Which equation describes the summer for two vectors plotted below?

Answer:

6 x 2 = 8 + 11 = 19 x 3 = 57

Step-by-step explanation:

Answer: Choice D

Explanation:

The increase of 9.8% rounds to 10% when rounding to the nearest ten

An increase of 10% would use the multiplier 1.1

Think of it like saying 1 + 0.10 = 100% + 10%

Similarly, the 5.1% rounds to 5% and an increase of this amount will use the multiplier 1.05

So if we started with 20 items, then 20(1.1)(1.05) is the expression that estimates an increase of 10% followed by an increase of 5%. The order doesn't matter (so you could increase by 5% first, then 10% later).

find the DB =[tex]\displaystyle\bf \sqrt{17^2-8^2} =15[/tex]  ; now find AD=AB-DB=21-15=6  .Then                AC=[tex]\displaystyle\bf \sqrt{AD^2+CD^2} =\sqrt{6^2+8^2} =10[/tex]  

Answer:

C

Step-by-step explanation:

Using Pythagoras' identity in both right triangles

To find BD

BD² + CD² = BC²

BD² + 8² = 17²

BD² + 64 = 289 ( subtract 64 from both sides )

BD² = 225 ( take the square root of both sides )

BD = [tex]\sqrt{225}[/tex] = 15

Then

AD = AB - BD = 21 - 15 = 6

To find AC

AC² = AD² + CD²

AC² = 6² + 8² = 36 + 64 = 100 ( take the square root of both sides )

AC = [tex]\sqrt{100}[/tex] = 10 → C

According to the properties of rectangles,

The diagonals of rectangles are equal and bisect each other at 90°.

As per this,

OR = OT

[tex]2x + 4 = 3x + 1[/tex]

[tex]4 - 1 = 3x - 2x[/tex]

[tex]3 = x[/tex]

TE = 2OT

TE = 2(3x + 1)

= 6x + 2

= 18 + 2

= 20

RN = 2OR

RN = 2(2x + 4)

= 4x + 8

= 4(3) + 8

We can find the other leg of the right triangle by using the Pythagorean Theorem formula.

[tex]formula-a^2+b^2=c^2[/tex]

[tex]legs-a,b[/tex]

[tex]hypotenuse-c[/tex]

--------------------------------------------------

Remember, the legs of the triangle are the sides that form the right angle. The hypotenuse is the longest side of the triangle.

Here, I am solving for one of the legs.

[tex]16^2+b^2=34^2[/tex]

[tex]256+b^2=1156[/tex]

[tex]1156-256=900[/tex]

[tex]b^2=900[/tex]

[tex]b=30.[/tex]

--------------------------------------------------

Therefore, the length of the second leg is 30 inches.

Answer:

15

Step-by-step explanation:

to find angle C, you subtract 50 from 180 which is 130. that means then you add 35 and 130 together which is 165. then subtract 180-165 which is 15.

The measure of the angle ∠BAC of the triangle ABC will be 15°.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In triangle ABC, the angle B is 35° and the exterior angle C is 50°.

The measure of the angle ∠BAC of the triangle ABC will be,

We know that the sum of any two interior angle of the triangle is equal to the third exterior angle of the triangle.

The sum of the angles ∠BAC and ∠ABC is equal to angle ∠BCF. Then the equation will be

∠BAC + ∠ABC = ∠BCF

    ∠BAC + 35° = 50°

             ∠BAC = 50° – 35°

             ∠BAC = 15°

Thus, the measure of the angle ∠BAC will be 15°.

