Answer:

in the last one 3+4+4×15=67

in the first if we see there are three shapes if we divide 45/3 so the value of each shape is 15

in the second there are two bananas and one shape as we know the value of shape so 23-15=8 as there are two bananas so the value of each banana is 4

in the third there are two clocks and one banana as we know the value of banana so 10-4=6 as there are two clocks so the value of each clock is 3

from above

shape=15 banana=4 and clock =3 pitting in the equation gives us the value of 67

Answer:

The x-intercept is the location on the graph when the output is 0.

f(x) > 0 is intervals of the domain where the graph is above the x-axis.

y-intercept is the location on the graph when the input is 0.

f(x) < 0 is intervals of the domain where the graph is below the x-axis.

Answer:

√(r+n)/5=m

Step-by-step explanation:

r=5m²-n

adding n on both sides

r+n=5m²-n+n

r+n/5=m²

taking square root on both sides

√(r+n)/5=m

Answer:

337/100 or 3 37/100

Step-by-step explanation:

This is pretty self-explanatory, it just involves a bit of thinking.

The recommended daily value will be 100% or 100/100.

So, if the cup of cooked spinach contains 377% of the recommended daily value, then it will be 377/100.

Answer:

the fifth number is 70

Step-by-step explanation:

mean (average) of first 5 numbers =50 , Then sum of this 5 numbers = 50*5 =250.

The mean  of 4 numbers = 45 . Sum 4 numbers = 45*4 = 180

the fifth number is 250-180=70

(180 +70)/5=50 which is the mean

Answer:

According to the given statement Jewels has $6.75 to ride the ferry around Connecticut. It will cost her $0.45 every time she rides.

It means that if she rides a ferry, she pays

If she does not ride the ferry she won't pay

This shows that the paying depends on riding.

Thus riding is independent variable and cost is dependent....

Answer:

In the diagram, planes JMN and KLO are parallel and planes JKN and LMP are also parallel.

Step-by-step explanation:

To be parallel in geometric terms means that two planes are on opposite sides of each other and will never intersect or touch. Knowing this, we can go through the choices one by one to see if those planes are parallel.

LMP and JKL are not parallel because they intersect at point L.

JMN and JKL are not parallel because they intersect at point J.

JKN and LMP are parallel because they never intersect or touch.

JMN and KLO are parallel because they never intersect or touch.

So, planes JMN and KLO are parallel and planes JKN and LMP are also parallel.

Answer:

  f(x) = -x^2 +8x -16

Step-by-step explanation:

With the given data, we can write the factored function as ...

  f(x) = -1(x -4)^2 . . . . . -1 is the leading coefficient; exponent of 2 gives root multiplicity

  f(x) = -x^2 +8x -16

The graph which shows the solution to the system of linear inequalities is given below.

Suppose there is inequality given as: y ≥ f(x)

The region it covers is the region of value pairs (x,y) for which this inequality holds true.

We've to draw the region covered by it.

For a function y = f(x), there is y > f(x) on one side of the graph of the function y = f(x) in XY plane, and on other side there is y < f(x).

We just need to figure out this fact at 1 point on either side of the graph of the function y = f(x) , and then the area where y > f(x) is true, along with the curve of the function y = f(x) is included in the region covered by inequality y ≥ f(x)

We are given that;

The system of linear inequalities x + 5y < 25 and y > 2x + 4

Now,

We would need to graph the two inequalities on the same coordinate plane and shade in the region that satisfies both inequalities.

The first inequality, x + 5y < 25, can be graphed by first graphing the line x + 5y = 25 (by solving for y, y = (25 - x)/5 = 5 - (1/5)x) and then shading in the region below the line.

The second inequality, y > 2x + 4, can be graphed by first graphing the line y = 2x + 4 and then shading in the region above the line.

The solution to the system of linear inequalities is the region that satisfies both inequalities, which is the shaded region that is below the line x + 5y = 25 and above the line y = 2x + 4.

