9 quarters, 7 dimes, & 5 nickels
A quarter is $0.25, a dime is $0.10, & a nickel is $0.05
So we just need to multiply the values & then add them up.
9 quarters is $2.25, 7 dimes is $0.70, & 5 nickels are $0.25
When you add them up, the total value of Jack's change is $3.20
He's really close, but Jack doesn't have enough money

9*25
225=$2.25
$2.25+7*10
295=$2.95
$2.95+5*5
$3.20

(intro) Slope is change in y divided by change in x (axes). Here, the y axis is depth and the x axis is hours. So, the slope is change in depth between any two points, divided by the change in hours between the same points. The slope of this line is half a foot depth divided by 2 hours.
a) So, the slope is 0.5 / 2 = 0.25, or 1/4.
b) The graph shows a constant rate of change because the line is straight (it increases at the same speed. If the line was curving, it would not be a constant rate of change).
c) Yes, because the line has a constant rate of change now.

Split up the interval [2, 5] into n equally spaced subintervals, then consider the value of f(x) at the right endpoint of each subinterval.

The length of the interval is 5-2=3, so the length of each subinterval would be \dfrac3n. This means the first rectangle's height would be taken to be x^2 when x=2+\dfrac3n, so that the height is \left(2+\dfrac3n\right)^2, and its base would have length \dfrac{3k}n. So the area under x^2 over the first subinterval is \left(2+\dfrac3n\right)^2\dfrac3n.

Continuing in this fashion, the area under x^2 over the kth subinterval is approximated by \left(2+\dfrac{3k}n\right)^2\dfrac{3k}n, and so the Riemann approximation to the definite integral is

\displaystyle\sum_{k=1}^n\left(2+\frac{3k}n\right)^2\frac{3k}n

and its value is given exactly by taking n\to\infty. So the answer is D (and the value of the integral is exactly 39).

The vertex form of the equation of a parabola is y=2(x+4)^2-7. What is the standard form of the equation.
Elan Coil [88]

Answer:


Step-by-step explanation:

To obtain the standard form of the equation of the parabola y=2(x+4)^2-7, first perform the indicated operations:

y = 2[x^2 + 8x + 16 - 7], or

y = 2[x^2 + 8x + 9],

or y = 2x^2 + 16x + 18

None of the given possible answers match.  The fourth one, D, is closest to the above result, differing only in the constant term (25 versus 18).
