If you would like to simplify (3x^2 - 2) * (5x^2 + 5x - 1), you can calculate this using the following steps:
(3x^2 - 2) * (5x^2 + 5x - 1) = 3x^2 * 5x^2 + 3x^2 * 5x - 3x^2 * 1 - 2 * 5x^2 - 2 * 5x + 2 * 1 = 15x^4 + 15x^3 - 3x^2 - 10x^2 - 10x + 2 = 15x^4 + 15x^3 - 13x^2<span> - 10x + 2
</span>
The correct result would be 15x^4 + 15x^3 - 13x^2<span> - 10x + 2.</span>
Answer:
2261,9 cm³
Step-by-step explanation:
First, you need to find the area of the base:
A=36
cm²
Now let's multiply it for the height:
36π cm² × 20 cm = 720π cm³
= 2261,9 cm³
The third answer (Dividing the area by the height, multiplying the quotient, etc) is correct.
If we multiply by the height, we receive an expression equal to the sum of the bases divided by two. Multiplying by two, we now have the sum of the bases. Subtracting one base gives the length of the other base.
Answer:84mph there and 42mph back
Step-by-step explanation:do 924 divided by 11 and 924 by 22
Thanks for the full problem. You did part A correctly but wrote "large shirt" instead of "red shirt" in the denominator. You correctly used 0.35, the probability of a red shirt.
The formula for conditional probability applied here says:
P( large | red ) = P(large & red) / P(red)
We have n=100 shirts, 5 of which are large and red
P(large & red) = 5/100
P(red) = 35/100
P(large | red) = (5/100)/(35/100) = 5/35 = 1/7 = 0.14285...
Part A answer: 14.3%
P(small | red) = P(small & red) / P(red) = (30/100)/(35/100)=6/7=.8571...
Part B answer: 85.7%
