Phantasy [73]3 years ago

Answer:  The required values are

f(-2) = 120, f(0) = 64  and  f(1) = 84.

Step-by-step explanation:  We are given the following function f(x) :

f(x)=16x^2+4x+64~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We are to find the values of the following :

(a)~f(-2),\\\\(b)~f(0),\\\\(c)~f(1).

To find the values of the function at the given points, we need to substitute the corresponding values of x in equation (i).

Substituting x = -2 in equation (i), we get

f(-2)=16\times(-2)^2+4\times(-2)+64=64-8+64=120.

Substituting x = 0 in equation (i), we get

f(0)=16\times0^2+4\times0+64=0+0+64=64.

Substituting x = 1 in equation (i), we get

f(1)=16\times1^2+4\times1+64=16+4+64=84.

Thus, the required values are

f(-2) = 120, f(0) = 64  and  f(1) = 84.

A cylindrical can of baked beans has a diameter of 8 cm and a height of 9 cm.
strojnjashka [21]
Formula for volue of cylinder is area time height. Lets find area
A=\pi r^2
diameter=2r
8=2r
r=4
Now substitute r to A= \pi r^2
A=\pi 4^2= 16\pi
Now we have formula
V=16 \pi *height=16 \pi *9=144 \pi - its the result, so B

You were born, your mother deposited 2000 in an account that pays 5% simple interest. How much would the balance be in your acco
leonid [27]

Answer:

C

Step-by-step explanation:

the formula for simple interest is given as A=P(1+rt), where A is the final balance, P is the initial principal balance (the amount of money that you start out with), r is the annual interest rate, and t is the time

we know that the mom deposited 2000 into an account when the person was born. This is our initial principal balance (the amount of money started out with)

substitute that value into the formula to get:

A=2000(1+rt)

we also know the rate, which is 5% and the time, which is 18

5%=0.05 (we need it as a decimal)

so substituting the values into the equation:

A=2000(1+0.05*18)

A=2000(1+0.9)

A=2000(1.9)

A=3,800

therefore the answer is C

Hope this helps!