Therefore, by the given inequalities the answer will be given below

Answer:

The maximum value of (2·x - 10) is 20

Step-by-step explanation:

Given that the maximum value of f(x) = 20

f(x) = -4·x² + bx + c

We are required to find the maximum value of (2·x - 10)

f'(x) = -8·x + b = 0

x = b/8

f''(x) = -8, therefore, f'(x) is the maximum point

20 = -4·x² +8·x²  + c

20 = -4·(b/8)² + b×(b/8) + c

20 = -b²/16 + b²/8 + c

20 = b²/16 + c

f(2·x - 10) = -4·(2·x - 10)² + b·(2·x - 10) + c

f(2·x - 10) = b·(2·x - 10) + c - (16·x²-160·x +400

Differentiating to find the maximum gives;

f'(2·x - 10) = d(b·(2·x - 10) + c - (16·x²-160·x +400)/dx = 2·b -32·x +160 = 0

x = (2·b +160)/32 = 0.0625·b +5

At the maximum point, therefore, we have;

b·(2·(0.0625·b +5) - 10) + c - (16·(0.0625·b +5)²-160·(0.0625·b +5) +400

At the max value of f(2·x - 10) = b²/16 + c

Since b²/16 + c = 20, we have the maximum value of (2·x - 10) = 20.

Answer:

Option (2)

Step-by-step explanation:

Let the equation of the line is,

y - y' = m(x - x')

where (x', y') is a point lying on the given line.

And m = slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Line given in the graph passes through two points (-5, -1) and (-2, -3).

Slope of the line 'm' = [tex]\frac{-3+1}{-2+5}[/tex]

                                 = [tex]-\frac{2}{3}[/tex]

Therefore, equation of the line passing through(-5, -1) and slope of the line = [tex]-\frac{2}{3}[/tex] will be,

y - (-1) = [tex]-\frac{2}{3}[x-(-5)][/tex]

[tex]y+1=-\frac{2}{3}(x+5)[/tex]

[tex]y=-\frac{2}{3}x-\frac{10}{3}-1[/tex]

Answer:

0.4

Step-by-step explanation:

That is the answer.......

===================================================

Explanation:

Define the two events as such

A = event of chosen to be in the play

B = event of getting the lead role

The probability of getting chosen in the play is 0.5, so P(A) = 0.5

Because getting a lead role means you must have been selected for the play, this means that event B depends entirely on event A. We can say

P(A and B) = 0.2

which is the same as P(B and A)

Therefore the conditional probability is

P(B given A) = P(B and A)/P(A)

P(B given A) = 0.2/0.5

P(B given A) = 2/5

P(B given A) = 0.4

You can replace each "given" with a vertical line to write P(B | A) instead of "P(B given A)". I used "given" because the vertical line could be easily mistaken for an uppercase letter i or a lowercase letter L.

Answer:

D

Step-by-step explanation:

Recall that:

[tex]\displaystyle \cos\theta = \frac{1}{\sec\theta}[/tex]

Since we are given that secθ = -7.3, then by definition:

[tex]\displaystyle \cos\theta = \frac{1}{(-7.3)}\approx -0.14[/tex]

Next, recall that:

[tex]\displaystyle \sin\left (\frac{\pi}{2} - \theta \right) = \cos\theta[/tex]

This is the co-function identity.

And since sine is an odd function:

[tex]\sin u = -\sin (-u)[/tex]

In other words:

[tex]\displaystyle \sin\left (\frac{\pi}{2} - \theta \right) = -\sin\left(\theta - \frac{\pi}{2}\right)= \cos\theta[/tex]

Therefore:

[tex]\displaystyle \sin\left(\theta - \frac{\pi}{2}\right) = -\cos\theta = -(-0.14) = 0.14[/tex]

Hence, our answer is D.

Answer:

r

Step-by-step explanation:

Since r is not given, the length we can be find using the Law of Sines using is length r.

The Sine formula or the Law of Sines

q/Sine Q = r/Sine R

q=9.5

r is the unknown

9.5/Sine 18° = r/ Sine 135°

With sine law length of the side opposite to the angle in a triangle can be determined i.e. r = 21.738.

∠Q measures 18°, ∠R measures 135°, and q equals 9.5, then which length can be found using the Law of Sines is to determined.

The sine formula provides the ratio of the sides and angles of a triangle. The sine rule can be explained using the expression, a/sinα = b/sinβ = c/sinФ. Here a, b, and c are the measures of the sides of the triangle, and α, β, Ф are the angles of the triangle.

Here,

sine law for given numerical,
[tex]q/sinQ = r/sinR[/tex]
Q = 18°, R = 135° and q =9.5
⇒ 9.5/sin18 = r/sin135
    30.24 * sin135 = r
     r = 21.738

Thus, with sine law, length of the side opposite to the angle in a triangle can be determined i.e. r = 21.738.
