Answer:

1920 cubic centimeters

Step-by-step explanation:

If you recall the formula to find volume, it is V=Bh (Bh stands for area of the base times the height). First, multiply 14, 8, and 10 together, to get 1120, the volume of the first figure. To find the volume of the second figure, do the same: multiply 10, 10, and 8 together to get 800. Finally, add the two volumes together to get the volume of the figure, 1920 cubic centimeters.

which is greater? -1 17/20 or -1 8/10PLSSS HELP ASAPplsss show work aswell

Answers

-1 17/20 and -1 8/10 can be compared easily if we give them common denominators. If we multiply the second fraction by 2, both fractions will have a denominator of 20.

8 * 2 = 16
10 * 2 = 20
New fraction: 16/20

-1 17/20 vs. - 1 16/20

-1 16/20 (-1 8/10) is greater. (For negative numbers, you can tell which one is greater by determining which one is closest to zero.)

Step-by-step explanation:

the average rate of change of a function f in an interval [x-low, x-high] is

(f(x-high) - f(x-low)) / (x-high - x-low)

the year 2000 means t = 2000-1980 = 20

the year 2015 means t = 2015-1980 = 35

so, we have

(A(35) - A(20)) / (35 - 20)

((-0.6(35)² + 37.2×35 + 243) - (-0.6(20)² + 37.2×20 + 243)) / 15

((-735 + 1302 + 243) - (-240 + 744 + 243)) / 15

(810 - 747) / 15 = 63/15 = 4.2

the average change rate between 2000 and 2015 is 4.2.

that means that the use of nuclear energy in the USA increased by 4.2 billions of kilowatt hours per year during that period.

jacket is on sale at 15% off the original price of $68. based on this sale how much money will he save

Answers

Answer: He will save $57.80

Step-by-step explanation: Sale Price = $57.8. This means the cost of the item to you is $57.8. You will pay $57.8 for an item with original price of $68 when discounted 15%. In this example, if you buy an item at $68 with 15% discount, you will pay 68 - 10.2 = 57.8 dollars.

A) 1/4

B) 1/3

C) 3/4

D) 1/2

(1/4) * 100 = 25 %

(1/3) * 100  = 33.33 %

(3/4) * 100 = 75 %

(1/2) * 100 = 50 %

5a x 3a = 15a^2 bc a times a makes it squared.

next, 5a x -1 = -5a

-5a -12a (bc they're like terms) = -17a

Find the vertex of a quadratic function written in standard form.
f(x) = 3x2 + 18x + 32
PLS HELP!!

Answers

Answer:

our vertex for f(x) = 3x² + 18x + 32 = (-3, 5 )

Step-by-step explanation:

let me write the standard form of a quadratic equation

[tex]a {x}^{2} + bx + c[/tex]

Now let me rewrite the original equation

[tex]3 {x}^{2} + 18x + 32[/tex]

Now we use this simple formula to find the vertex (h, k)

[tex]x = h = - \frac{b}{2a} \\ = - \frac{18}{2(3)} = - \frac{18}{6} = - 3 \\ h = - 3[/tex]

substitute -3 for x back into our original equation to solve for y our k value of our vertex

[tex]y = 3 ({ - 3})^{2} + 18( - 3) + 32 \\ = 3(9) - 54 + 32 \\ = 27 + 32 - 54 \\ = 59 - 54 \\ k = 5[/tex]

our vertex for f(x) = 3x² + 18x + 32 = (-3, 5 )
