Which graph represents the function f(x)= 0.2^x + 3
Dennis_Churaev [7]

The third graph or bottom left graph represents f(x) = 0.2^{x} + 3.

Step-by-step explanation:

Step 1:

To determine which of the given graphs represents the equation f(x) = 0.2^{x} + 3, we substitute some values in the place of x.

When x=0, f(x) = 0.2^{x} + 3, f(0) = 0.2^{0} + 3= 4.

Anything with an exponent of 0 will equal 1.

So the graphs on the right side cannot be the answers.

Step 2:

Now we substitute another value to determine which graph represents f(x) = 0.2^{x} + 3.

When x=1, f(x) = 0.2^{x} + 3, f(1) = 0.2^{1} + 3= 4.2.

The value of f(x) when x=1 is lesser than the value of f(x) when x =0.

So the third graph or bottom left graph represents f(x) = 0.2^{x} + 3.

Which polynomial is a perfect square trinomial? (4 points) 9x2 − 12x + 4 36b2 − 24b + 16 16x2 − 24x − 9 4a2 − 10a − 25ynomial is
o-na [289]

Answer:

9x² − 12x + 4

Step-by-step explanation:

A perfect square trinomial:

a² + 2ab +b²= (a + b)²

a² - 2ab +b²= (a - b)²

9x² − 12x + 4 = (3x)² - 2*(3x)*2 + 2² = (3x - 2)²

36b² − 24b + 16

16x² − 24x − 9

4a² − 10a − 25

Write an equation to show the height of the two buildings are equal to each other. Then solve for x. Show all your steps when so
Ierofanga [76]

Answer:

X = 108.

Step-by-step explanation:

Heights are equal, So equation will be,

4 + 3 \sqrt{x - 8}  = 34

So, solving the eq.

Subtract 4 from both sides ,

3 \sqrt{x - 8}  = 30

Divide 3 to both sides,

\sqrt{x - 8}  = 10

Squaring both sides,

x - 8 = 100

Add 8 to both sides,

x = 108
