What is the scale factor of point A (original point) to point B (new point) with P as the center of dilation.

Answer:

To find the slope of a line, simply use the slope formula [(y2-y2)/(x2-x1)].

To find the y-intercept, simply plug in point values to solve for b.

The line that passes through the two points (1, 5/2) and (-1/2,-1/4) is y=1.8x+0.7.

The given coordinate points are (1, 5/2) and (-1/2,-1/4).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

Substitute (x1, y1)=(1, 5/2)=(1, 2.5) and (x2, y2)=(-1/2, -1/4)=(-0.5, -0.25) in slope formula, we get

Slope =(-0.25-2.5)/(-0.5-1)

= -2.75/(-1.5)

= 1.8

Put m=1.8 and (x, y)=(1, 2.5) in y=mx+c, we get

2.5=1.8×1+c

c=0.7

So, equation is y=1.8x+0.7

Hence, the line that passes through the two points (1, 5/2) and (-1/2,-1/4) is y=1.8x+0.7.

Answer:

30 - 6{sqrt15}

Step-by-step explanation:

Answer:

k = 4

Step-by-step explanation:

if f(x) is divided by (x - h) then f(h) is the remainder

f(x) = 2x³ - 3x² + kx - 1

divided by (x - 1) , so h = 1 , then

2(1)³ - 3(1)² + k(1) - 1 = 2

2 - 3 + k - 1 = 2

- 2 + k = 2 ( add 2 to both sides )

k = 4

Answer:

77777

Step-by-step explanation:

In this case, the vertex is the lowest point of the V shaped curve.

The goal is to get the stuff inside the absolute value (the 2x-5) to be as small as possible, so we can get to the lowest point. In terms of absolute value, we want the 2x-5 to be equal to 0

This allows us to set up the equation below and solve for x.

2x-5 = 0

2x = 5

x = 5/2

x = (4+1)/2

x = 4/2 + 1/2

x = 2 + 1/2

x = 2 & 1/2

Answer:

Smaller number-47.5

Larger number-52.5

Step-by-step explanation:

We will make the smaller number x. If the smaller number is x, then the larger number will be equal to x+5. We also know that when we add the two numbers, we get 100. We can make the equation

x+x+5=100

100-5=95

2x=95

95/2=47.5

x=47.5

The smaller number equals 47.5 and the larger number is 47.5+5 which equals 52.5

area of triangle = ½ × base × height

so,

height = 5cm

base = 4cm

now,

→ 1/2 × 4 × 5

→ 2 × 5 = 10 cm²

therefore, area of the ∆AED is 10cm².

area of rectangle = l × b

length = 8cm

breadth/width = 5cm

now,

area of BCDE

→ 8 × 5 = 40 cm²

now,

area of,

→ ABCD = BCDE - ∆AED

→ ABCD = 40 - 10 = 30

therefore, required area of ABCD is 30cm².

hope this answer helps you dear...take care and may u have a great day ahead!

Answer:

∵ ABC is an isosceles  triangle

∵ m∠b = m∠c

∴ m∠b and m∠c = 180 - m∠a/2

= 180 - 50/2

= 130 /2

= 65°

∵ ∠c and ∠AMI are corresponding angles

∵ m∠AMl = m∠c = 65°  (1)

From (1)

∵ ∠AMC is striaght angle

∴ m∠IMC = 180 - m∠AMI

m∠IMC = 180 - 65

m∠IMC = 115°

Answer = 115°

Determine the domain and range of the given function:

y = –x4 + 4

This is just a garden-variety polynomial. There are no denominators (so no division-by-zero problems) and no radicals (so no square-root-of-a-negative problems). There are no problems with a polynomial. There are no values that I can't plug in for x. When I have a polynomial, the answer for the domain is always:

the domain is "all x".

The range will vary from polynomial to polynomial, and they probably won't even ask, but when they do, I look at the picture:

graph

The graph goes only as high as y = 4, but it will go as low as I like. Then:

The range is "all y ≤ 4".

[tex]\frac{1}{9}[/tex]

Step-by-step explanation:

Note the bar above 1 means 1 is repeating , that is

0.111..

We require 2 equations with the repeating digit placed after the decimal point

let x = 0.111.... (1) Multiply both sides by 10

10x = 1.111... (2)

Subtract (1) from (2) thus eliminating the repeating digit

9x = 1 ( divide both sides by 9 )

Answer: 38 meters per second

Step-by-step explanation:

Rachel's speed is 38 m/s.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

D = -38t + 220

So, t = 1

D = -38t + 220

D = -38(1) + 220

D = -38+ 200

D = 182 m

So, v = [tex](D_0 - D_1)[/tex] / t

v = ( 220- 182) /1

v = 38 m/s

Hence, Rachel's speed is 38 m/s.

If y = xy + x² + 1, then when x=-1,

dy/dx = -1/2

The rate of change of a function with respect to a variable are called Derivatives.

Given that, y = xy + x² + 1

Put x = -1 we get,

y = -1y + (-1)² + 1

y = -y + 1 + 1

y = 1

Now Differentiating the given equation w.r.t x

dy/dx = xdy/dx + y + 2x

dy/dx - xdy/dx = y + 2x

dy/dx (1 - x) = y + 2x

dy/dx = (y + 2x)/(1 - x)

Put x = -1 and y = 1 we get

dy/dx = (1 + 2(-1))/(1 - (-1))

dy/dx = -1/2

Hence, y = xy + x² + 1, then when x=-1,

dy/dx = -1/2

Answer:

y = 9/2x + 5

Step-by-step explanation:

ok first find the slope with equation (x2 - x1 over y2 - y1)

14 - 5 = 9/

2 - 0 2

so 9/2 is your slope so now pick one of the points (let's do 0, 5) and plug that into the slope intercept form (y = mx+b)

5 = 9/2(0)+b

9/2 • 0 = 0 so b = 5

so the answer is y = 9/2x + 5. hope this helps!
