Answer:

f(2) = 36

Step-by-step explanation:

Put 2 where x is and do the arithmetic.

f(2) = 6^2

An exponent of 2 means 6 is a factor two times.

f(2) = 6×6

f(2) = 36

Answer:

Step-by-step explanation:

To evaluate f(x) = 6^x at x = 2, substitute 2 for x:

f(2) = 6^2 = 36

Find the number of years it would take for $1200 to earn simple interest of $324 at an annual interest rate of 6% per year

topjm [15]

ANSWER

It would take 45 good years

EXPLANATION

We calculate simple interest using the formula,

$I=\frac{P\times T\times R}{100}$

From the question,

$I=324$ dollars

$R=6$ %

and

$P=120$ dollars

We substitute into the above formula

$324=\frac{120\times T\times 6}{100}$

$324=\frac{720\times T}{100}$

$324\times100=720\times T$

$\frac{324\times100}{720}=T$

$\frac{324\times10}{72}=T$

$45=T$

Therefore it would take 45 years.

Jackson says has an odd number of model cars.he has 6 cars on one shel and 8 cars on another shelf.is jackson correct?explain

grigory [225]

No. It's rather simple, down to addition. Ask yourself, what does 6 + 8 equal? 6 + 8 = 14. Now is this an odd number? No, 14 is an even number.

I hope this helps! If not I'm sorry.

Find the values of x and y.

Elis [28]

Answer:

Option A

x=6 , y=9

Step-by-step explanation:

As we can see in the figure that point T is the mid point of rectangle and there are two diagonals QS and PR

So in basic geometry we know that the length of the diagonal from the mid point i.e. Taking the diagonal QS the length of QT and TS would be equal because they are same diagonal which is cut into two parts by point T

Similarly the Length of RT and the length of TP would be same

From all this we deduct that

3x = 2y ..................(i)

and

y + 3 = 2x ................(ii)

From equation (i)

3x = 2y

Dividing both sides by 3 the equation becomes

x= $\frac{2y}{3}$ ....................(iii)

Putting this value in equation (ii)

y + 3 = 2( $\frac{2y}{3}$ )

y+3 = $\frac{4y}{3}$

multiplying both sides by 3

3(y+3)= $\frac{4y*3}{3}$

the equation becomes

3y+9=4y

subtracting 3y from both sides

3y-3y+9=4y-3y

y=9

Putting the value of y in equation (iii)

x= $\frac{2*9}{3}$

solving it

x= $\frac{18}{3}$

x=6

so x=6 and y=9 is answer which is option A

Find the x-intercepts if the parabola with vertex (-3,-18) and y-intercept (0,0). Write your answer

anzhelika [568]

Vertex form is
y = a(x - b)^2 + c

here a = -3 and b = -18 so we have

y = a(x + 3)^2 - 18

when x = 0 , y= 0 ( the y-intercept) so:-

0 = a(3^)2 - 18
9a = 18
a = 2

so the parabola is y = 2(x + 3)^2 - 18

x intercepts found as follows:-

2(x + 3)^2 - 18 = 0
(x + 3)^2 = 9
x + 3 = +/- sqrt9 = +/- 3

so x intercepts are 0 and -6 Answer