Answer:

x = 25°

Step-by-step explanation:

3x + 2x + x + 30° = 180°

6x + 30° = 180°

6x = 150°

x =25°

=> 3x = 25 * 3 = 75°

=> 2x = 25 * 2 = 50°

=> x + 30° = 25° + 30° = 55°

Answer:

y = −14x + 3

Step-by-step explanation:

Parallel lines have the same slope

The equation y = −14x + 7 is put in slope intercept form ( y = mx + b )

Where m = slope

-14 takes "m's" place meaning that the slope = -14

If parallel lines have the same slope than the equation of a line parallel to y = −14x + 7 must have a slope of -14

The only equation that has a slope of -14 is D

Answer:

Answer:

The terminal velocity is 8.00ft/s

Step-by-step explanation:

Given

[tex]v(t) = 1000t^2 - 5t + 8[/tex]

Required

The terminal velocity

This implies that we calculate the maximum velocity.

First, we calculate the maximum value of t using:

[tex]t_{max} = -\frac{b}{2a}[/tex]

Where:

[tex]v(t) = at^2 + bt + c[/tex]

So, we have:

[tex]t_{max} = -\frac{-5}{2*1000}[/tex]

[tex]t_{max} = \frac{5}{2000}[/tex]

[tex]t_{max} = 0.0025[/tex]

Substitute this value of t in [tex]v(t) = 1000t^2 - 5t + 8[/tex] to get the maximum velocity

[tex]v(t) = 1000t^2 - 5t + 8[/tex]

[tex]v(t) = 1000 * 0.0025^2 - 5 * 0.0025 + 8[/tex]

Using a calculator, we have:

[tex]v(t) = 7.99375[/tex]

Approximate

[tex]v_{max} = 8.00ft/s[/tex]

Velocity is the rate of change of its position with respect to time. The terminal velocity of the skydiver is 200 ft/sec.

Velocity is the rate of change of its position with respect to time.

[tex]V = \dfrac{dy}{dt}[/tex]

Given the velocity of the skydiver by the function v(t)=1000t/(5t+8), after some time, the velocity will become terminal velocity and then it can not be increased further, therefore, the terminal velocity can be written as,

[tex]\lim_{t \to \infty} V(t) = \lim_{t \to \infty} \dfrac{1000t}{5t+8}\\\\[/tex]

                    [tex]= \lim_{t \to \infty} \dfrac{\frac{1000t}{t}}{\frac{5t}{t}+\frac{8}{t}}\\\\[/tex]

                    [tex]= \dfrac{1000}{5+\frac{8}{t}}\\\\= \dfrac{1000}{5}\\\\=200[/tex]

Hence, the terminal velocity of the skydiver is 200 ft/sec. It can be confirmed by plotting the function on the graph.

Answer:

Step-by-step explanation:

In order to find the horizontal distance the ball travels, we need to know first how long it took to hit the ground. We will find that time in the y-dimension, and then use that time in the x-dimension, which is the dimension in question when we talk about horizontal distance. Here's what we know in the y-dimension:

a = -32 ft/s/s

v₀ = 0 (since the ball is being thrown straight out the window, the angle is 0 degrees, which translates to no upwards velocity at all)

Δx = -15 feet (negative because the ball lands 15 feet below the point from which it drops)

t = ?? sec.

The equation we will use is the one for displacement:

Δx = [tex]v_0t+\frac{1}{2}at^2[/tex] and filling in:

[tex]-15=(0)t+\frac{1}{2}(-32)t^2[/tex] which simplifies down to

[tex]-15=-16t^2[/tex] so

[tex]t=\sqrt{\frac{-15}{-16} }[/tex] so

t = .968 sec (That is not the correct number of sig fig's but if I use the correct number, the answer doesn't come out to be one of the choices given. So I deviate from the rules a bit here out of necessity.)

Now we use that time in the x-dimension. Here's what we know in that dimension specifically:

a = 0 (acceleration in this dimension is always 0)

v₀ = 80 ft/sec

t = .968 sec

Δx = ?? feet

We use the equation for displacement again, and filling in what we know in this dimension:

Δx = [tex](80)(.968) +(0)(.968)^2[/tex] and of course the portion of that after the plus sign goes to 0, leaving us with simply:

Δx = (80)(.968)

Δx = 77.46 feet
