Solve the problem below.

(x - 5)² + 7y, if x = 144 and y = 16

Answer:

J

-66

Step-by-step explanation:

a1 = 2

n = 18

d = - 4

a18  =  a1 + (n - 1) * d

a18 = 2 + (18 - 1)*(-4)

a18 = 2 + 17*-4

a18 = 2 - 68

a18 = -66

Answer: 74feet

Step-by-step explanation:

In this case, to calculate the total length of the path, we have to find the perimeter of the shape which is a triangle.

It should be noted that the perimeter of a triangle is the addition of all of its sides. The sides given here are 20 feet, 36 feet, and 18 feet. Therefore, the total length will be:

= 20ft + 36ft + 18ft

= 74ft

The perimeter of a triangle is the sum of all sides of the triangle. Then the path length is 74 feet.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

Rowena and Arlene are going to make a triangular path in her garden.

The sides will be 20 feet, 36 feet, and 18 feet.

The length of the path is given by the perimeter of the triangle. Then we have

Length of path = 20 + 36 + 18

Length of path = 74 ft.

Answer:

[tex]12(x - 2) + 3x = \frac{1}{3} (x + 12) + 10x \\ 12x - 24 + 3x = \frac{x}{3} + \frac{12}{3} + 10x \\ 12x - 24 + 3x = \frac{x}{3} + 4 + 10x \\ 12x + 3x - \frac{x}{3} - 10x = 4 + 24 \\ 5x - \frac{x}{3} = 28 \\ \frac{15x - x}{3} = 28 \\ \frac{14x}{3} = 28 \\ 14x = 28 \times 3 \\ 14x = 84 \\ x = \frac{84}{14} \\ x = 6[/tex]

Answer:

13 degrees

Step-by-step explanation:

Triangles have to equal to 180 degrees

Answer:

[tex]180 = 154 + 13 + x[/tex]

Step-by-step explanation:

180= 154° + 13° + X

X = 180° - 154°- 13°

X = 13°

Answer:

y = [tex]\frac{4}{3}[/tex][tex]x[/tex] [tex]-7[/tex]

Step-by-step explanation:

Use the points (9, 5) and (6, 1) to identify the slope of the graph

[tex]m[/tex] = [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]

m = [tex]\frac{1-5}{6-9}[/tex]

m = [tex]\frac{-4}{-3}[/tex]

m = [tex]\frac{4}{3}[/tex]

The y-intercept is -7 because -7 touches y axis causing it to be the y-intercept

Answer:

t = 3.46 hours, or 3 hours 28 minutes

Step-by-step explanation:

78 dozen donuts in 2 hours immediately reduces to 39 dozen/hour.

Donuts produced as a function of time:   D(t), where t is the number of hours the macine runs.

Set D(t) = 135 dozen = (39 dozen/hr)t.

Solving this equation for t, we get:

t = 135/39 hours, or t = 3.46 hours, or 3 hours 28 minutes

The sum of three consecutive number is 63, hence the number is 20.

An equation is an expression that shows the relationship between two numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.

Let x represent the number. The sum of three consecutive number is 63, hence:

x + (x + 1) + (x + 2) = 63

x = 20

The sum of three consecutive number is 63, hence the number is 20.

Answer:

'y' would be 24

'x' would be 12[tex]\sqrt{3}[/tex]

Step-by-step explanation:

the ratio of sides in a 30-60-90 triangle is, respectively, 1 : [tex]\sqrt{3}[/tex] : 2

so the side across from the 60 degree angle is [tex]\sqrt{3}[/tex] times the side of the 30°

the side across from the 90 degree angle is double the side of the 30°

so in this problem 'y' would be 24 and 'x' would be 12[tex]\sqrt{3}[/tex]

Answer:

Step-by-step explanation:

take 30 degree as reference angle

using sin rule

sin 30=opposite/hypotenuse

Answer:

  a. 12

  b. 15

  c. (2, -2.5)

Step-by-step explanation:

a. The points lie on a horizontal line, so the distance between them is the difference of their x-coordinates: 4 -(-8) = 12 units.

__

b. The length BD is the diagonal of the rectangle. Its length is given by the distance formula as ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((-8 -4)^2 +(-7 -2)^2) = √((-12)^2 +(-9)^2) = √(144 +81) = √225

  d = 15

The distance between B and D is 15 units.

__

c. The midpoints of AC and BD are the same:

  (A +C)/2 = ((-8, 2) +(4, -7))/2 = (4, -5)/2 = (2, -2.5)

  (B +D)/2 = ((4, 2) +(-8, -7))/2 = (4, -5)/2 = (2, -2.5)

Point (2, -2.5) can be used to locate the lake.

Explanation:

The number of sophmores is 2+25+3 = 30.

Of these sophmores, 2 drive to school.

So the probability that a student drives to school, given that they are a sophmore, is 2/30, or approximately 0.07.

Answer:

D. y = –3x2

Step-by-step explanation:

Answer:

y = -3x^2

Step-by-step explanation:

A quadratic function has a leading coefficient which determines its width. When |a| < 1 the graph is wider. When |a| > 1 the graph is narrower. This means y = -3x^2 is the narrowest graph since 3 is the greatest.

Answer:

The area is about 25/2 inches^2

Step-by-step explanation:

You are given an isoceles triangle; the sides equal to each other are radiuses of the circle G.  They are both 5 inches in length.  

The angle between the two equal sides is equal to 88 degrees.

To find the height of the triangle, draw a line perpendicular to  GH and solve for the lengths of the sides.  

sin(88) = x/5

5sin88 is about 5 it is (4.99695)

Multiply the side length GH (5) and the solved height and divide by two;

The area is about 25/2 inches^2
