find the coordinates of the point 3/10 of the way from a to b. a= (-3, -5) b = (10, 7)

Answer:

x = 300°

Step-by-step explanation:

If m and n are parallel, then m∠4x is equal to 120, since they are congruent angles.

Solve for x:

4x = 1200

Divide both sides by four

x = 300

Answer: The answer is C. You start off by first thinking about your slope equation, being y=Mx+b. Remember b equals your y- intercept. In this case one of your y-intercepts is positive 1 and the other is positive 2. Now you have the “b” part of the equation. Looking for slope or your “mx” part of the equation is next. All this is going to be is the rise over the run from your y intercept. How much did you rise and how much did you run to get to the next point. Both of these slopes are going up therefore both slopes will be positives. For the first one it rises 2 and runs 1 to get to the next point, however you do not need to write the one at the bottom of the 2 and can leave it as “2x+1”, because it is shaded below the red line the inequality will be less than or equal to

. The blue slope rises 1 and runs 2, it is written as

and because it is shaded above the blue one it will be greater than or equal to

.

Step-by-step explanation:

Considering the linear functions on the graph, the inequality that matches the situation is:

B. y ≥ x/2 + 2

   y ≤ 2x + 1

A linear function is modeled by:

y = mx + b, In which: m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

here, we have,

The lower bound of the interval is a linear function with

y-intercept of b = 2,

that also passes through (2,3), hence the slope is:

m = (3 - 2)/(2 - 0)

   = 1/2.

Hence the inequality is:

y ≥ x/2 + 2

The upper bound of the interval is a linear function with y-intercept of b = 1, that also passes through (2,5), hence the slope is:

m = (5 - 1)/(2 - 0) = 2.

Hence the inequality is:

y ≤ 2x + 1

The surface area of the sphere is 84453.44 yards².

We are given that:

the ride goes around the widest circle of the sphere whose circumference is =  514.96 yard.

The widest circle of the sphere is the plane contains the sphere's center

The circumference of the widest circle is:

C = 2 π r

where r is radius of the sphere.

The surface area of the sphere is defined as:

A = 4 π r²

where  r is radius of the sphere.

So, we get that:

514.96 =2 π r

514.96= 2 × 3.14 × r

r = 514.96 ÷ (2 × 3.14)

r = 514.96 ÷ 6.28

Surface Area A = 4 π r²

A = 4 × 3.14 × (514.96 ÷ 6.28) × (514.96÷ 6.28)

A = 84453.44 yards²

Therefore, we get that, the surface area of the sphere is 84453.44 yards².

Answer:

1 + 2 = 3

2 + 3 = 5

3 + 4 = 7

4 + 5 = 9

5 + 6 = 11

Step-by-step explanation:

The directed number suggested by the following will be:

A 14 degrees below zero = -14°

B altitude 200 metres = +200

It should be noted that the directed number simply means the numbers that had both size and direction. It should be noted that the direction can either be positive or negative.

A measurement of altitude or height is the distance between a location or item and a reference datum, typically in the vertical or "up" direction. Although the term "altitude" is frequently used to refer to a location's height above sea level, the term "elevation" is frequently preferred in the context of geography. The term "depth" often refers to vertical distance measurements taken in the "down" direction. Globally, the research team discovered that the pace of temperature change frequently quickens as altitude increases.

Therefore, the directed number suggested by 14 degrees below zero will be negative 14 and this will be -14°

Also, altitude 200 metres will be positive 200 and this will be +200

Using the z-distribution, the 95% confidence interval for the proportion of unsatisfactory meals is given by:

(0.0553, 0.0647).

A confidence interval of proportions is given by the following rule:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The estimate and the sample size of the interval are given as follows:

[tex]\pi = \frac{600}{10000} = 0.06, n = 10000[/tex]

The lower bound of the interval is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.06 - 1.96\sqrt{\frac{0.06(0.94)}{10000}} = 0.0553[/tex]

The upper bound of the interval is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.06 + 1.96\sqrt{\frac{0.06(0.94)}{10000}} = 0.0647[/tex]

As, there is a constant increase in the number of who are visiting the museum in August each day that is 20 people, the mean will also increase by the same number that is 20 and will be:

Mean number of people per day visiting in August = 160 + 20

Answer:

I'm guessing the whole question is: "A car drives 283.5 miles in 4.5 hours. Assuming that the distance traveled directly with the time traveled, how far will the car travel in 7 hours?"

Step-by-step explanation:

If so, here's the answer:

441 miles will be traveled in 7 hours

You could find the speed in mph

To do that, divide 283.5 by 4.5 which gives us 63

because [tex]\frac{283.5 miles}{4.5 hours}[/tex] divide to get the 4.5 hours into 1 hour so, [tex]\frac{283.5/4.5}{1}[/tex]

63 mph times 7 hours = 441

In mathematics, an operation is a function that transforms 0-n operands or parameters into a known output value. The number of operands affects how complicated the operation is. 90.95 feet per second equates to 62 miles per hour.

An operation in mathematics is the function that converts 0–n parameters or operands into definite output value. The complexity of operation depends on how many operands there are.

The operations that are the most frequently studied are binary operations (i.e., operations of the arity 2), which include addition and multiplication, and the unary operations (i.e., operations of the arity 1), which include additive inverse and the multiplicative inverse. A zero-arity operation, also known as nullary operation, is a constant. An illustration of ternary operation, also known as an operation of arity 3, is the mixed product.

Usually, it is considered that arity is constrained. Even so, the infinitary operations are occasionally considered, in which case "normal" finite dimensionality operations are referred to as finiteary operations.

A partial operation is described as being similar to operation but using a partial function in place of a function.

1miles/hour= 1.467feet/second

In the question ,

a rectangle QRST with coordinates Q(-8,5), R(-8,7), S(-5,7), and T(-5,5) is given ,

and to dilate the rectangle by a scale factor of 4 with center of dilation at the origin , we multiply coordinates of the original shape with the dilation factor

so the rule to describe the dilation will be

(x,y)→(4x,4y)

Using this rule to find the new coordinates of the rectangle Q'R'S'T' .

When Q = (-8,5)

Q' = (4*(-8),4*5)

Q' = (-32,20)

When R = (-8,7)

R' = (4*(-8),4*7)

R' = (-32,28)

When S = (-5,7)

S' = (4*(-5),4*7)

S' = (-20,28)

When T= (-5,5)

T'  = (4*(-5),4*5)

T' = (-20,20)

So the coordinates of the rectangle Q'R'S'T' is Q' = (-32,20) , R' = (-32,28) , S' = (-20,28) , T' = (-20,20) .

The Distance between line ℓ and the point j (-5,-1) is 8units.

The distance between a point PP and a line LL is the shortest distance between PP and LL; it is the minimum length required to move from point PP to a point on LL. In fact, this path of minimum length can be shown to be a line segment perpendicular to LL. The distance d can then be defined as the length of the line segment that has PP as an endpoint and is perpendicular to LL.

We know that the distance d between a point (x1,y1) and a line having equation in form of ax+by+c=0 can be expressed as,

[tex]d = \frac{|ax1+by1+c|}{\sqrt{(a^2+b^2)} }[/tex]

So, we have given that equation of line

y = 7

y-7=0

Point j = (-5,-1)

So, Distance between point j and line = d

d = [tex]\frac{|0(-5)+1(-1)-7|}{\sqrt{(0^2+1^2)} }[/tex]
