Find the perimeter of triangle ABC. Round your answer to two decimal places.

(9,-2) (5,1) (9,-3)

The next two numbers on the number pattern are given as follows:

A 12.2, 12.9.

To obtain the next two points on the number pattern, first we must identify what is the pattern.

The pattern is given as follows:

The final term is 6.1, which is obtained after the addition of 0.7 to 5.4. Double 6.1 is obtained multiplying the number by 2, as follows:

2 x 6.1 = 12.2.

Then the number obtained after 0.7 is added to 12.2 is given as follows:

0.7 + 12.2 = 12.9.

Answer: Pictures below show intersection point on the graph.

Step-by-step explanation:

Answer:

Out of 50 students in a class, 40% are girls, meaning there are 50 x 40% = 20 girls in the class.

And the number of boys is 50 - 20 = 30 students.

If 30% of the girls wear spectacles, that means 30/100 x 20 = 6 girls wear spectacles.

And the number of girls not wearing spectacles is 20 - 6 = 14.

So the total number of girls wearing spectacles is 6, and the number of boys is 30, and the number of girls not wearing spectacles is 14.

Answer:

C is irrational--6 is not a perfect square.

Answer:

5625mm²

Step-by-step explanation:

The area of a square is found by multiplying the length of one side by itself. So if each tile is a square and measures 75mm on one side, then the area of one tile is:

75mm x 75mm = 5625mm²

The equation for the function shown in the graph is y = sin(x + π/2).

The sine function in trigonometry is the ratio of the hypotenuse's length to the opposite side's length in a right-angled triangle. To determine a right triangle's unknown angle or sides, utilize the sine function.

Given a graph of a sine function,

which shows the amplitude of 1,

and value of x-intercept is π/2, when y is 0, x is π/2

the equation for sine is

y = a sin(bx)

where a is the amplitude = 1

b is π

y = sin(x),

but given x-intercept π/2,

so, y = sin(x + π/2)

Hence option A is correct.

f(x) and g(x) are inverses using composition

A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

To confirm the inverse relationship using composition.

For valid inverse f(g(x)) must be equal to g(f(x))

f(x) = ∛(x) + 13; g(x) = (x - 13)³:

f(g(x)) = f((x - 13)³)

f(g(x)) = ∛((x - 13)³) + 13

f(g(x)) = x - 13 + 13

f(g(x)) = x

g(f(x)) = g(∛(x) + 13)

g(f(x)) =  (∛(x) + 13 - 13)³

g(f(x)) =  (∛(x))³
g(f(x)) =  x

Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse

f(x) = x³ + 1; g(x) = ∛(x - 1):

f(x) = x³ + 1; g(x) = ∛(x - 1)

f(g(x)) = f(∛(x - 1))

f(g(x)) =  (∛(x - 1))³ + 1

f(g(x)) =  x - 1 + 1

f(g(x)) =  x

g(f(x)) = g(x³ + 1)

g(f(x)) = ∛((x³ + 1) - 1)

g(f(x)) = ∛(x³)

g(f(x)) = x

Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse

The two lines L1 and L2 are parallel

For two lines to be parallel the slope must be equal, hence we calculate the slope of the two lines

The slope, m of the linear function L1 is calculated using the points (–2, 9) and (1, 3)

m = (y₀ - y₁) / (x₀ - x₁)

m = (9 - 3) / (-2 - 1)

m = (6) / (-3)

m = -2

The slope, m of the linear function L2 is calculated using the points (–4, 10) and (3, –4)

m = (y₀ - y₁) / (x₀ - x₁)

m = (10 + 4) / (-4 - 3)

Answer:

1. The volume of water in the tank in cubic yards can be calculated by multiplying the length, width, and depth of the tank in feet by the conversion factor of 0.037037 yds3/ft3:

87 ft x 36 ft x 15 ft x 0.037037 yds3/ft3 = 997.78 yds3

2. To treat the water, the aquarium must purchase 998 bags of salt, as 1.1 yds3 of water requires one bag of salt.

3. The aquarium must pay $4,835.30 for the salt to treat the water in the new shark tank. This is calculated by multiplying the number of bags of salt (998) by the cost of one bag of salt ($4.85).

Points are (0,0) and (2,8).

What is the gradient?

The vector field f's value at a point p in the vector calculus is the "direction and rate of fastest increase" for a scalar-valued differentiable function f with many variables.

