Answers

Answer 1

Answer:

hello there...

you know BODMAS for sure

First brackets then of then divi then multi then add and then subtract

going by BODMAS

we need to first of all multiply of -6 and 3

hence ans is multiplying -6 and 3

( option 1 Is wrong by the equation u sent if the equation is correct then ans is which given bur by options I think equation is wrong becoz I don't see divide symbol)

A {(2, 1), (5,3), (6, 7), (7, 11)}
B ((2.-1), (5,3), (8, 7). (11.11 )}
C {(2, -1), (5,5), (8,7), (11, 11 )}
D (5.-1), (5,5), (8,7), (11, 11)}

Answers

Answer:

B ((2.-1), (5,3), (8, 7). (11.11 )}

Step-by-step explanation:

Linear function:

The rate of change is always the same.

Item a:

x = 2 to x = 5 -> y = 1 to y = 3. Rate of change of 2/3.

x = 5 to x = 6 -> y = 3 to y = 7. Rate of change of 4.

Different rates of change, so not linear.

Item b:

We can look that for each point, when x changes by 3, y changes by 4, so the rate of change is the same and this set of points represents a linear function, and the answer is option b.

Find x.
a. 40.3
b. 37.2
c. 17.3
d. 19.1

Answers

Answer:

x = 17.3

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hyp

sin 25 = x /41

41 sin 25 = x

17.32734=x

Rounding to the tenths place

x = 17.3

We have to find,

The required value of x.

Now we can,

Use the trigonometric functions.

→ Sin(θ) = opp/hyp

Let's find the required value of x,

→ Sin (θ) = opp/hyp

→ Sin (25) = x/41

→ x = 41 × Sin (25)

→ x = 41 × 0.42262

→ x = 17.32734

→ [x = 17.3]

Hence, option (c) is the solution.

Answer:

AB= 2√137 cm

Step-by-step explanation:

because we have a right triangle we apply the Pythagorean theorem

hypothenuse² = side² + side²

AB² = BC² + AC², substitute the given sides BC=8 and AC=22

AB² = 8² + 22² , square the numbers and apply the square root to both side

AB = √(64 + 484), add the numbers

AB = √548, simplify the square root

AB= 2√137 cm

Mr Brown spends 65% of his monthly income and saves the rest. After being promoted, his salary increases by 40% and his expenses increase by 20%. Find the percentage change in his savings.

Answers

Answer:

There is a percentage increase of 77.1% in savings

Step-by-step explanation:

The answer can be determined by assigning a value to the income of Mr Brown.

Let Mr. Brown's initial income = 100

Percentage spent = 65%

Amount spent = 100 x 0.65 = 65

Percentage he saves = 100 - 65% = 35%

Amount he saves = 100 x 0.35 = 35

Salary after increase = 1.40 x 100 = 140

Increase in expenses = 1.2 x 65 = 78

Amount saved after increase in income = 140 - 78 = 62

Percentage increase = (new amount saved / previous amount saved) - 1

Percentage increase = (62 / 35) - 1 = 0.771 = 77.1%

What is subtraction?

To subtract in mathematics is to take something away from a group or a number of objects.

In another meaning subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

The group's total number of items decreases or becomes lower when we subtract from it.

Given that sell of CDs in 1993 is 2.3 × 10⁶.

Sell of CDs in 2001 is 7.9 × 10⁷.

The difference between sell is = 7.9 × 10⁷ - 2.3 × 10⁶

76.7 × 10⁵ hence it will the correct option.

Given:

Miguel needs to cut a board that is Two-thirds of a yard long into 3 equal pieces.

To find:

The expressions that can you use to find the length of each piece.

Solution:

It is given that Miguel needs to cut a board that is Two-thirds of a yard long into 3 equal pieces. It means [tex]\dfrac{2}{3}[/tex] is divided in 3 equal parts.

[tex]\dfrac{2}{3}\div 3[/tex]

It can be written as:

[tex]\dfrac{2}{3}\div 3=\dfrac{2}{3}\times \dfrac{1}{3}[/tex]

[tex]\dfrac{2}{3}\div 3=\dfrac{2}{9}[/tex]

Therefore, the required expression is [tex]\dfrac{2}{3}\div 3[/tex] and the length of each piece is [tex]\dfrac{2}{9}[/tex] yards.

Find the size of one interior angle of a regular 10-sided polygon.

Answers

Answer:

144

Step-by-step explanation:

Exterior angle = [tex]\frac{360}{number \ of \ sides}[/tex]

                       [tex]=\frac{360}{10}[/tex]

                       = 36

Interior angle and exterior angles are supplementary.

interior angle + exterior angle = 180

Interior angle + 36 = 180

Interior angle = 180 - 36

                       = 144

Which statement about the function is true? The domain of the function is all real numbers less than or equal to −2. The domain of the function is all real numbers less than or equal to 9. The range of the function is all real numbers less than or equal to −2. The range of the function is all real numbers less than or equal to 9.

Answers

Answer:

"The range of the function is all real numbers less than or equal to 9."

Step-by-step explanation:

For this question the domain is (-∞,∞)

The range is all numbers less than 9 (the y-coordinate of the vertex)

The reason the numbers are less than 9 is because the graph is concave down (aka it looks like a frowny face)

Therefore the answer is "The range of the function is all real numbers less than or equal to 9."

The particular value of x represents the solution that shows the value of the x-intercept

for example

In a case of a quadratic equation where we have

Then we can have

(x-a) = 0 or ((x-b) = 0

Then we have x = a or x = b
