Match with the sum of the monomial and binomial

Margarita [4]

Answer:

The answer to your question is below

Step-by-step explanation:

Just cancel the parentheses and simplify

Result Addition

5xy² + 2x²y ⇒ (5xy² - x²y) + 3x²y = 5xy² + 2x²y

-3x²y - 2xy² ⇒ x²y + (-2xy² - 4x²y) = -3x²y - 2xy²

3x²y - 2xy² ⇒ 2x²y + (x²y - 2xy²) = 3x²y - 2xy²

5x²y + xy² ⇒ 4x²y + (x²y + xy²) = 5x²y + xy²

Frank Fitness found a correlation coefficient of -0.74 between hours of strenuous exercise each week and a standard measure of b

Evgen [1.6K]

Answer:

b. strong; negative

Step-by-step explanation:

When a correlation has a value greater than 0.74 or lesser than -0.70, it is classified as a strong correlation.

A negative value for a correlation means a negative (downhill) linear correlation.

Therefore, since the correlation coefficient found by Frank Fitness is -0.74, there is a strong and negative relationship between hours of strenuous exercise and body mass.

Find a single expression that represents the area of the outer ring of the circle if the area of the whole circle is represented

sp2606 [1]

Answer: The answer is $A_o=2\pi\sqrt{\dfrac{7}{22}(25x^2-12x-9)}.$

Step-by-step explanation: Given that the area of the whole circle is represented by the expression

$A_c=25x^2-12x-9.$

We are to find the area of the outer ring of the circle, i.e., to find the circumference of the circle.

Now, if 'r' represents the radius of the circle, then we have

$A_c=\pi r^2\\\\\Rightarrow \dfrac{22}{7}r^2=25x^2-12x-9\\\\ \Rightarrow r^2=\dfrac{7}{22}(25x^2-12x-9)\\\\\Rightarrow r=\sqrt{\dfrac{7}{22}(25x^2-12x-9)}.$

Thus, the area of the outer ring is

$A_o=2\pi r=2\pi\sqrt{\dfrac{7}{22}(25x^2-12x-9)}.$

norma cut a triangle out of construction paper for an art project. the area of the triangle os 84.5 square centimeters. select t

qwelly [4]

Answer:

h = 13

Step-by-step explanation:

Given the area of a triangle as 84.5 .

The correct value to complete the formula to calculate for the height h is 13 .

Area of a triangle = 1/2 b x h

b = base

h = height

Using the above formula

84.5 = 1/2 x 13 x h

84.5 = 13/2 x h

84.5 = 6.5 x h

84.5 = 6.5h

Divide both sides by 6.5 to get h

84.5/6.5 = 6.5h /6.5

13 = h

h = 13
