G(t)=2+5<br>f(t) = -1² + 5<br>Find (8 + f)(t)

jolli1 [7]

Answer:

Step-by-step explanation:

Given that,

G(t) = 2+5

F(t) = -1^2 + 5

= (-1 x -1) = 1

Therefore, F(t) = 1 + 5

G(t)= 7

Substitute 7 for(t)

F(7) =1+5

To find (8+f)(t)

Substitute all for t

(8+6)x7

=(14)x7

=98

What is the surface area of the pyramid shown to the nearest whole number? the diagram is not drawn to scale

Citrus2011 [14]

Answer:

(B) $SA=72{\tex{feet^2}$

Step-by-step explanation:

Given: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.

To find: The Surface are of Pyramid.

Solution: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.

Now, surface area of the Pyramid is given as:

$SA={\text{Area of base}+\frac{1}{2}pl$

where p is the perimeter and l is the slant height.

Now, area of base is given as:

$A=4(4){\tex{ft^2}$

$A=16{\tex{ft^2}$

And, the surface area is given as:

$SA=16+\frac{1}{2}(4)(4)(7)$

$SA=16+56$

$SA=72{\tex{feet^2}$

Hence, option B is correct.
