Find the number that belongs in the green box. round your answer to the nearest tenth.

Delicious77 [7]

Answer:

4.6

Step-by-step explanation:

Use sine rule to find the number that belongs to the box.

Thus:

$\frac{a}{sin(A)} = \frac{b}{sin(B)}$

a = ?? (the number in the green box)

b = 5

A = 38°

B = 42°

Plug in the values

$\frac{a}{sin(38)} = \frac{5}{sin(42)}$

Multiply both sides by sin(38)

$\frac{a}{sin(38)} \times sin(38) = \frac{5}{sin(42)} \times sin(38)$

$a = \frac{5 \times sin(38)}{sin(42)}$

$a = 4.6$ (nearest tenth)

A store owner spends 7x + 13 dollars on two orders of boxes of light bulbs, including shipping.

Alex Ar [27]

Answer:

$B = 4x + 8$

A box = $11

Step-by-step explanation:

Given

$Total = 7x + 13$

Represent the first order with A and the second with B.

So, we have:

$A = 3x + 5$

Solving (a): Find B.

To find B, we make use of:

$A + B = Total$

Make B the subject

$B = Total - A$

Substitute values for Total and A

$B = 7x + 13 - (3x + 5)$

Open bracket

$B = 7x + 13 - 3x - 5$

Collect Like Terms

$B = 7x - 3x + 13 - 5$

$B = 4x + 8$

Solving (b): Cost of a box of light bulb

This means that:

$Total = 90$

Substitute 7x + 13 for Total

$7x + 13 = 90$

Collect Like Terms

$7x = 90 - 13$

$7x = 77$

Make x the subject

$x = \frac{77}{7}$

$x = 11$

Need help can someone help me pleaseeee

Hunter-Best [27]

at first we write each one as a sequence

and find its equation

the first table

-19, -11, -3, 5

8x-19

the third table

15,12,9,6

-3x+15

the second table

-1. 5,1.5,3,4.5

+3 +1.5 +1.5

so the third table is the nonlinear function
