You can focus on the two sub-triangles ABC and ACD

We know that they are both right triangles, because we're given that AC and BD are perpendicular.

The sides AB and AD are the hypothenuses of these triangles, so we know their length through the pythagorean theorem:

AD^2 = AC^2+CD^2

AB^2 = AC^2+BC^2

But since we're given BC=CD, the expressions for AD and AB are actually the same expression. This proves that AD=AB, and thus that the triangle is isosceles.

The graph of a function f is shown. Use the graph to estimate the average rate of change from x=-2 to x=0
Llana [10]

Answer:

2

Step-by-step explanation:

Given:

The interval, x = -2 to x = 0.

Required:

Average rate of change from x = -2 to x = 0.

SOLUTION:

From the graph,

If x = -2, f(-2) = 0.

If x = 0, f(0) = 4

Average rate of change = \frac{f(b) - f(a)}{b - a}

Where,

a = -2, f(a) = 0

b = 0, f(b) = 4

Plug in the values into the formula:

= \frac{4 - 0}{0 -(-2)}

= \frac{4}{2} = 2

Average rate of change from x = -2 to x = 0 is 2.

Look at the table of values below.
ivanzaharov [21]

Answer:

Your answer will be C. y= 4x-1

Step-by-step explanation:

On the x value side, the numbers represent what to fill in x with, and y should be the output of it.

For example :

4(1) = 4 - 1 = 3

4(2) = 8 - 1 = 7

4(3) = 12 -1 = 11

Hope this helps and was correct

The Roosevelts and the Jaspers live in the same city and pay the same sales
Nana76 [90]

Answer:

Yes, because the Jaspers paid a higher percentage of their income in sales tax than the Roosevelts did.

Step-by-step explanation:

Regressive tax is a constant, instead of a percentage of income. Those with a lower income would pay a higher percentage of their income. Both families, irregardless of income, paid $16,000 in taxes.

If f(x)=2x+3 and g(x)=x^2, then g[f(-3)]=?
Wittaler [7]
If f(x)=2x+3 and g(x)=x^2 then

f(g(x))=2x^2+3 then:

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

f(g(-3))=2*9+3

f(g(-3))=18+3

f(g(-3))=21
