If the figures below are similar with a scale factor<br> of 6:5, find the value of x.
xxMikexx [17]

Answer:

x = 33.6

Step-by-step explanation:

Formula to be used for the scale factor,

Scale factor = \frac{\text{Dimension of the big triangle}}{\text{Dimension of the small triangle}}

From the figure attached,

Side length of the big triangle = x

Corresponding side length of small triangle = 28

Scale factor = \frac{6}{5}

\frac{6}{5}=\frac{x}{28}

x = \frac{6\times 28}{5}

x = 33.6

Jennifer's grandma bought her a $50 savings bond when she was born. When Jennifer is 30 years old, the bond will have earned 110
Digiron [165]

Answer:

105$

Step-by-step explanation:

We are told that she starts with 50$

We are also that after 30 years she earns 110% on interest

Given this information we need to find the value of the bond after the 30 years

To do so we take 110% of the initial value (50$) and add that to the initial value

So the answer = 110%(50) + 50

110%*50=55

55+50=105

So in 30 years the bond will be worth 105$

F(x) = x2 + 2, g(x) = x2 - 1, h(x) = 3x<br> Evaluate.<br> g(h( f((-1))) =
Evgesh-ka [11]

The value of the composite function is g(h(f(-1)))=80

Step-by-step explanation:

In this problem we have the following functions:

f(x)=x^2+2\\g(x)=x^2-1\\h(x)=3x

We want to find the composite function

g(h(f(x)) and compute its value in x = -1.

In order to do that, we start by calculating the value of f(x) for x = -1:

f(-1)=(-1)^2+2=1+2=3

Now we compute h(f(x)) for x = -1:

h(f(-1))=3(f(-1))=3(3)=9

And now we compute g(h(f(x))) for x = -1:

g(h(f(-1)))= (h(f(-1))^2-1=9^2-1=80
