15. What is the value of x in the figure bellow?

Answer:

the answer is 3.9 km/h southeast

Step-by-step explanation:

The perpendicular line *always* has a slope of the negative reciprocal. Your given line has a slope of -5, so the perpendicular slope is -1/(-5) = 1/5.

Use the point-slope form of a general line to find the equation.

(y - y_1) = m * (x - x_1)

y - 7 = (1/5) * (x - 15)

Answer:

the answer is D (27 + 4.5 ) + 1.5

Amswer is A

Step-by-step explanation:

The increase rate per year is 0.

Calculus is a branch οf mathematics that deals with the study οf rates οf change and hοw things change οver time. It has twο main branches, differential calculus which studies instantaneοus rates οf change, and integral calculus which deals with accumulatiοn and area.

here given equatiοn fοr the value οf the cοmic bοοk is:

V(y) = 0.20y + 1.50

where y is the number οf years since it was released.

Tο find the rate οf increase per year fοr the value οf the cοmic bοοk, we can take the derivative οf V(y) with respect tο y:

dV/dy = 0.20

This means that the value οf the cοmic bοοk increases by 0.20 dοllars per year.

Tο find the rate οf increase per year fοr the initial value οf the cοmic bοοk, we need tο lοοk at the y-intercept οf the equatiοn fοr V(y). The y-intercept is the value οf V when y is 0, which is:

V(0) = 0.20(0) + 1.50 = 1.50

Therefοre, the initial value οf the cοmic bοοk is $1.50.

Tο find the rate οf increase per year fοr the initial value, we can calculate the derivative οf the initial value with respect tο y, which is:

d/dy (1.50) = 0

This means that the initial value οf the cοmic bοοk dοes nοt change with respect tο time, sο its rate οf increase per year is 0.

Answer:

Budget A

Step-by-step explanation:

Total monthly budget is;

T = Rent cost + Personal Items cost + Entertainment cost +Savings cost

For budget A;

T_A = $200 + $120 + $100 + $250

T_A = $670

For budget B:

T_B = $200 + $120 + $300 + $50 = $670

Foe budget C;

T_C = $200 + $120 + $200 + $150

T_C = $670

For budget D;

T_D = $200 + $120 + $325 + $25 = $670

We can see the total budget for all is $670.

Her rent and personal expenses have fixed amounts. Thus, the only ones that can vary are Entertainment cost and Savings cost.

Now, in all the budgets, budget A has the highest savings which is $250.

Thus, we can say it's the best budget to help her meet her goals as it still provides $100 for even entertainment which she loves with her friends.

Answer:

budget A

Answer:

<5 = 105 degrees

Step-by-step explanation:

From the description given, since line l is parallel to m then <4 is alternate to <5 and two alternate angles are equal, if thst is the case

<4 = <5 (alternate angle)

Since <4 = 105 degrees, hence m<5 = 105 degrees

Answer:

Rotate it 90°

Step-by-step explanation:

First graph D(-3, -10)

And a rotation of 90° clockwise is when you move the shape to the left 90°.

And that’s it

Answer:

I have a set of rules that should help you:

When rotating a point or shape 90 degrees counterclockwise switch the x and y values of that point and then change the sign (negative or positive) of the new x value. When rotating 90 degrees clockwise switch the x and y values of that point and then change the sign of the new y value. Finally when rotating 180 degrees just change the sign of both points to get your new value. Keep in mind that these rules only work when rotating around the origin which is (0,0)

IN this case, your point is -3, -10 and since we rotate it 90 degrees clockwise we just switch the x and y so it is now -10, -3 and then change the sign of the y which makes your final answer  -10, 3

4/968   how many times does 4 go into 9?  2 times put the 2 above the 9

 8            4 times 2 equals 8 so you put the 8 below the 9 and subtract

  1 6                   9 minus 8 equals 1 than you drop the 6

  1 6          how many times does 4 go into 16? 4 times. put the  4 above the 6

    0 8        than multiply 4 *4 =16 than 16-16=0 drop the 8

Answer:

the answer 117

Step-by-step explanation:

The 234 divided by 2 is 117.

To calculate 234 divided by 2, we perform the division operation step by step.

Step 1: Divide 234 by 2.

234 ÷ 2 = 117

The result of 234 divided by 2 is 117. When you divide 234 by 2, you are essentially dividing 234 into two equal parts. Each part contains 117. This can be confirmed by performing the calculation:

234 ÷ 2 = 117

Therefore, 234 divided by 2 is 117. Division is the inverse operation of multiplication, and in this case, we find that 234 is evenly divisible by 2, resulting in a whole number quotient of 117.

Answer:

85

Step-by-step explanation:

The sum of the measures of the interior angles of a triangle is 180 deg.

x + 52 + 43 = 180

x + 95 = 180

x = 85

Answer: 85

The angles in a triangle add up to 180 degrees

180 - 52 - 43 = 85

Answer:

  30 miles

Step-by-step explanation:

The Law of Sines is used for this purpose. The angle at R is the difference ...

  180° -(23° +34°) = 123°

Then the length r satisfies ...

  ST/sin(R) = RT/sin(S)

  ST/sin(123°) = (20 mi)/sin(34°)

  ST = (20 mi)sin(123°)/sin(34°) ≈ 30.00 mi

The length of r or ST is 30 miles.

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

<c & <f would be alternate interior angles because they're a pair of angles on the inner side of each of those two parallel lines but on opposite sides of the transversal.

Use the quadratic formula where -15 = a, 7 = b, 23 = c:  [tex]\frac{-b +- \sqrt{b^2 - 4ac}}{2a}[/tex]

Plug in the values: [tex]\frac{-7 +- \sqrt{7^2 - 4(-15)(23)}}{2(-15)}[/tex]

And get: [tex]\frac{-7 +- \sqrt{49 +1380}}{-30}[/tex]

Which simplifies to: [tex]\frac{-7 +- \sqrt{1429}}{-30} = (-7 + 37.8021163)/-30 OR (-7 - 37.8021163)/-30 = 30.8021163/30 OR -44.8021163/30[/tex]

Those are approximately 1 and -1.5
