Answer:

y = (x-4)²

Step-by-step explanation:

vertex (h , k)

h = 4   .... axis of symmetry

k = (6 + -6) / 2 = 0  .... midpoint of focus and directrix

equation of parabola: y = (x-4)²       y = (x-h)² + k

Answer:

answer is A

sum of angles = 180

5x -20 + 3x +5 + 2x - 15 =180

10x = 180 + 30

10x=210

x=21

A=3×21+5

=68

Answer:

Step-by-step explanation:

1) the temperature rise, because 8.5 is C higher than 0 C

2) 8.5 - 0 = 8.5

So it rised by 8.5 degrees ( to know how many dgrees is is rised subtract the second number from the first number)

Answer:

x=34

Step-by-step explanation:

Again we are given an angle's ( x to be more specific )  opposite side length and the adjacent side length so we will use trig ratio tangent

Recall that tan = opposite over hypotenuse

[tex]tan(x)=\frac{29}{43}[/tex]

* multiply each side by the inverse of tan ( [tex](tan)^-^1[/tex] )

[tex]tan(x)*tan^-^1=x\\tan^-1*\frac{29}{43} =33.99645915\\x=33.99645915[/tex]

Finally we round to the nearest tenth of a degree and get that x = 34

Answer: 18/91 or ≈ 0.2

Step-by-step explanation:

Bag one: 4 red + 3 blue = 7 total

Bag two: 7 green + 6 yellow = 13 total

probability of picking blue from first bag: 3/7

probability of picking yellow from second bag: 6/13

3/7*6/13 = 18/91 or about 0.2 chance

Step-by-step explanation:

Answer:  Choice C

Point D is 8 units to the left of point G

=================================================

Explanation:

Refer to the diagram below. I've graphed both points on the same xy grid. We can draw a horizontal line through points D and G to form a number line of sorts. Count the number of spaces along this number line to go from G to D. You should count 8 spaces to the left.

Effectively, this is the same as drawing a number line and plotting -10 and -2 on this number line. We only worry about the x coordinates of the two points since the y coordinates are the same (both are y = -3). Note how -10 is eight units to the left of -2 on the number line.

Answer:

B. 1/2

Step-by-step explanation:

because 8y=4

solve for y which is,

8/8y = 4/8 ( devide by 8 to remove 8 from y to let y alone, so what you to on the right hand side you do on the left and vice versa, so devide 4/8 as well.)

y = 4/8

y = 1 /2 ( simplify )

Answer:

uhm 0 degrees

Step-by-step explanation:

The value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.

Simply put, inverse trigonometric operations are the opposites of the fundamental trigonometric parameters sine, cosine, secant, cosecant, tangent, and cotangent.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The inverse trigonometric expression is given below.

⇒ sin⁻¹(sin 17°)

We know that the value of sin⁻¹(sin θ) is θ.

Then the value of the inverse trigonometric expression will be

⇒ sin⁻¹(sin 17°)

⇒ 17°

Thus, the value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.

Step-by-step explanation:

Answer:

C.72

Step-by-step explanation:

angle XYZ is an inscribed angle and arc XZ is the arc it intercepts

If you didn't know the measure of an inscribed angle is equal to half the measure of its arc it intercepts or an intercepted arc equals twice the measure of its inscribed angle

Hence, angle XYZ * 2= arc XZ

If Angle XYZ = 36

then 36 * 2 = arc XZ

36 * 2 = 72

hence the answer is C

The measure of arc is 72 degree, the correct option is C.

An arc is formed by two radii and their intercepted part on the circumference.

According to the theorem of arc and subtended angles, the central angle subtended by the arc is double the angle subtended by it on the circumference.

The angle subtended by arc XZ on the circumference is 36 degree.

The angle subtended by the arc at the center is = 2 * 36 = 72 degree.

The arc subtended by the arc at the center of the circle is the measure of the arc.

Answer:

Area of background without flower bed = 575 feet²

Step-by-step explanation:

Given:

Length of rectangle ground = 35 feet

Width of rectangle ground = 20 feet

Height of triangle bed = 10 feet

Base of triangle bed = 25 feet

Find:

Area of background without flower bed

Computation;

Area of background without flower bed = Area of rectangle - Area of triangle

Area of background without flower bed = [l x b] - (1/2)(b)(h)

Area of background without flower bed = [35 x 20] - (1/2)(25)(10)

Area of background without flower bed = 700 - 125

Area of background without flower bed = 575 feet²

Answer:

125 for the backyard with the flower bed, and the backyard that does not include the flower bed is 575 square feet :)

Answer:

Step-by-step explanation:

1.  Find the circumference of the cylinder:  C = 2πr

2.  Multiply this result by the height of the cylinder:  A = 2πr·h

3.  To this result add the surface areas (there are two) of the ends of the cylinder:  2πrh + 2πr²

This is the correct general formula for the surface area of a cylinder of  radius r and height h.  If you want specific numbers, please share the values of r and h.

Answer:

[tex]W=15ft[/tex]

[tex]L=20ft[/tex]

Step-by-step explanation:

From the question we are told that:

Length of Bed [tex]L=5+W[/tex]

Width of sidewalk [tex]W_s=3ft[/tex]

Area of the bed and sidewalk [tex]A_t= 546ft^2[/tex]

Generally the equation for Area of the bed and sidewalk[tex]A_t[/tex] is mathematically given by

 [tex]Area=L*B[/tex]

 [tex]A_t=((3+3)+L)*((3+3)+W)[/tex]

Therefore

 [tex]546=((3+3)+(5+W))*((3+3)+W)[/tex]

 [tex]0=((6+(5+W))*((6)+W)-546[/tex]

 [tex](11+W)*(6+W)-546=0[/tex]

 [tex]W^2+17B-480=0[/tex]

Solving the Quadratic Equation

 [tex]W=15ft[/tex] (Using only positive root)

Generally the Length L is mathematically given by

 [tex]L=5+15[/tex]

 [tex]L=20ft[/tex]
