The graph of y= -4x + 7 is

Answer:

Long diagonal: 12.12 yd

Short diagonal: 7 yd.

Step-by-step explanation:

As you can see, 4 righ triangles are formed.

The larger diagonal divides the angle ∠AFM=60° into two angles of 30° each.

Then,  choose one the triangles that has the angles of 30°. The hypotenuse will be the side lenght of 7 yards, the long diagonal (D) will be twice the adjacent side and the short diagonal (d) will be twice the opposite side.

Then:

- Long diagonal:

[tex]\frac{D}{2}=7*cos(30\°)=6.06yd\\\\D=2(\frac{D}{2})=2(6.06yd)=12.12yd[/tex]

- Short diagonal:

[tex]\frac{d}{2}=7*sin(30\°)=3.5yd\\\\d=2(\frac{d}{2})=2(3.5yd)=7yd[/tex]

Answer:

The length of diagonals are 7 yd and 12.12 yd

Step-by-step explanation:

Let the point of intersection called as 'D'

<AFD = <MFD =60/2 = 30°

Then < AFM = <AFD + <MFD

Consider the ΔAFD

The angles are 30°, 60° and 90 then sides are in the ratio

1 : √3 : 2

The two diagonals are MA and FR

MA = MD + AD = 7/2 + 7/2 = 7 yd

FR = FD + RD =  7√3/2 +  7√3/2 =  7√3 = 12.12 yd

Therefore the length of diagonals are 7 yd and 12.12 yd

Answer:

  16

Step-by-step explanation:

The quotient of a number (x) and 4 is written x/4. 56 less than that is ...

  (x/4) -56

The problem statement tells us the value of this is -52, so we have ...

  (x/4) -56 = -52

Add 56 to both sides of this equation, and you get ...

  x/4 = 4

Multiply both sides of this equation by 4 and you get ...

  x = 16

The value of the unknown number is 16.

First you would need to move the variable causing it to change its sign

5x=10-y

Then divide both sides by 5

X=2-1/5y

Then you are left with your answer:

x=2-1/5y

Answer: B) Addition Property

Step-by-step explanation:

The Step 3 is: [tex]3x-30=0[/tex]

The idea is to solve the equation, which means that you have to find the value of the variable [tex]x[/tex].

As [tex]3x-30[/tex] is a subtraction, you need to add 30 to both sides of the equation to keep the equation balanced. This property is known as "Addition property of equality".

This property states that adding the same number to both sides of the equation, the equality does not change:

[tex]a=b\\a+n=b+n[/tex]

Then, the Addition property of equality applied in Step 3, get you to Step 4:

[tex]3x-30+(30)=0+(30)\\3x=30[/tex]

Answer:

x = 5.75

Step-by-step explanation:

4^(x+7) = 8^(2x-3)

But; 4^(x+7) = 2^2(x+7)

8^(2x-3) = 2^3(2x-3)

2^2(x+7) = 2^3(2x-3)

Since the bases are the same;

2(x+7) = 3(2x-3)

2x + 14 = 6x -9

14 + 9 = 6x - 2x

23 = 4x

x = 23/4

x = 5.75

Answer:

A. 5/9    B. 1/6.

Step-by-step explanation:

Total possible events = 6*6 = 36.

A.  The possible combinations for the sum  being <= 6 are:

1 ,1  2,2   3,3   1,2  1,3  1,4  1,5  2,1   2,3  2,4  3,1   3,2  3,3  4,1  4,2  5,1

= 16

So Probability of Sum > 6 =  (36-16) / 36

= 20/36

= 5/9.

B.   Possible combinations where the sum is divisible by 6  are

3,3  2,4  4,2  1,5  5,1. 6,6   =   6.

So the required probability =  6/36

= 1/6.

Answer:

B is your answer

Step-by-step explanation:

Why this is, is because it is parallel an all four sides while a trapezoid isn't parallel on all four sides. So that means that B is not a trapezoid.

Figure B is not a trapezoid

A trapezoid is a quadrilateral with at least one pair of parallel sides.

The non-parallel sides may have different lengths, and its angles can vary.

It combines characteristics of both triangles and parallelograms in its geometric properties.

Figure A represents a trapezoid cos it has a lone pair of parallel lines.

Figure B is not a trapezoid but a parallelogram because it has 2 pairs of parallel lines.

Step-by-step explanation:

Range of the graph is the ALLOWED y-values. The y-axis is number of gallons left in tank. So, it cannot be NEGATIVE number of gallons, so 0 is the lower limit of the range.

As we can see from the axis of the graph, we see where the line cuts the y-axis, that is the upper limit of number of gallons he starts off with. The y-intercept (y-axis cutting point) is 12.

So we can say that the range is  0 ≤ y ≤ 12

Answer:

  c. Reflect across the y-axis, translate 3 right and 2 down

Step-by-step explanation:

You want a description of the transformation of g(x) = ln(x) into f(x) = ln(3 -x) -2.

Reflection across the y-axis is the result of replacing x by -x in a function. That is, f(x) = g(-x) will reflect g(x) across the y-axis.

Translation right h units and up k units is the result of the transformation ...

  f(x) = g(x -h) +k

The given function f(x) can be written as ...

  f(x) = g(-(x -3)) -2

The first transformation is replacement of x by -x:

  f(x) = g(-x) . . . . . . . . reflection over the x-axis

The second transformation is replacement of x by x-3, and adding -2 to the function value:

  f(x) = g(-(x -3)) -2 . . . . translation of the reflected function right 3, down 2

The graph of g(x) = ln(x) is transformed to the graph of f(x) = ln(3 -x) -2 by reflection over the y axis, then translation right 3 and down 2, choice C.

Answer:

basketball hoop= 10 feet high

steve=5 feet tall

hes standing 12 feet away

so  i would say 3 feet away

The distance from the top of Steve's head to the hoop is 13 feet.

Given information in the question is the height of basketball hoop is 10 feet, height of Steve 5 feet and the distance from hoop to him is 12 feet.

Therefore the distance from the top of Steve's head to the hoop is also 12 feet.

Also the distance from the top of Steve's head and the top of Hoop is (10 - 5) feet = 5 feet.

Therefore calculating the distance from top of Steve's head to the hoop by using Pythagoras Theorem -

Let the required distance is d feet .

Answer:

Step-by-step explanation:

There would be 216 outcomes because

6*6=36 outcomes so

6*6*6, or 36*6, = 216.

When 3 fair dice are rolled then there are 216 possible outcomes.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

When 2 fair dice are rolled there are 36 possible outcomes.

Now,

Since, When 2 fair dice are rolled then possible outcomes = 6 x 6 = 36

So, When 3 fair dice are rolled then possible outcomes = 6 x 6 x 6

                                                                                      = 216

The measure of each angle is [tex]20\°[/tex]

Step-by-step explanation:

see the attached figure to better understand the problem

Let

x------> the angle on each side

we know that

[tex]x\°+140\°+x\°=180\°[/tex]

solve for x

[tex]2x\°=180\°-140\°[/tex]

[tex]2x\°=40\°[/tex]

[tex]x=20\°[/tex]

x = 4.8

With angles like this these ones, the 2 lines equal the same amount. To find the length of one of the lines, you multiply the given lengths.

So, for the first angle, the line with both angles has a 4 and 6, so the length of the line is 24.

Since the lines are equal, to find the length of x you take 24 and divide it by 5, which gives you 4.8, or 24/5.

This means x = 4.8.

To double check, you can simply multiply 4 and 6, then 5 and 4.8. If the answers are the same, it is correct.

This applies to all 3 angles shown.
