Answer: Parallelogram Opposite Sides Converse

Step-by-step explanation:

There are 2 pairs of opposite congruent sides.

The probability that the result is green - tail is 1/6.

Spinner has three colors that are  red, green and yellow and coin has two sides that are  head or tail.

Divide the number of events by the number of possible outcomes

The sample space is,[tex]{(red - head; red - tail; green - head; green - tail; yellow - head; yellow - tail)}[/tex]In total there are 6 ways to combine different colors with coin sides.

Therefore ,the probability that the result is green - tail is 1/6.

Answer:

1/6

Step-by-step explanation:

The percentage of the total finance charge will the service charge is 15.65%. Then the correct option is D.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Sam is paying off his eight-year, $15,360 loan in semiannual installments.

The loan has an interest rate of 9.58%, compounded semiannually, and a service charge of $1,294.64. Once the loan has been fully paid off.

A = $15360

r = 0.0958/2 = 0.0479

n = 8 × 2 = 16

The periodic payment is given as

[tex]\rm A = P (\dfrac{1-(1+r)^{-n}}{r})[/tex]

Where P is Periodic payment

r = rate per period

n = number of period

Then we have

[tex]\rm 15360 = P(\dfrac{1-(1+0.0479)^{-16}}{0.0479})\\\\\\ P = 1396.16[/tex]

Then Sam will pay a total of 1396.16 × 16 = $22,338.56

Interest charge = 22338.56 – 15360 = $6978.56

Total finance charge = 6978.56 + 1294.64 = $8273.20

Then the percentage of the total finance charge will the service charge will be

[tex]\rm Percentage = \dfrac{1294.64}{8273.20}*100\\\\Percentage = 15.65 \%[/tex]

Answer:

51.63 m²

Step-by-step explanation:

[tex]\textsf{Area of a semicircle} =\dfrac12\pi r^2[/tex]

Given:

[tex]\implies \textsf{area}=\dfrac12 \times 3.14 \times 3^2=14.13[/tex]

[tex]\textsf{Area of a triangle} =\dfrac12 \times \textsf{base} \times \textsf{height}[/tex]

Given:

[tex]\implies \textsf{area}=\dfrac12 \times 3 \times 5=7.5[/tex]

[tex]\textsf{Area of a rectangle} =\textsf{width} \times \textsf{length}[/tex]

Given:

[tex]\implies \textsf{area}=5 \times 6=30[/tex]

Total area = area of semicircle + area of triangle + area of rectangle

                 = 14.13 + 7.5 + 30

                  = 51.63 m²

Solution:

Step-1: Find the area of the triangle.

[tex]\text{Area of triangle} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]

[tex]\text{Area of triangle} = \dfrac{1}{2} \times 3 \times 5[/tex]

[tex]\text{Area of triangle} = 3 \times 2.5[/tex]

[tex]\text{Area of triangle} = 7.5 \ \text{m}^{2}[/tex]

Step-2: Find the area of the rectangle.

[tex]\text{Area of rectangle} = \text{LB}[/tex]

[tex]\text{Area of rectangle} = (6)(5)[/tex]

[tex]\text{Area of rectangle} = 30 \ \text{m}^{2}[/tex]

Step-3: Find the radius of the semi-circle.

[tex]\text{Diameter = 2(Radius)}[/tex]

[tex]6 \ \text{m = 2(Radius)}[/tex]

[tex]\dfrac{6}{2} \ \text{m} = \dfrac{2\text{(Radius)}}{2}[/tex]

[tex]3 \ \text{m} = \text{Radius}[/tex]

Step-4: Find the area of the semi-circle.

[tex]\text{Area of semi-circle} = \dfrac{\pi r^{2} }{2}[/tex]

[tex]\text{Area of semi-circle} = \dfrac{(3.14)( 3^{2} )}{2}[/tex]

[tex]\text{Area of semi-circle} = \dfrac{(3.14)(9 )}{2}[/tex]

[tex]\text{Area of semi-circle} = (3.14)(4.5 )[/tex]

[tex]\text{Area of semi-circle} = 14.13 \ \text{m}^{2}[/tex]

Step-5: Find the area of the figure.

[tex]\text{Area of figure = Area of triangle + Area of rectangle + Area of semicircle}[/tex]

[tex]\text{Area of figure = 7.5 + 30 + 14.13}[/tex]

Answer:

m = 5

Step-by-step explanation:

[tex] \frac{10}{m - 5} = \frac{8}{m - 5} \\ \\ 10(m - 5) = 8(m - 5) \\ \\ 10m - 50 = 8m - 40 \\ \\ 10m - 8m = 50 - 40 \\ \\ 2m = 10 \\ \\ m = \frac{10}{2} \\ \\ m = 5[/tex]

Answer:

m = 5

Step-by-step explanation:

Cross product to get: 10(m-5) = 8(m-5)

Solve for m:

10m-50 = 8m-40

10m - 8m = -40 + 50

2m = 10

m = 10/2

m = 5

Answer:

Multiply vector c by the scalar -1/2.

Step-by-step explanation:

Look at vector c.

It has an x component of 4 and a y component of 4.

You can write vector c as a sum of its components using unit vectors in the x direction (i) and in the y direction (j).

c = 4i + 4j

Now look at vector d, and write it also as a sum of its x and y components.

d = -2i - 2j

Now ask yourself, what operation do I do to 4 to end up with -2?

One answer is to multiply 4 by -1/2.

d = (-1/2)c = (-1/2)(4i) + (-1/2)(4j) = -2i - 2j

That worked. By multiplying vector c by the scalar -1/2, you end up with vector d.

Answer:

x = y = 102.5°

Step-by-step explanation:

x and y are congruent.

the sum of the 4 angles in a kite = 360°

subtract the 2 given angles from 360°

360° - 95° - 60° = 360° - 155° = 205° , then

x = y = 205° ÷ 2 = 102.5°

Answer:

YOU HAVE TO GRAPH (3,0) TO GET THE ANSWER

Step-by-step explanation:

The maximum height of the football is 15.21 yards.

The maximum height is the vertex of the parabola, when the parabola faces down.

Given

The path of a football kicked by a field goal kicker can be modeled by the equation y = -0.04x^2 + 1.56x.

Where x is the horizontal distance in yards and y is the corresponding height in yards.

The x- coordinate of the vertex is given by;

[tex]\rm x=\dfrac{-b}{2a}[/tex]

The value of b is 1.56, and a is -0.04.

Substitute all the values in the equation

[tex]\rm x=\dfrac{-b}{2a}\\\\x=\dfrac{-1.56}{-0.08}\\\\x=19.5[/tex]

Substitute the value of x in the given equation

[tex]\rm y = -0.04x^2 + 1.56x\\\\ y = -0.04(19.5)^2+1.56(19.5)\\\\y = - 15.21 + 30.42 \\\\ y=15.21 \ yd[/tex]

Hence, the maximum height of the football is 15.21 yards.
