In March, Delphine's house had 40% more snowfall than in February. Delphine's house had f centimeters of snowfall in February.
slamgirl [31]

Answer: Options 'C' and 'E' are correct.

Step-by-step explanation:

Since we have given that

Quantity of snowfall in February at Delphine's house be f centimeters

Quantity of snowfall in March at Delphine's house be 40% more than in February.

According to question,

40\%\ of\ f=0.4f\\\\Therefore,\\\\f+0.4f=1.4f

So, Options 'C' and 'E' are correct.

i.e. C) 1.4f

E) \frac{4}{10}f+f

A circle has the equation x2+ y2 = 9. What is the length of the radius?
Zarrin [17]

Answer:

The center is (0,0) and the radius is 3

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2+(y-k)^2 = r^2

Where (h,k) is the center and r is the radius

(x-0)^2+(y-0)^2 = 3^2

The center is (0,0) and the radius is 3

Find an equation of the line described below. Write the equation in slope-intercept form (solved for y), when possible.
SCORPION-xisa [38]

The equation of the line in slope-intercept form would be y = m(x - 1/5) - 8.

<h3>What is slope intercept form a straight line?</h3>

The slope-intercept form of a straight line is used to get the equation of a line. We need to know the slope of the line and the intercept where the line crosses the y-axis in order to use the slope-intercept formula.

One of the most popular ways to represent a line's equation is in the slope-intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope-intercept formula can be used to determine the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfills.

Since the slope is undefined in the given question, let us consider it as m.

Therefore, slope=m

Given points are 1/5 and -8, so x₁ = 1/5 and y₁ = -8

We know the formula is, y - y₁ = slope × (x - x₁)

Putting the values of x₁, y₁ and slope in the given formula we get,

y -(-8) = m × (x-1/5)

y = m(x-1/5) - 8

Hence, we get the required equation.
