Answer:

y= -1/2x-5

Step-by-step explanation:

The reciprocal of 2 is -1/2, and the y-intercept given is -5. Given those, the equation is y= -1/2x - 5

The equation of a line perpendicular to y=2x-5y=2x−5 that passes through the point (2, -5) = 2y = -x -8

The equation of line is an algebraic form of representing the set of points.

Given that a line is perpendicular to line, y = 2x -5 and passes through (2,-5)

Equation of a line = y = mx + c, where m is the slope

y = 2x - 5, slope of this line is 2

Slope of two perpendicular lines are negative reciprocal of each other.

Therefore, slope of other line is -1/2

Equation will be y = -1/2 x + c

This above line passes through (2,-5)

-5 = -1/2*2 + c

c = -4

Hence, the equation of a line perpendicular to y=2x-5y=2x−5 that passes through the point (2, -5).

y = -x/2 -4

2y = -x -8

Answer:

Approximately 6.3405 feet

Step-by-step explanation:

Our trigonometric ratio will be tangent in this case, since we are working with the opposite and adjacent sides.

Our equation that we set up will end up being [tex]tan\theta=o/a[/tex]

[tex]tan(26)=x/13[/tex]

Answer:

Find Radius using distance formula.

[tex]radius = \sqrt{(8 -- 7)^2 +(7--1)^2} \\[/tex]

            =[tex]\sqrt{15^2 + 8^2} = \sqrt{225 + 64 } =\sqrt{289} = 17 units[/tex]

Since the point (-15, y) lies on the circle. The distance between (-7, -1) and

(-15, y ) will be 17 units.

So again using distance formula we will find y.

[tex]radius = \sqrt{(-7 --15)^2 + (-1-y)^2} \\\\17 = \sqrt{8^2 + (y+1)^2}\\\\squaring \ both \ sides \\\\289 = 64 + (y+1)^2\\\\289-64=(y+1)^2\\\\225 = (y+1)^2\\\\taking \ squaring \ root\\\\15 = y+1\\\\y=14[/tex]

Answer:

The area would be multipled by 8

Step-by-step explanation:

Say you have a rectangle with the length of 5 and the width of 3, the area would be 15. Double the length, 10, and quadruple the width, 12. The area would be 120. 15 × 8 = 120.

Answer:

y = -1/2 x - 1

Step-by-step explanation:

The expression in point-slope form is expressed as;

y-y0 = m(x-x0)

(x0,y0) = (6, -4)

slope m = -1/2

Substitute into the formula

y-(-4) = -1/2(x-6)

y+4 = -1/2(x-6)

2(y+4) = -(x-6)

2y+8 = -x+6

2y = -x+6-8

2y = -x-2

y = -1/2 x -2/2

y = -1/2 x - 1

Hence the answer in slope-intercept form is y = -1/2 x - 1

Answer:

Step-by-step explanation:

Vertex form of the equation of a quadratic function with vertex (h,k):

f(x) = a(x - h)² + k

To find a we need to put the point and the vertex into this equation:

3 = a(-6 + 2)² - 13

10 = a(-4)²

16a = 10

a = ⁵/₈

Therefore, vertex form of the quadratic function:

f(x) = ⁵/₈(x+2)² - 13

Step-by-step explanation:

the formula for finding volume is

length x width x height

so 12 x 15 x 6 which is 1080.

Answer:It could be 10, 2, 3

Step-by-step explanation:

basically as long as the lengthxwidthxheight=60, then it should be fine

Answer:

Their are multiple ways you could do this but you can use 10 as the length, 3 as the width, and 2 as the height

Step-by-step explanation:

The formula for the volume of a rectangular prism is v=l*w*h  so plugging in our values would give us 10*3*2 which is equal to 60.

*see attachment for the figure

Answer:

x = 17 cm

Step-by-step explanation:

Total surface area of triangular prism = bh + L(s1 + s2 + s3)

Where,

Total surface area = 456 cm²

b = 8 cm

h = 6 cm

s1 = √(8² + 6²) = 10 cm (pythagorean theorem)

s2 = 8 cm

s3 = 6 cm

L = x

Plug in the values

465 = 8*6 + x(10 + 8 + 6)

465 = 48 + x(24)

465 - 48 = 24x

417 = 24x

417/24 = x

17.375 = x

x = 17 cm (approximated)

Answer:

The Volume of a Sphere is equal to 2 times the volume of a cone.

Step-by-step explanation:

The volume of a sphere: 4/3 π r^3

The volume of a cone: 1/3 π r^2 h  

r is the radius

h is the height

In this case, the height can be replaced by the 2r or the diameter, since it would correspond exactly to the height of the sphere of radius r.

So then,

sphere       and    cone

4/3 π r^3             1/3 π r^2 h  

                           1/3 π r^2 * 2r

                           2/3 π r^3    

Ratio sphere : cone

4/3: 2/3

2:1

Therefore the volume of the sphere is twice that of the cone or equal to twice the volume of the cone

Answer:

Let's find the area of 1 triangle (this may not be the formula but I'm doing it in a more easier way).

20(base) x 10.5(height) = 210

210 divided by 2 ( x 1/2) = 105

Since there are 4 sides we must multiply the area of 1 triangle four times! Since there are 4 sides of triangles.

105 x 4 = 420

Oh and I almost forgot! We need to find the area of the square below!

20 x 20 = 400!

Now we add both areas of all the triangles and the area of the bottom square:

420 + 400 = 820 in2 is your answer. (we use the unit 2 since we are finding areas and adding them up)
