Step-by-step explanation:
Answer:
a. π(9^2)(9) - (1/3)(9^2)(9)
step-by-step explanation:
we assume that container a is the whole cylinder, and that container b is the cylinder with the cone carved out.
the formula for the volume of a cylinder is
vcyl = πr²h
the formula for the volume of a cone is
vcon = (1/3)πr²h
here, we have r=h=9 in both cases, and we want to find the difference of volumes. filling in the numbers gives
vcyl - vcon = π(9²)(9) - (1/3)(9²)(9) . . . matches choice a
comment on notation
exponents rarely get copied properly from other applications to brainly, so some editing may be required. if you don't use the equation editor or special mathematical symbols, the plain-text form for an exponent is
(base)^(exponent) . . . the exponent is signified by a caret (^)
note that grouping symbols may be required. if the exponent has an arithmetic operation in it, then it needs parentheses:
√(x) = x^(1/2)
(x^a)(x^b) = x^(a+b)
the use of the word "over" to signify a fraction is unnecessary and ambiguous. the forward slash (/) is usually used for that purpose. as with the caret, any numerator or denominator consisting of more than a single number or letter needs parentheses: (1/a) + (1/b) = (a+b)/(ab). even if you know that the denominator is a single number, as in 1/3, it understanding to put the fraction in parentheses so the appropriate interpretation is clear. (see above for examples. many people write 1/x+1 when they mean 1/(x+1), so if you mean (1/x)+1, it is to write it that way--even though that is how it should be interpreted.)
Answer:
370 million
Step-by-step explanation:
In the 10 years from 2000 to 2010, the population was multiplied by the factor ...
100% + 9.6% = 109.6% = 1.096
In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:
2030 population = (308 million)·(1.096²) ≈ 370 million
Answer: c) B' = (6, -3)
<u>Step-by-step explanation:</u>
The simplest way is to rotate the graph.
Rotating the graph 1 time to the left (counterclockwise) = 90°
Rotating the graph 2 times to the left (counterclockwise) = 180°
Rotating the graph 3 times to the left (counterclockwise) = 270°
The longer way is to reflect over the x-axis and over the y-axis, which is the same as a rotation of 180°
Z = (x, y) → Z' = (-x, -y)
<em>the image below shows the graph rotated 2 times = 180°</em>

Answer:
x = 95
Step-by-step explanation:
Given that,
Jax scores on the last 5 tests are 78,92,86,94,95.
We need to find the score he need to have an average of 90.
The formula for average of few number is given by :
Average = sum of observations/total no of observation
Let he score x in test 6. So,
So, he must score 95 in the next test so that its average is 90.
