a.) the maximum is just the vertex

-35/(2*-4.9)= it takes 3.5714 seconds to hit the maximum

which in height is

-4.9*3.5714^2+35*3.5714 +1= 63.5 metres

b.) for this just plug in 2

-4.9*2^2+35*2+1= 51.4 metres

c.) just plug in f(0) =1 meter

find the equation that passing through the point (4,6) and has a vertex of (2,-3)

Answers

Answer:

y = [tex]\frac{9}{4}[/tex] (x - 2)² - 3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (2, - 3 ) , then

y = a(x - 2)² - 3

To find a substitute (4, 6 ) into the equation

6 = a(4 - 2)² - 3 ( add 3 to both sides )

9 = a(2)² = 4a ( divide both sides by 4 )

[tex]\frac{9}{4}[/tex] = a

y = [tex]\frac{9}{4}[/tex] (x - 2)² - 3 ← in vertex form

Which inequality is represented by the graph?
y > -2/3x + 1
y < -2/3x + 1
y < -3/2x + 1
y > -3/2x+ 1

Answers

Answers

Answer:

Make me as brain liest plz

The perimeter of triangle DEF is; 30 cm

Similar Triangles

We are given dimensions of Triangle ABC as;

AB = 9 cmBC = 6 cmCA = 7.5 cm

Thus;

Perimeter of Triangle ABC = 9 + 6 + 7.5 = 22.5 cm

We are told that Triangle DEF is similar to Triangle ABC.

This means that the ratio of corresponding sides must be equal to the ratio of their perimeter.

Side EF corresponds to side BC. Thus;

Perimeter of Triangle DEF/22.5 = 8/6

Cross multiply to get;

Perimeter of Triangle DEF = (22.5 × 8)/6

Perimeter of Triangle DEF = 30 cm

The missing length of the given triangle divided into two right-angled triangle is 24.

The ratio 60:36:x is a ratio of 2:1:x. This means that the ratio of the lengths of the three segments is 2:1:x. The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.

Here is the solution in more detail:

The ratio 60:36:x can be written as 2:1:x.

This means that the ratio of the lengths of the three segments is 2:1:x.

The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.

Therefore, the missing length is 24.

Answer:

Cleo is: 25 years old

Range of their ages: 7 years

Step-by-step explanation:

Supposing that they are all around roughly the same age, say, Ahmed was 18 and Beth was 20. The mean/average, is taking both ages, and dividing it by how many people there were. Which was just two. So, 18+20=38. 38/2 gets you 19. To get Cleo's age, we would do,

18+20+ Cleo's age. to get a number, divide it by 3, and get 21. Saying that the mean/average is 21, he would definetly be older. So plug in ages. 24+20+18=62. 62/3 gets you 20.67. 25+20+18=63. 63/3 gets you 21. Therefore, he must be 25.

The range is calculated by subtracting the largest number, by the smallest number. And, given that the median, or, middle is 20, we can know that the previous answer is correct. 25-18 to get 7 as the range.

All the answers to the various operations given from question 1 to 6 have been explained and answered below.

1) We want to use order of operations to solve;

105 - 7² + (72 ÷ 9)

From order of operations which is BODMAS.

First operation for our given expression is bracket. Thus;

72 ÷ 9 = 8

Thus, we now have;

105 - 7² + 8

Next is addition;

7² + 8 = 57

Thus, we now have;

105 - 57 = 48

2)   884284

   - 349407

      534877

3) 6 ÷ ²/₇

⇒ 6 × ⁷/₂

21

4) Kevin makes $78.37 per day. Thus;

Amount he makes in 7 days = 78.37 × 7

$548.59

5) Product of 1389 and 6.58

⇒ 1389 × 6.58

9139.62

6) We want to use distributive property to express 27 + 60.

Now, in distributive property, it implies that;

a(b + c) = ab + ac

Thus, let us get the greatest common factor of 27 and 60 and factorize it out.

GCF of 27 and 60 is 3. Thus;

27 + 60 = ((3*9) + (3*20))

⇒ 3(9 + 20)

⇒ 3(29)

Last year, a gardening store ordered 530,570 potted plants. This year, they ordered 424,456 potted plants. What is the percent of decrease in the number of potted plants ordered annually?

Answers

Answer:

last year = 530570

this year = 424456

decreased plants = 530570-424456 = 106114

decreased percent = 106114÷530570×100%

= 20%

therefore 20% is the decrease precent in the number of potted plants ordered anually

Find the measures of the interior angles of the triangle.

Answers

Answer:

∠ A = 59°, ∠ B = 48° , ∠ C = 73°

Step-by-step explanation:

The interior angles of a triangle sum to 180°

sum the 3 angles and equate to 180

x + x - 11 + 73 = 180

2x + 62 = 180 ( subtract 62 from both sides )

2x = 118 ( divide both sides by 2 )

x = 59

Then

∠ A = x = 59°

∠ B = x - 11 = 59 - 11 = 48°

∠ C = 73°

Answer:

<A = 149*

<B = 138*

<C = 73*

Step-by-step explanation:

There are 360* total inside a triangle.

We subtract 73 from 360 to find the combined number of both angles a and b.

360-73 equals 287, so we know that both angles a and b add up to equal 287.

Since angle a equals x and angle b equals x - 11, we would combine the two expressions to find x. When we find x, it will allow us to know what both angles a and b equals to. So we combine x and x- 11, set it equal to 287, and solve for x.

x + x - 11 = 2x-11.

287 = 2x - 11

(Add eleven to both sides)

298 = 2x (divide both sides by two)

X = 149

Since angle a equals x, we know that angle a Is 149*.

And since angle b is x - 11, we take 149, subtract it by 11, and we get 138.

Answers

It would be graph A if I did it correct

Answer:

B) Graph B

Step-by-step explanation:

The quadratic equation in vertex form is represented by: y = a(x - h)² + k, where:

(h, k) = vertex

x = h : axis of symmetry

a = indicates a reflection in the x-axis; it also determines the graph's vertical stretch or shrink.

a > 0  the graph opens up.a < 0: the graph opens down.

h =  indicates a horizontal translation.

k =  indicates a vertical translation.

Given the given quadratic equation, y = (x - 2)² - 16:

The vertex occurs at point, (2, -16), and a = 1. Since the value of a is positive, then it implies that the graph opens upward, and the vertex is its minimum point.  The axis of symmetry occurs at h = 2.

To determine another point to use as a reference (and also for graphing) is solving for the equation's y-intercept, which is the point where it crosses the y-axis (where x = 0).

Y-intercept: set x = 0:

y = (x - 2)² - 16

y = (0 - 2)² - 16

y = (-2)² - 16

y = 4 - 16

y = -12

Therefore, the y-intercept is (0, -12).

Therefore, the graph that matches these given descriptions is Graph B.    

Attached is the graphed quadratic equation where it shows the vertex, y-intercept, and the axis of symmetry.
