Answer:

Option A

Step-by-step explanation:

<h3>Arithmetic sequence:</h3>

In a arithmetic sequence, difference between any two consecutive term is constant.

a₁ = 9 & d = 7

t₁ = 9

t₂ = a₁ + d

= 9 + 7

= 16

t₃ = t₂ + d = 16+ 7

= 23

t₄ = t₃ + d

= 23 + 7

= 30

t₅ = t₄ + d

= 30 + 7

= 37

9,16,23,30,37,.......

Answer:

40°

Step-by-step explanation:

As sum of angles of the triangle is 180°

therefore the third angle will be 180 -( 75 + 65)=40°

x=40°= vertically opposite angle

Y=-2x²-8x-5 domain and range

Jobisdone [24]

Answer:

Domain: All real numbers

Range: y≤3

Step-by-step explanation:

The given function is

$y = - 2 {x}^{2} - 8x - 5$

This is a polynomial function.

The domain is set of all values of x, that makes this function defined.

Since polynomial functions are defined everywhere, the domain is all real numbers.

To find the range we put the function in vertex form:

$y = - 2( {x}^{2} + 4x) - 5$

$y = - 2( {x}^{2} + 4x + 4) - 5 + - 4 \times - 2$

$y = - 2( {x} + 2)^{2} - 5 + 8$

$y = - 2( {x} + 2)^{2} + 3$

The maximum value is 3

The function turns downward, hence the range is:

$y \leqslant 3$

Answer:

Domain: all real values of x

Range: all real values of y

Translation depends on the parent function

If the first function was:

y = cuberoot(x)

Then translation is:

Vertical translation 1 unit downwards

45.6/109.2 = x/115<br><br> Is x, 48.02?

MAXImum [283]

Yes correct x is 48.02 here is why.

simplify 45.6/109.2 to 0.417582

multiply both sides by 115

simplify 0.417582 x 115 to 48.021978

switch sides

Answer: x = 48.021978