Here, we have

Given: y = 4x

The number in front of the x is the gradient (slope). This number represents the amount of up or down for a given amount of long.

If the number in front of the x (coefficient) is positive the 'slope' goes up. If the coefficient is negative it means the 'slope' is down.

Now, substitute any value you chose into x, multiply it by 4 and you have your value for y

Let x = 0,

y = 4(0) = 0

So this can be our first point on the graph.

(x₁, y₁) ⇒ (0,0)

Let x = 2

y = 4(2) = 8

So this can be our second point on the graph.

(x₂, y₂) ⇒ (2,8)

Now, we draw a line through them extending it to the edges of the axis.

The compound inequality for the graph given is  -2 < x < 5.

When a compound inequality is graphed such that there is an open circle instead of a filled - in circle over a number, then it means that x is either greater than this value, or less than this value. In other words, x is not equal to this value.

The circles over - 2 and 5 are not filled in which means that x is greater or less than - 2 and 5.

x is less than 5 because the arrow goes from 5 to infinity and x is greater than - 2 for the same reason.

The compound inequality is therefore:

The velocity of the ball when it returns to the ground is -8 m/s

An equation is an expression composed of variables and numbers linked together by mathematical operations.

The distance of a ball thrown upward is given by:

h(t) = -2t² + 12t - 10

The ball hits ground when h(t) = 0, hence:

-2t² + 12t - 10 = 0

t = 5 or 1

The velocity (V) of the ball is:

V = dh/dt

V = (d/dt)(-2t² + 12t - 10) = -4t + 12

V = -4t + 12

The ball hits ground when t = 5 or 1 s, hence:

V(1) = -4(1) + 12 = 8 m/s

V(5) = -4(5) + 12 = -8

In this problem we have the coordinates of an endpoint in a line segment and the midpoint of that segment, that is, the point in the line segment that partitions it into two parts of equal length. The formula needed to find the coordinates of the missing endpoint is:

0.5 · P1(x, y) + 0.5 · P2(x, y) = M(x, y)

Where:

If we know that P1(x, y) = (- 6, 4) and M(x, y) = (- 5, 6), then the coordinates of the other endpoint are:

0.5 · P1(x, y) + 0.5 · P2(x, y) = M(x, y)

0.5 · (- 6, 4) + 0.5 · P2(x, y) = (- 5, 6)

(- 3, 2) + 0.5 · P2(x, y) = (- 5, 6)

The simplified ratio of miles to gallons is 14:1. The solution has been obtained by using the concept of ratios.

What are ratios?

A ratio is a comparison or condensed version of two identical values. The reciprocity of this relationship tells us how many times one quantity is equal to the other. To put it simply, a ratio is a number that can be used to represent one thing as a percentage of another.

We are given the distance to be 189 miles and the volume of gas 13[tex]\frac{1}{2}[/tex] gallons.

So, in order to find the ratio of miles to gallons, we need to divide 189 miles onto 13[tex]\frac{1}{2}[/tex] gallons of gas.

We get

189/13.5 = 14

Answer:

the expression "square root of 1+3a/25" makes sense for all values of a that are greater than or equal to -8.333.

Step-by-step explanation:

The square root of a number is only defined for non-negative values of that number. Therefore, for the expression "square root of 1+3a/25" to make sense, the value inside the square root must be non-negative.

1+3a/25 >= 0

This inequality can be rearranged to get the values of a for which the expression makes sense.

3a/25 >= -1

3a >= -25

a >= -25*3/3

a >= -25/3

a >= -8.333

Therefore, the expression "square root of 1+3a/25" makes sense for all values of a that are greater than or equal to -8.333.

The perimeter of polygon ABC = 67.4

The perimeter of polygon PQRS = 78.8

The perimeter of a polygon is calculated by adding the lengths of all sides of the polygon together.

The Two-Tangent Theorem states that if two tangents are drawn to a circle from the same external point, then the tangents are congruent (have the same length).

Perimeter of polygon ABC = AB + BC + AC

AB = 10.5 + (23.2 - 11.2) = 22.5 [based on the Two-Tangent Theorem]

BC = 23.2

AC = 10.5 + 11.2 = 21.7

Perimeter of polygon ABC = 22.5 + 23.2 + 21.7 = 67.4

Perimeter of polygon PQRS = PQ + QR + RS + PS

PQ = 25

PS = 21.8

QR = 13 + 4.6 = 17.6
