Answer:
The answer to your question is: 35 yd²
Step-by-step explanation:
To solve this problem, just find the data, the formula, substitute the values in the formula and find the result.
Data
Square yards = ?
Length = 21 ft
Width = 15 ft
Formula
Area of a rectangle = length x width
Substitution
Area of a rectangle = 21 ft x 15 ft
Area of a rectangle = 315 ft²
Area of a rectangle = square yards of carpet
Finally, convert ft² to yd²
315 ft² = 35 yd²
Result
Square yards of carpet = 35 yt²
Answer: 0.015625
Step-by-step explanation:
i noticed the pattern. it is getting divided by 2 each time. so, i just divided each new number by 2 and got 0.015625.
Answer: 6
Step-by-step explanation: 8 times 3/4 equals to 6.
<span>the product of a number and the same number less 3
x(x – 3)</span>
The words "the product of" tell us we're going to multiply a number times the number less 3. In this case, we'll use parentheses to represent the multiplication. The words "less 3" tell us to subtract three from the unknown number.
a number divided by the same number less five
The words "divided by" tell us we're going to divide a number by the difference of the number and 5. In this case, we'll use a fraction to represent the division. The words "less 5" tell us we need a minus sign because we're going to subtract five.

Answer:
The rate of change of blood pressure at the 50-pound weight level is 0.26
The rate of change of blood pressure at the 80-pound weight level is 0.16
Step-by-step explanation:
We have, P(x) = 12.9(9 + ln x)
We need to compute the rate of change of blood pressure P(x) so, we will differentiate the function P(x) with respect to x.
P(x) = 12.9(9 + ln x)
P(x) = 116.1 + 12.9ln x
Differentiating with repect to x:
= 0 + 12.9 (
)
= 12.9 ()
The differential of ln x is and the differential of constant terms is 0.
The rate of change of blood pressure at the 50-pound weight level can be calculate by substituting 50 in place of x, so
= 12.9 ()
= 12.9 * (1/50)
= 0.258
= 0.26
Similarly, The rate of change of blood pressure at the 80-pound weight level can be calculate by substituting 80 in place of x, so
= 12.9 ()
= 12.9 * (1/80)
= 0.16125
= 0.16
