Answer:

-0.0936538462

Step-by-step explanation:

Start by solving the right side of the equation

1 - 2.87 = -1.87

now we have:

3 + 5.2c = -1.87

subtract 3 from both sides to get:

5.2c = -4.87

divide both sides by 5.2 to get:

-0.0936538462

hope that's what you're looking for! :)

Answer:

Step-by-step explanation:

Given the height of the object as it drops from the observation deck expressed as;

h= -16t^2+152

To determine the the time it will take the object to be 8 feet above the valley floor, we will substitute h = 8 into the equation and calculate t as shown;

8 = -16t^2+152

subtract 8 from both sides

8-8 = -16t^2+152-8

0 =  -16t^2+144

0-144 =  -16t^2

-144 = -16t^2

16t^2 = 144

Divide both sides by 16;

16t^2/16 = 144/16

t^2 = 9

t = √9

t = 3seconds

Hence it will take 3 seconds for the object to be 8 feet above the valley floor

Answer:

Step-by-step explanation:

From the figure attached,

Coordinates of the vertices of the given rectangle ABCD,

A(3, 6), B(12, 6), C(12, 1) and D(3, 1)

Rule for the reflection of a point across x-axis,

(x, y) → (x, -y)

After reflection of the given rectangle across x-axis image points will be,

A(3, 6) → A'(3, -6)

B(12, 6) → B'(12, -6)

C(12, 1) → C'(12, -1)

D(3, 1) → D'(3, -1)

Now we can plot these points on the graph to get the image of rectangle ABCD.

Busy Village is how many times the population of Boring Town?

Answer: 7.1 meters

Step-by-step explanation:

Given that :

Height of platform from which Doug dived = 5 meters above water

Doug's position after diving = 2.1 meters below water surface

How far does Doug's dive take him?

Distance above water surface to water surface = 5m

Final position to water surface = 2.1 meters

Hence, total distance covered after dive ;

5 meters + 2.1 meters = 7.1 meters

Complete Question:

You plant an 8-inch spruce tree that grows 4 inches per year and a 14-inch hemlock tree that grows 6 inches per year.

The initial heights are shown.

Write a system of linear equations that represents this situation.

Answer:

[tex]s(x) = 8 + 4x[/tex]

[tex]h(x) = 14 + 6x[/tex]

Step-by-step explanation:

Given

Spruce Tree (s):

[tex]Initial\ Height = 8[/tex]

[tex]Growth = 4[/tex] (yearly)

Hemlock Tree (h):

[tex]Initial\ Height = 14[/tex]

[tex]Growth = 6[/tex] (yearly)

Required

Represent as system of linear equations

Let the number of years be x.

In both cases, the equation can be formed using:

[tex]Equation = Initial\ Height + Growth * x[/tex]

For Spruce Tree (s):

[tex]s(x) = 8 + 4 * x[/tex]

[tex]s(x) = 8 + 4x[/tex]

For Hemlock Tree (h):

[tex]h(x) = 14 + 6 * x[/tex]

[tex]h(x) = 14 + 6x[/tex]

Hence, the equations are [tex]s(x) = 8 + 4x[/tex] and [tex]h(x) = 14 + 6x[/tex]

Answer:

point-slope form:  [tex]y-3=-\frac{1}{3}(x - 3)[/tex]

slope-intercept form: [tex]y=-\frac{1}{3}x+4[/tex]

Step-by-step explanation:

point-slope form is: y - y1 = m(x - x1)

slope-intercept form is: y = mx + b

The formula used to find the slope(m): [tex]\frac{y2-y1}{x2-x1}[/tex]

(x1, y1) = (3, 3)

(x2, y2) = (-6, 6)

The first thing we need to do to write the equations is to find the slope. We can do this by inputting the given points into the slope formula:

[tex]\frac{6-3}{-6-3}[/tex]

Simplify:

6 - 3 = 3

-6 - 3 = -9

[tex]\frac{3}{-9} =-\frac{1}{3}[/tex]

The slope is [tex]-\frac{1}{3}[/tex]. We can now write the equation in point-slope form:

[tex]y-3=-\frac{1}{3}(x - 3)[/tex]

To write the equation in slope-intercept form, we need to find the value of b. To find its value, input the value of the slope and one point into the equation for slope-intercept form:

y = mx + b

3 = [tex]-\frac{1}{3}[/tex](3) + b

Now you can solve for b:

3 = [tex]-\frac{1}{3}[/tex](3) + b

3 = -1 + b

4 = b

Now that we know the value of b, we can write the equation in slope-intercept form:

[tex]y=-\frac{1}{3}x+4[/tex]

I hope this helps. :)

Equation in point-slope form of the line that passes through the given points (-6,6) and (3,3) is y=-1/3x+4.

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

The given two points are (-6,6) and (3,3)

x1=-6, y1=6, y1=3 and y2=3

m=y2-y1/x2-xq

m=3-6/3-(-6)

m=-3/9

m=-1/3

Hence slope of line is m=-1/3

To write the equation in slope-intercept form, we need to find the value of b. To find its value, input the value of the slope and one point into the equation for slope-intercept form:

y = mx + b

3=-1/3(3)+b

4=b

Now that we know the value of b, we can write the equation in slope-intercept form:

y=-1/3x+4

Hence equation in point-slope form of the line that passes through the given points (-6,6) and (3,3) is y=-1/3x+4.

Answer:

Step-by-step explanation:

24% out of 190 = 45.6

Answer:

5 1/8 - 2 5/6

Step-by-step explanation:

Answer: 2  7 /24

Answer:

2 7/24

Step-by-step explanation:

let’s go ahead and make these fractions have the same denominator.

1/8 and 5/6

what multiple do they share?

8 * 3 = 24

6 * 4 = 24

we will change their denominators to 24.

Now to change the numerator you have to multiply it by what you multiplied the denominator by:

1/8 * 3/3 = 3/24

5/6 * 4/4 = 20/24

now we will add the whole numbers to the fraction:

5/1 * 24/24 = 120/24

2/1 * 24/24 = 48/24

now add these to the correct fraction:

120/24 + 3/24 = 123/24

48/24 + 20/24 = 68/24

Now subtract!

123/24 -68/24 = 55/24

Simplify:

55/24 = 2 7/24

Step-by-step explanation:

The marked price of an article is 25% above the SP and the CP is 20% below the selling price. What is the rate of discount and the profit percentage?

Let C, M & S denote cost-price, marked-price & sell-price respectively of the article.

Hence from above data we get following relations,

M = (1 + 25/100)*S = 1.25*S ….. (1a)

C = (1 - 20/100)*S = 0.80*S ….. (1b)

From (1a) we get,

S = (100/125)*M = (4/5)*M

or S = (1 - 1/5)*M = (1 - 20/100)*M ….. (2a)

From (1b) we get,

S = (100/80)*C = (5/4)*M

or S = (1 + 1/4)*C = (1 + 25/100)*C ….. (2b)

Therefore

It is evident from (2a) that

the discount percentage = 20% [Ans]

It is evident from (2b) that

the profit percentage = 25% [Ans]
