Answer:

Slop of the line M = -2

Step-by-step explanation:

Given coordinates;

(-1 , 1) , (3 , -7)

Find:

Slop of the line

Computation:

We know that;

x1 = -1

x2 = 3

y1 = 1

y2 = -7

Slop of the line M = Δy / Δx

Slop of the line M = (y2 - y1) / (x2 - x1)

Slop of the line M = (-7 - 1) / [3 - (-1)]

Slop of the line M = (-8) / [3 + 1]

Slop of the line M = (-8) / (4)

Slop of the line M = -2

Answer:

After 3 seconds

Step-by-step explanation:

Given

[tex]h(t) = -16t^2 + 96t[/tex]

Required

Seconds to attain maximum height

The maximum of a quadratic function [tex]y = ax^2 + bx + c[/tex] is calculated using:

[tex]x = -\frac{b}{2a}[/tex]

So, we have:

[tex]t = -\frac{b}{2a}[/tex]

Where:

[tex]a = -16[/tex] and [tex]b = 96[/tex]

So:

[tex]t = -\frac{96}{2 * -16}[/tex]

[tex]t = -\frac{96}{-32}[/tex]

Cancel out negatives

[tex]t = \frac{96}{32}[/tex]

[tex]t = 3[/tex]

Answer:

w = 12°

Step-by-step explanation:

Angle J = Angle H

Angle K = Angle I

So lets find the sum of the entirety of angles

360° = 2w + 34° + 2w + 34° + 4w + 74° + 4w + 74°

360° = 12w + 68° + 148°

360° = 12w + 216°

Subtract 216° from both sides

360° - 216° = 12w + 216° - 216°

144° = 12w

Divide both sides by 12

144°/12 = 12w/12

12 = w

w = 12°

Answer:

The surface area of the green prism is 2.5 times greater than the surface area of the blue prism

Answer:

Step-by-step explanation:

I'll focus on -10v^2=-810 and will aim to find the solution, v.  Dividing both sides by -10, we get v^2 = 81, so that v = ±9 (two roots).

The other equation, 7r^2 = -70, has no real solutions.

r^2 = -70 yields r = ±i√10 (two imaginary solutions)

Answer:

[tex]\$1583.33[/tex]

Step-by-step explanation:

Let [tex]d[/tex] be the amount of money you need to save each month to have the full $23,000.

We can write the following inequality:

[tex]4,000+12d\geq 23,000[/tex]

Solving for [tex]d[/tex]:

[tex]4,000+12d\geq 23,000,\\12d\geq 19,000\\d\geq \approx \boxed{\$1583.33}[/tex]

Step-by-step explanation:

Find the diagram attached

Using the similarity theorem of a triangle;

GH/FG = FG/EF

x/15 = 36/39

x/15 = 12/13

Cross multiply

13x = 12 * 15

13x = 180

x = 180/13

x = 13.85

Hence the value of x to the nearest hundredth is 13.85

Answer:

6.650, 6.68, 6.803, 6.82

Step-by-step explanation:

You just treat the decimals as you would whole numbers. Try imagineing them as whole numbers and its a lot easier like this. 6.82 and 6.68 as 682 and 668, you can clearly see 668 is lower than 682 so it comes first. Therefore, 6.68 is lower than 6.82 and comes first.

Jack is wrong because he used the distributive property wrong. On the top equation, you see 2(4k - 3). The 2 multiplies into the (), so basically you have

2 x 4k - 2 x 3

which gives you

8k - 6

Answer:

Taniyah

Step-by-step explanation:

Taniyah is correct because you need to:

diistribute : 8k - 6 - 6k = 14

combine like terms : 2k - 6 = 14

add 6 to both sides : 2k - 6 + 6 = 14 + 6

simplify : 2k = 20

divide both sides by the same factor : 2k/2 = 20/2

simplify : k = 10

Answer:

The slope is 1

Step-by-step explanation:

Slope = (y₂-y₁)/(x₂-x₁) = (2-3)/(4-5) = (-1)/(-1) = 1

Therefore, the slope of the line that passes through (5,3) and (4,2) is 1

Answer:

$1783.03

Step-by-step explanation:

Annually compounding interest formula:

PV(1+i)ⁿ

1500(1+.025)⁷

1500(1.025)⁷

1783.028631

which rounds to

1783.03

Answer:

$1783.03

Step-by-step explanation:

You use the formula for finding the interest rate.

So 1500(1+.025)^7

Which you put that in a calculator and it comes to out to 1783.0286. Then just round up.

Hope this helps

Answer:

Solution given:

The length of the garden[l] = 2434 feet.

breadth or width [b]=b

perimeter of his garden = 7012 feet.

2[l+b]=7012ft

2434+b=7012/2

b=3506-2434

b=1072

So the width of the garden is 1072ft.
