The general equation for a circle is

[tex] {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} [/tex]

where (h, k) is the coordinates of the center of the circle and r is the radius. Since the circle passes through (4, 4) and (-4, -4), its center is located at the origin, which means its equation becomes

[tex] {x}^{2} + {y}^{2} = {4}^{2} [/tex]

Answer:

615.75

Step-by-step explanation:

The surface area of this sphere is 615.44 cm² Round to the nearest tenth.

The surface area of a sphere is the total area that is covered by its outer surface. The surface area of a sphere is always expressed in square units. A sphere is a three-dimensional shape analouge of a circle.

The area of a sphere = 4πr^2

here, we have,

To calculate the area of a sphere.

We have as data:

Radius (r) = 7cm

Pi(π) = 3.14

The formula to calculate the area of a sphere is:

S.A. = 4nr²

V = πr³

Substituting values into the equation.

S.A. = 4 (3.14) (7)²

S.A = 615.44 cm²

Hence, the surface area of this sphere is 615.44 cm² Round to the nearest tenth.

The average speed on Monday is 27mph

Step-by-step explanation:

Given

Let:

[tex]1\to Sunday[/tex]

[tex]2\to Monday[/tex]

So:

[tex]t_1 = 5.4hr[/tex]

[tex]t_2 = 6hr[/tex]

[tex]s_2 = s_1 - 3[/tex] ---- average speed slower on Monday than Tuesday

Required

The average speed on Monday

Average speed is calculated as:

[tex]Speed = \frac{Distance}{Time}[/tex]

[tex]s = \frac{d}{t}[/tex]

Make d the subject

[tex]d = st[/tex]

On Sunday, we have:

[tex]d = s_1t_1[/tex]

[tex]d = s_1 * 5.4[/tex]

On Monday, we have:

[tex]d = s_2t_2[/tex]

[tex]d = s_2 * 6[/tex]

The distance traveled is constant;

So:

[tex]s_1 * 5.4 = s_2 * 6[/tex]

Make s1 the subject in: [tex]s_2 = s_1 - 3[/tex]

[tex]s_1=3+s_2[/tex]

So, we have:

[tex](3 + s_2) * 5.4 = s_2 * 6[/tex]

Open bracket

[tex]16.2 + 5.4s_2 = 6s_2[/tex]

Collect like terms

[tex]6s_2 - 5.4s_2 = 16.2[/tex]

[tex]0.6s_2 = 16.2[/tex]

Solve for s_2

[tex]s_2 = 16.2/0.6[/tex]

[tex]s_2 = 27[/tex]

The average speed on Monday is 27mph

Answer:

The probability that you win at least $1 both times is 0.25 = 25%.

Step-by-step explanation:

For each game, there are only two possible outcomes. Either you win at least $1, or you do not. Games are independent. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Probability of winning at least $1 on a single game:

The die has 6 sides.

If it lands on 4, 5 or 6(either of the three sides), you win at least $1. So

[tex]p = \frac{1}{2} = 0.5[/tex]

You are going to play the game twice.

This means that [tex]n = 2[/tex]

The probability that you win at least $1 both times is

This is P(X = 2).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{2,2}.(0.5)^{2}.(0.5)^{2} = 0.25[/tex]

The probability that you win at least $1 both times is 0.25 = 25%.

The probability that you win at least $ 1 both times is 25%.

Since in a particular game, a fair die is tossed, and if the number of spots showing is either four or five, you win $ 1, while if the number of spots showing is six, you win $ 4, and if the number of spots showing is one, two, or three, you win nothing, and you are going to play the game twice, to determine the probability that you win at least $ 1 both times the following calculation must be performed:

Therefore, the probability that you win at least $ 1 both times is 25%.

Answer: 60 days

Step-by-step explanation:

To get the number of days that both of them will be washing the cars on thesame day, we have to find the lowest common multiple of 15 and 20. This will be:

Multiple of 15 = 15, 30, 45, 60, 75, 90

Multiples of 20 = 20, 40, 60, 80, 100

Lowest common multiple = 60

Therefore, they'll be Washing the car on thesame day on the 60th day.

What is the measurement?

Measurement is the process of finding a number that shows the amount of something. Time the ongoing sequence of events is time. We can measure time in seconds, minutes, hours, days, weeks, months, and years.

Here given that,

The club will base its decision about whether to increase the budget for the indoor rock climbing facility on

the analysis of its usage. The decision to increase the budget will depend on whether members are using

the indoor facility at least two times a week. Use the best measure of center for both of the original data

sets to determine whether the club should increase the budget.

As per this we get that,

Yes, they can increase the budget, because both Manuel has [tex]8[/tex] and Gretchen [tex]9[/tex] are at least [tex]8[/tex] and [tex]8[/tex] times per month is equivalent to the two times per week.

Answer:

166.5 cm squared

Step-by-step explanation:

Multiply 11x11 =121

Multiply 7x6.5 =45.5 (we get the 7 because 18-11=7)

Then we add 121 and 45.5 and get 166.5

The area of this composite shape is 166.5 square cm

Composite figures are figures that has more than 1 shape. The given figure is made up of two rectangles.

The area of the shape is given as shown below;

Area = (11*11) + (7 * 6.5)
Area = 121 + 45.5

Area = 166.5 square cm

Answer:

see explanation

Step-by-step explanation:

(a)

Since Y is the midpoint of XZ , then

XY = YZ , that is

4a - 4 = 3a + 2 ( subtract 3a from both sides )

a - 4 = 2 ( add 4 to both sides )

a = 6

(b)

XY = 4a - 4 = 4(6) - 4 = 24 - 4 = 20

XZ = 4a - 4 + 3a + 2 = 7a - 2 = 7(6) - 2 = 42 - 2 = 40

Step-by-step explanation:

if if y is the mid point of the line

therefore: XY=YZ

4a-4=3a+2

collecting like terms.

4a-3a=2+4

a=6

b. XY= 4a-4

recall a=6

XY= 4(6)-4

XY=24-4

XY= 20

XZ= 4a-4+3a+2

XZ= 7a-2
