Area of a triangle = 1/2 × base × height

Plug in what we know.

78 = 1/2 × b × 9¾

Multilply each side by 2 to get rid of the 1/2...

156 = b × 9¾

Write 9¾ as an improper fraction.
(9¾ = 9 + 3/4 = (9×4)/4 + 3/4 = 36/4 + 3/4 = 39/4)

156 = b × 39/4

Multiply each side by 4...

624 = b × 39

Divide each side by 39...

16 = b

Done! The length of the base of the triangle is <u>16</u> inches.

Here is the question 13. Higher Order Thinking In the equation 8x - the variable x represents the same value. Which value of x i
pav-90 [236]

Answer:

\begin{array}{ccccc}x & {0} & {1} & {2} & {3} \ \\ 8x & {0} & {8} & {16} & {24} \ \end{array}

Step-by-step explanation:

Given

8x

Required:

Solve for x = 0,1,2,3

For x = 0

8x = 8 * 0

8x = 0

For x = 1

8x = 8 *1

8x = 8

For x= 2

8x = 8 * 2

8x = 16

For x = 3

8x = 8 *3

8x = 24

Hence, the results are:

\begin{array}{ccccc}x & {0} & {1} & {2} & {3} \ \\ 8x & {0} & {8} & {16} & {24} \ \end{array}

People in Spaceland live in 8 space stations, and travel between the stations in tubes.Every pair of stations is connected by tw
NeTakaya

Based on the way these stations are connected, we can infer that there are <u>56 tubes. </u>

<h3>Number of tubes in Spaceland </h3>

Each pair of stations have 2 tubes. This means that every station is connected to each of the others.

We can therefore infer that each station has 7 tubes to the other stations.

The total number of tubes would therefore be:

= Number of stations x Number of tubes per station

= 8 x 7

= 56 tubes

In conclusion, there are 56 tubes.

I need help with this please I’ve done this question so many times and I keep on getting false answers
Mkey [24]

Answer:

a=-1 b=3 h=-4 k=5. Hope this helps.

Step-by-step explanation:

We need to find transformations from f(x) to g(x).

K is formula usually means vertical shift. Vertical shift are usually at right end of formula. f(x) has a vertical shift of zero, while g(x) vertical shift is 5. So our k is 5.

h represent our horizontal shift in a equation.

Our horizontal shift is opposite of the sign given.

F(x) has no hoeinzontal shift, while g(x) has x+4.

Set x+4=0

x + 4 = 0

x  =  - 4

so our h is -4.

B represent our horizontal compression or stretch.

Our horizontal compression/stretch is reciprocal of our b given.

f(x) has no compression or stretch, while g(x) has 1/3x.

Set 1/3x to one.

\frac{1}{3} x = 1

x = 3

so our b is 3.

A represents the vertical compression/ stretch. F(x) doesnt have one but G(x) does.

Since it has just a negative sign in front of it, the compression is -1 so a=-1
