Answer:

the anwers is b= 3/2 And yeah that's you're anwers

Answer:

(1,0)

Step-by-step explanation:

Hi there!

We're given the equation of the line as 2y+3x=3, and we want to find the x intercept of the line.

The x intercept is the coordinate point at which the line passes through the x axis. Therefore, the value of y at the x intercept will be 0.

So we can substitute 0 as y in 2y+3x=3; we'll only have x left if we do this to solve for the x intercept.

2(0)+3x=3

multiply

3x=3

divide both sides by 3

x=1

so the x intercept is 1; as a point it's (1,0)

Answer:

c = $30 + $0.75p

Step-by-step explanation:

total cost = total fixed cost + total variable cost

total fixed cost = $30

Fixed costs are costs that do not vary with output.

total variable cost = variable cost per unit x total unit

p x 0.75

Variable costs are costs that vary with production

Answer:

a) 8/20 = 8 is the total of the girls and 20 is the total of the kids

b)2/20 = 2 is the total of girls that are left handed and 20 is the total of the kids

Answer:

0.62

Step-by-step explanation:

it is because the number of girls in the class is larger than the number of boys in the class which means the probability is high

The probability of picking a girl is 0.55.

'Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.'

According to the given problem,

Number of boys = 13

Number of girls = 16

Total number of students = 13 + 16

                                          = 29

Probability = [tex]\frac{Favorable events}{Total number of events}[/tex]

                  = [tex]\frac{16}{29}[/tex]

                  = 0.55

Hence, we can conclude, the probability of picking a girl is 0.55.

Answer:

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 2, 2 ] , then

f(b) = f(2) = 2(2)² + 2 + 5 = 8 + 2 + 5 = 15

f(a) = f(- 2) = 2(- 2)² + (- 2) + 5 = 8 - 2 + 5 = 11 , then

average rate of change = [tex]\frac{15-11}{2-(-2)}[/tex] = [tex]\frac{4}{4}[/tex] = 1 → C

Answer:

[tex]g(x) = (x - 2)^2 + 1[/tex]

Step-by-step explanation:

Given

[tex]f(x) = x^2[/tex]

Required

Determine g(x)

f(x) represents the parent function. And from the graph, we have:

[tex]f(x) = x^2[/tex]

f(x) is first shifted 2 units right.

The rule is:

[tex]f'(x) = f(x - 2)[/tex]

So, we have:

[tex]f'(x) = (x - 2)^2[/tex]

Next, f'(x) is shifted 1 unit up to give g(x), the blue graph.

The rule to this is:

[tex]g(x) = f'(x) + 1[/tex]

[tex]g(x) = (x - 2)^2 + 1[/tex]

Answer:

x = 7

Step-by-step explanation:

5x - 10 = 25

shift -10 to the other side then -10 become plus 10

5x = 25 + 10

now do addition in right hand side

5x = 35

shift 5 to right hand side . 5 divides 35 because in multiplication when u shift number or variables to other side it changes to division)

x = 35/5

x = 7

The solution to the equation 5x - 10 = 25 is x = 7.

To solve the equation 5x - 10 = 25, we want to isolate the variable 'x' on one side of the equation.

First, we can start by getting rid of the constant term on the left side of the equation. We do this by adding 10 to both sides:

5x - 10 + 10 = 25 + 10

This simplifies to:

5x = 35

Next, we want to isolate 'x' by dividing both sides of the equation by the coefficient of 'x', which is 5:

5x/5 = 35/5

This yields:

x = 7

Therefore, the solution to the equation 5x - 10 = 25 is x = 7. We can verify this by substituting x = 7 back into the original equation:

5(7) - 10 = 25

35 - 10 = 25

25 = 25

Since the equation holds true, we can conclude that x = 7 is the solution.

The function f(x) = x³ after translation becomes g(x) = x³ - 4.

A function is a relation between a dependent and independent variable. We can write the examples of function as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is the function f(x) = x³ and its transformed graph as shown in the image.

The function f(x) is translated downwards. This is called downward translation. Assume that the function f(x) after the translation becomes g(x). The function f(x) = x³ passes through the origin. After translation, all the {y} - coordinates will be shifted in the downward direction by 4 units. So, we can write the final function as -

g(x) = f(x) - 4

g(x) = x³ - 4

Therefore, the function f(x) = x³ after translation becomes g(x) = x³ - 4.

The given angle is opposite the shortest of the given sides, so there are two possible solutions.

From the law of sines, ...

  B = arcsin(b/a·sin(A)) = arcsin(9/7·sin(30°)) = arcsin(9/14)

Possible values for angle B are ...

  B = arcsin(9/14) ≈ 40.0°

Step-by-step explanation:

perimeter of a semi circle=1/2(πdiameter)

1/2(3.142×10cm)

1/2(31.42cm)

15.71cm

Answer:

15.71 cm

Step-by-step explanation:

remember the formula for the circumference of a circle but make it half since it's a semi-circle

the perimeter of a circle is diameter x pi

since

the diameter is 10 and pi is 3.142

its 10 x 3.142

and that equals

31.42

that's a FULL circle so half of that

divide it by 2

31.42/2=15.71

so the diamater of the semi-circle is 15.71

No, the point (1,-1) does not the satisfy the inequality 40x-22y<=50.

It is a type of equation in which greater than less than or equal to are used instead of only equal to.

To check whether whether a point satisfies an inequality or not we need to just put it in the inequality. So,

40x-22y<=50

40(1)-22(-1)=40+22=62

62 is not less than and not equal to 50. So it does not satisfies the inequality.

Answer:

76 degrees

Step-by-step explanation:

this special line is an angle bisected.

that means it splits the angle at its starting point in 2 halves. as these names indicate, both parts are of equal size (half of the general angle).

we know one part (2) of this split angle : 38 degrees.

the other part (1) had to be equally sized : 38 degrees.

so, the total angle at point R is the sum of both split angles:

TRS = 38+38 = 76 degrees.
