Answer:

f(7) = 158

Step-by-step explanation:

To evaluate f(7) substitute t = 7 into f(t)

f(7) = 3(7)² + 11 = (3 × 49) + 11 = 147 + 11 = 158

Answer: f(7) = 158

Step-by-step explanation:

f(t)=3t^2+11 find f(7)...... this can be gotten by inputting the function of 't' into the given equation i.e.

f(t) = f(7)

t = 7, so therefore

f(7) = 3t² + 11

f(t) = 3(7)² + 11

    = 3(49) + 11

    = 147 + 11

f(7) = 158

So it is an isosceles triangle that means that the bottom two angles are equal...
so 
40 = 5x 
divide both sides by 5 and you get 8

now the triangle angles add up to 180
we make an equation out of it...
(2y + 20 ) + ( 5(8)) + 40 = 180
2y + 20 + 40 + 40 = 180
combine like terms
2y + 100 = 180
so subtract 100 from both sides
2y = 80
divide by 2 to isolate the variable
y = 40

You are correct!!! :)

100 POINTS FOR BRAINLIEST! according to the image, whats the answer? Answer wisely for the full 100
lesantik [10]

Answer:

Step-by-step explanation:

To find the area of a semicircle the formula is

\frac{\pi r^2}{2} \\=\frac{\pi 1^2}{2} \\=6.283m^2

The square

A=a^2=2^2=4m^2\\6.283+4=10.283m^2

A=wl=7*9=63m^2 (rectangle)

A=\frac{ab}{2} =\frac{6*4.5}{2} =13.5m^2\\63+13.5=76.5m^2 (triangle)

Graph this following function
Inessa05 [86]

Answer:

Please find attached the graph of the following function;

\left\{\begin{matrix}x - 1 & if & -2 \leq x < 0\\ 1 & if  & x = 0 \\ 3 & if & 0 < x \leq 2\end{matrix}\right.

Step-by-step explanation:

We note that the function is linear from x = 2 to just before x = 0

The linear relationship of the function f(x) with x changes just before x = 0

At x = 0, the value of f(x) is indicated as 1

From just after x = 0, the function is a straight horizontal line y = 3

The function also changes value immediately after x = 0 to the line y = 3

The areas where the function is defined are shown in continuous lines
