Slope intercept form is y=mx+b  because m=slope and b=y-intercept hence "slope intercept form"...

m=deltay/deltax=(0-5)/(-9--6)=-5/-3=5/3 so far we have now:

y=5x/3 +b, using any point, I'll use (-9,0) we can now solve for b or the y-intercept...

0=-9(5)/3 +b

0=-15+b, so b=15 and our line is:

y=5x/3 + 15 or more neatly

y=(5x+45)/3

A solid has a circular base of radius 3. If every plane cross section perpendicular to the x-axis is an equilateral triangle, th
almond37 [142]
Letter E is correct.
Area of equilateral trianlge= (1/2) tiime a^2 square root 3
Equation for the base is = x^2+y^2 =9

at x ,
y= square root (9-x^2)
Side of triangle a= 2y

d times Volume = (1/2)a^2 square root 3 dx

d times V= (square root 3) (9-x^2) dx

V= square root 3 INT (9-x^2) dx
-3V= 2square root INT (9-x^2) dx
0
V= 2 square root 3 ( 9x-x^3/3)

V=2 square root 3 ( 27-9)
V= 36 square root 3

The answer is E.

Question 5 (1 point)
Rus_ich [418]

Answer:

b = 11

Step-by-step explanation:

the standard form of a quadratic equation is ax² + bx + c = 0 ( a ≠ 0 )

given

x² + 28 = - 11x ( add 11x to both sides )

x² + 11x + 28 = 0 ← in standard form

with b = 11

The area of a rectangle is 42 square inches. the length is 7 inches.what is the perimeter of the rectangle?
andrew11 [14]

In order to find the perimeter, we need to have the length and the width. We are told that the area of the rectangle is 42. We will use that in the area formula, length times width, to solve for w. 42 = 7w so w = 6. The length is 7 and the width is 6. The perimeter formula for a rectangle is P = 2L + 2W. We have both the length and the width now, so we fill in accordingly. P = 2(7) + 2(6). And P=14+12. The perimeter then is 26 inches.

What is the actual length of the living space if the length of the scale drawing is 16.8 centimeters? Enter your answer in the b
algol13
<h2>Answer:</h2><h2></h2><h3>21m</h3><h2></h2><h2>Explanation:</h2><h2></h2>

The diagram and complete question is shown below. We know that the length (L) of the living scale in the drawing is:

L=16.8cm

We also know that the scale is:

Scale:2cm=2.5m

Then, by using proportion we have:

\frac{2.5m}{2cm}=\frac{x}{16.8cm} \\ \\ \\ Isolating \ x: \\ \\ x=\frac{2.5m}{2cm}(16.8cm) \\ \\ \boxed{x=21m}
