What is the standard form of the following equation?
y= 2(x - 1)^2 + 4

A) y = 2x2 + 4
B) y = 2x² - 4x + 8
C) y = 2x2 – 2x + 4
D) y= 2x2 - 4x + 6​

Answers

y = 2(x - 1)² + 4

y = 2(x² - 2x + 1) + 4

y = 2x² - 4x + 2 + 4

y = 2x² - 4x + 6

Select all values that would make the following inequality true: x ≥ -10

-10

-14

-2

0

Answers

Answer:  -10; -2; 0

Step-by-step explanation:

≥ means greater or equal than.

-10 is equal -10, true.

-14 is less than -10, so false.

-2 is greater than -10, true

0 is greater than -10, true

so the answer is -10, -2 and 0 can make this inequality true.

Use the Triangle Inequality Property to determine whether a triangle can be formed with the given side lengths. 4 m, 8 m, 9 m *

Answers

Answer:

Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.

The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:

a + b > c;   a + c > b;   b + c > a

Given a triangle with side length 4 m, 8 m, 9 m:

4m + 8m = 12m > 9m

4m + 9m = 13m > 8m

8m + 9m = 17m > 4m

Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.

if the simple interest on 2000 for 4 years is 4000 then what is the interest rate

Answers

Answer:

Principal = Rs 2000

Time = 4 years

Interest = Rs 400

Now, Interest= Principal×Rate×Time/100

400= 2000×R×4/100

R= 400×100/2000×4

If a coordinate was dilated from (-3, 2) to (-6, 4), what was the scale factor used?

Answers

Given:

A coordinate pair was dilated from (-3, 2) to (-6, 4).

To find:

The scale factor.

Solution:

We need to divide the coordinate of dilated point by the corresponding coordinate of original point to find the scale factor.

The value of scale factor is:

[tex]k=\dfrac{x\text{-coordinate of image}}{x\text{-coordinate of original point}}[/tex]

[tex]k=\dfrac{-6}{-3}[/tex]

[tex]k=2[/tex]

Therefore, the scale factor is 2.

A central angle 0, in a circle of radius 4 ft intercepts an arc length of 50 ft.
Calculate the radian measure of 0.

Answers

Given:

The central angle = [tex]\theta[/tex]

Radius of the circle = 4 ft

Intercepted arc length = 50ft

To find:

The value of [tex]\theta [/tex] in radian measure.

Solution:

The formula for arc length is

[tex]s=r\theta[/tex]

where, r is radius and [tex]\theta [/tex] is the central angle in radians.

Putting s=50 and r=4, we get

[tex]50=4\theta[/tex]

Divide both sides by 4.

[tex]\dfrac{50}{4}=\theta[/tex]

[tex]12.5=\theta[/tex]

Therefore, the value of [tex]\theta [/tex] is 12.5 radians.
