Answer:
5sqrt3
Step-by-step explanation:
Using the pythagorean theorem, we have a^2+4^2=9^2
a^2 + 16 = 81
a^2 = 75.
a = sqrt75.
75 = 25*3. 25 is a perfect square, so sqrt75 = 5sqrt3
So the right answer is B 942 ft^2
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
5.2v - (30 ÷ 6) + 12
<u>9) We need to determine which part of the expression represents a quotient?</u>
We know that when we divide one rational expression by another, the result would be termed as 'quotient'.
Here, it is clear that:
(30 ÷ 6) represents the expression part for a quotient.
When we divide 30 by 6, we get the result 5 which would be the quotient of the expression 30 ÷ 6.
10. Which part of the expression represents a product of two factors?
We know that when a multiply two number, we get the product. The multiplying numbers are the factors of the product.
For example, 4 × 9 = 36 therefore, 4 and 9 are the factors of 36.
In our case, 5.2v represents a product of two factors 5.2 and v. In other words, 5.2 and v are the factors of the product of 5.2v.
The percentage of published studies that supported the tested hypothesis has changed from 70 to 85% over the past 25 years.
Hypothesis testing:
A hypothesis testing means investigates a proposed mathematical model to determine whether there is sufficient evidence from a sample of data to reject the defined null hypothesis.
Given,
The percentage of published studies that supported the tested hypothesis has changed from _____ to _____ over the past 25 years.
Here we need to find the change in the percentage for the past 25 years.
Based on the details, the percentage of published studies that supported the tested hypothesis has changed from 70 to 85% over the past 25 years.

Answer:
The equation of the line is y = 2x - 2
Step-by-step explanation:
In order to find this, we first need to find the slope. For that we use slope intercept form.
m(slope) = (y2 - y1)/(x2 - x1)
m = (6 - 4)/(4 -3)
m = 2/1
m =2
Now that we have this, we can use the slope and either point in slope-intercept form to get the equation.
y - y1 = m(x - x1)
y - 4 = 2(x - 3)
y - 4 = 2x - 6
y = 2x - 2
