Answers

Step-by-step explanation:

So visually youre given the function

for h(-4) it can also be written as h(-4) = y

what do you get for y when you substitute - 4 for x?

All you have to do is trace the line until you get to x=-4 and then find the y that corresponds to it (looks like around y= - 1)

for the other one h(x) = - 5

what do you get for x when you substitute - 5 for y?

what you do is similar, trace the line along the y-axis and see what x-value you get for y =-5

Answer:

3 and x = 0

Step-by-step explanation:

To find the value of h(- 4)

Locate x = - 4 on the x- axis, go vertically up to meet the graph at (- 4, 3 )

Then the value of h(- 4) = 3

For h(x) = - 5

Locate y = - 5 on the y- axis. This is the point (0, - 5)

then the value of x for which h(x) = - 5 is x = 0

Answer:

Answer:

BHM = 64°

x = 16°

Step-by-step explanation:

BHL is 90° and MLH is 26°. This means to find BHM, we have to subtract 26 from 90.

90 - 26 = 64°

BHM = 64°

BHM is also equal to 4x.

So, to find x, divide 64 by 4.  (64 = 4x  -->  64 ÷ 4 = x)

64 ÷ 4 = 16

x = 16°

Tom is tiling a wall.
He needs to buy at least 100 tiles. The tiles are sold in large packs and small packs.

Large pack = 40 tiles £18
Small pack = 28 tiles £14

Special offer = 25% reduction when you buy 3 or more large packs.

Work out the cheapest cost for Tom to buy the packs of tiles he needs.

Answer £

Answers

Answer:

The correct answer is - £ 40.5 for 3 large packs.

Step-by-step explanation:

Given:

Large pack = 40 tiles £18

Small pack = 28 tiles £14

Special offer = 25% reduction when you buy 3 or more large packs.

Solution:

Following combinations are possible for tom to get the tiles he needs:

1. 3 large packs

40*3 = 120 tiles with 25% discount

cost = 18*3 - 0.25*18*3 = 40.5

2. 4 small packs

28*4 = 112 tiles

cost = 14*4 = 56

3. 2 large packs and 1 small pack

40*2 + 28 = 108 tiles

cost = 18*2 + 14 = 50

4. 1 large pack and 3 small packs

40 + 28*3 = 124 tiles

cost = 18 + 14*3 = 60

Thus, the correct answer is - 1st case with three large packs.

The different kinds of beads Jen is using to make purses come in packages of 4 and 12. What is the least number of each kind of bead Jen can buy to have an equal number of each of the different kinds of​ beads?

Answers

Answer:

You should buy 3 packages of beads that come in packages of 4 and 1 package of beads that come in packages of 12 to have an equal number of each of the different kinds of beads.

Step-by-step explanation:

Since the different kinds of beads Jen is using to make purses come in packages of 4 and 12, to determine what is the least number of each kind of bead Jen can buy to have an equal number of each of the different kinds of beads the following calculation must be performed:

12/4 = 3

4 x 3 = 12

Thus, you should buy 3 packages of beads that come in packages of 4 and 1 package of beads that come in packages of 12 to have an equal number of each of the different kinds of beads.

1. tan(x) = 9/20

arctan(9/20) ≈ 24.23°

2. cos(x) = 17/32

arccos(17/32) ≈ 57.91°

3. tan(x) = 13/18

arctan ≈ 35.84°

4. sin(x) = 21/28

arcsin(21/28) ≈ 48.59°

Answer:

1    x = 24.2°

2    x = 57.9°

Step-by-step explanation:

You must memorize the definitions of the trig functions and then these problems are easy

1:   tan = opposite side/adjacent side

opp side to x is 9 and adjacent side is 20

So, tan x = 9/20

x = arctan (9/20) = 24.2°

2:   cos = adjacent side/hypotenuse

adjacent side = 17 and hypotenuse = 32

cos x = 17/32

x = arccos (17/32)

x = 57.9°

You do 3 and 4.  Hint:  Use the tan function in 3 and the sine function in 4

answer:

∠B = 70°

step-by-step explanation:

as you can see, the angle are alternate exterior anglestherefore, they are EQUALwe can set them equal to each and solve for x first

∠A = ∠B

8x + 6 = 4x + 38

4x + 6 = 38

4x = 32

x = 8

now, we will plug in x in the expression for B to find B

4(8) + 38

32 + 38

= 70

therefore, ∠B = 70° and x = 8

What is the cost of his journey?
Show your working

Answers

Answer:

Step-by-step explanation:

First, find the cost from traveling 12.2 miles. Since the cost is £1.50 per mile, multiply 12.2 by 1.5:

12.2(1.5)

= 18.3

Add the standing charge to this:

18.3 + 5

= 23.3

So, the cost of his journey is £23.30
