.501 * x

y = 0.501 * 9.33

y ≈ 4.67

Therefore, the fire is 9.33 miles from Station A and 4.67 miles from Station B.

The fire is approximately 38.7 miles away from station A and 38.4 miles away from station B.

To solve this problem, we can use trigonometry and create a diagram to visualize the situation.

Now, let's label the diagram. We'll use the following labels:

A: Fire-lookout station A

B: Fire-lookout station B

F: Fire's location

Next, we need to determine the angles and distances involved. From the problem statement, we know the bearing of the fire from station A is N 35° E, and the bearing of the fire from station B is N 30° W. Let's mark these angles on the diagram.

To find the distance of the fire from each station, we can consider the angles formed between the stations and the fire. The sum of these angles should be 180° since we have a straight line. Let's find the missing angles by subtracting the given angles from 180°.

For station A:

Angle A = 180° - 35° = 145°

For station B:

Angle B = 180° - 30° = 150°

Now, let's draw lines from each station to the fire, and label the distances as dA and dB.

We can use trigonometry (specifically, the tangent function) to find the distances dA and dB. Tangent of an angle is equal to the opposite side divided by the adjacent side.

For station A:

tan(145°) = opposite side (dA) / adjacent side (14 miles)

dA = 14 * tan(145°)

For station B:

tan(150°) = opposite side (dB) / adjacent side (14 miles)

dB = 14 * tan(150°)

Now, let's calculate these distances using a calculator.

dA = 14 * tan(145°) ≈ 38.7 miles

dB = 14 * tan(150°) ≈ 38.4 miles

A police department used a radar gun to measure the speed of a sample of cars on the highway. Assume that the distribution of speeds is approximately Normal with a mean of 71 mph and a standard deviation of 8 mph. Using this distribution what is the z-score of a 65-mph speed limit?

Answers

Answer:

The z-score of a 65-mph speed limit is -0.75

Step-by-step explanation:

Here, we want to calculate the z-score

To calculate the z-score, we make use of the z-score formula

Mathematically;

z-score =(x-mean)/SD

from the question we identify the values as x = 65 mph, mean = 71 mph, Standard deviation(SD) = 8 mph

Plugging these values into the equation above, we have

z-score = (65-71)/8 = -6/8 = -0.75

Grace hit 12 balls in the batting cage out of 20 pitches. Tomorrow she is going to go to the same batting cage and get 30 pitches.
Use experimental probability to predict how many of the 30 pitches she will hit.

Answers

Answer:

she is expected to hit 18 out of the 30 pitches

Step-by-step explanation:

In this question, we are required to use experimental probability to make a prediction.

From the hits she has today, we can estimate the number of hits she might be getting tomorrow.

Since she made 12 hits out of 20 today, the probability that she has a hit will be 12/20 = 3/5

Now if she is having 30 pitches tomorrow, the expected number of hits would be the probability of getting a hit multiplied by the total number of pitches.

That would be 3/5 * 30 = 18 pitches

The perimeter of quadrilateral ABCD is 640. The perimeter of quadrilateral LMNO is 144. What is LM

Answers

Answer:

LM = 36

Step-by-step explanation:

A quadrilateral is a shape with 4sides. There are different type of quadrilateral such as square, rectangle, trapezium, parallelogram, kite and rhombus.

Perimeter of a quadrilateral is the addition of all 4 sides.

Since the shape is not specified neither is there a diagram, let's assume the quadrilateral is a square.

See attachment for diagram used in solving the question.

Perimeter of square = length+ length+ length+ length

= 4× length

Perimeter of quadrilateral ABCD:

640 = 4×length

Length = 640/4

Length = 160

Perimeter of quadrilateral LMNO:

144 = addition of all 4 lengths

144 = LM + MN + NO +OL

Since we are considering a square all the sides are equal.

LM = MN = NO = OL

144 = 4×LM

LM = 144/4

LM = 36
