Answer

D. `(y+4) = (5)/(3)(x+ 1)`

Step by step explanation

The given points are (-1, -4) and (2, 1)

Slope = (y2 - y1)/(x2 - x1)

= (1 - (-4)) / (2 - (-1))

= (1 + 4) / (2 +1)

m = 5/3

When two points are given, the equation of the line is

(y - y1) = m (x - x1)

y -(-4) = 5/3 (x - (-1))

y + 4 = 5/3 (x + 1)

The answer is (y+4) = (5)/(3)(x+ 1)

Thank you.

Lateral Area:

We have four congruent triangles with base b = 16cm and height h = 12cm.

The formula of an area of a traingle:

$A_\triangle=\dfrac{bh}{2}$

Substitute:

$A_\triangle=\dfrac{(16)(12)}{2}=(8)(12)=96\ cm^2$

$L.A.=4A_\triangle=4(96)=384\ cm^2$

Surface Area:

$S.A.=B+L.A.$

In the base we have the square with side s = 16cm. The formula of an area of a square:

$A_\square=s^2$

Substitute:

$B=16^2=256\ cm^2$

$S.A.=256\ cm^2+384\ cm^2=640\ cm^2$

Write the equation of the line in fully simplified slope-intercept form.

iren2701 [21]

Y=Mx+b

Rise / run between any two points = slope (m)
Where the line crosses the y axis is (yint) (b)

Slope is -1/2
Yint = -8

So the equation is y=(-1/2)x - 8

Answer:

This is an geometric sequence with a common ratio <em>r</em> of 1/2

Step-by-step explanation:

When you find out <em>r</em>, you realize the ratio between the numbers to be dividing by 2, or 1/2. Since it is <em>r</em> and not common difference <em>d</em>, it is an geometric sequence.

Olenka [21]

Answer:

x = 67/4

Step-by-step explanation:

Let x = smaller number and y = bigger number

Then x +y = 64 and y = 3x-3

Plugging y into x+y = 64

x + 3x -3 = 64

4x = 67

x = 67/4

Hope it helps.

What is the surface area, in square inches, of a sphere with a diameter of 8 in.? and round to the nearest whole number. Enter o

grin007 [14]

Answer:

SA = 201 in^2

Step-by-step explanation:

The formula for surface area of a sphere is

SA = 4pi r^2

We know that the diameter is 8

To find the radius we cut the diameter in half.

r = d/2

r = 8/2 =4

Substitute in what we know.

SA = 4 *pi *4^2

= 4*pi*16

= 64*pi

Letting pi = 3.14

= 200.96 in^2

We want to round to the nearest whole number

SA = 201 in^2
