Answer:
Option A, πr^2h
Step-by-step explanation:
V=πr^2h
Answer: Option A, πr^2h
Answer:
a = 3
Step-by-step explanation:
Factorize (x+5)(x-4)(x+2)
(x+5)(x-4)(x+2)
= (x²-4x+5x-20)(x+2)
= (x²+x-20)(x+2)
= (x³+2x²+x²+2x-20x-40)
= x³+3x²-18x -40
Compare with x^3+ax^2
3x² = ax²
3 = a
Rearrange
a = 3
Hence the value of a that makes the expressions identical is 3
Answer:
- 50
Step-by-step explanation:
x = 3
f ( x ) = - 4x^2 - 3x - 5
f ( 3 )
= - 4 ( 3 )^2 - 3 ( 3 ) - 5
= - 4 ( 9 ) - 3 ( 3 ) - 5
= - 36 - 9 - 5
= - 50
Answer:
4410 cards, 9 albums
Step-by-step explanation:
Number of cards in a box = 315
Number of boxes = 14
b) Total number of cards = Number of boxes × Number of cards in 1 box
=
a) Carmella estimated she had 3,000 cards so she bought a 6 album of 500 cards.
No, 6 albums are not enough as she estimated wrong number of cards. There are total of 4410 cards but she estimated it to be 3000 cards.
c) Total number of albums required = 

Thus, she will require 9 albums to put all her cards.
<h2>Answer:</h2><h3><em>
y = -1x - 9</em></h3><h2>Explanation:</h2>
First, we’ll need to find the <u>slope</u>.
(-5,-4) (-2,-7)
m =
m = 
m =
m = -1
Next, substitute these values into the <u>point slope equation:</u>
y -
= m(x -
)
y - (-7) = -1(x - (-2))
y + 7 = -1(x + 2)
Now, convert to <u>slope intercept form (y = mx + b):</u>
y + 7 = -1x -2
-7 -7
y = -1x - 9
