Three students made videos for their art project. The table shows the length of each video. How much longer is video 1 than video 3?

Answer:

If it wants you simplify the answer 6x + 21

Step-by-step explanation:

4x times 2x = 8x. Then 4x times 3 = 12x

Then 8x + 12x = 20x

-7 times 2x = -14x. Then -7 times -3 = 21

20x - 14x = 6x + 21

Answer:

12x+2y=-3

Step-by-step explanation:

y=-6x-3/2

-6x-y=3/2

2(-6x-y)=2(3/2)

-12x-2y=3

12x+2y=-3

Answer:

If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos(θ) to get the side adjacent to the angle. If you have the non-hypotenuse side adjacent to the angle, divide it by cos(θ) to get the length of the hypotenuse.

Step-by-step explanation:

[tex]\\ \rm\Rrightarrow cos40=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\\ \rm\Rrightarrow cos40=\dfrac{a}{10}[/tex]

[tex]\\ \rm\Rrightarrow 0.766=a/10[/tex]

[tex]\\ \rm\Rrightarrow a=0.766(10)[/tex]

[tex]\\ \rm\Rrightarrow a=76.6[/tex]

Answer:

7.66 (dp)

Step-by-step explanation:

Use the cosine trig ratio:

[tex]\mathsf{\cos(\theta)=\dfrac{A}{H}}[/tex]

where:

Given:

Substituting the given values into the equation:

[tex]\implies \mathsf{\cos(40)=\dfrac{a}{10}}[/tex]

[tex]\implies \mathsf{a=10\cos(40)}[/tex]

Answer:

1/4th of a second, or .25 seconds

Step-by-step explanation:

graphed it.

The grasshopper is 1 foot off the ground after 0.25 seconds.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

The given function is,

f(t) = -16t² + 8t

This represents the height y (in feet) of a grasshopper jumping straight up from the ground t seconds after the start of the jump.

We have to calculate the time t when f(t) = 1 foot.

-16t² + 8t = 1

-16t² + 8t - 1 = 0

This is a quadratic equation.

Solve using quadratic formula.

Discriminant = [tex]\sqrt{8^2-(4*-16*-1)}[/tex] = 0

t = (-8 ± 0) / (2 × -16) = -8/-32 = 0.25

Hence the time is 0.25 seconds when the grasshopper is at 1 foot.

Hence the grasshopper will be at 1 foot from the ground in 0.25 seconds.

Answer:

130.68 mm²

Step-by-step explanation:

given 2 similar figures with ratio of sides = a : b , then

ratio of areas = a² : b²

here ratio of sides = 5 : 11 , then

ratio of areas = 5² : 11² = 25 : 121

let x be the area of Δ YPR , then by proportion

[tex]\frac{25}{27}[/tex] = [tex]\frac{121}{x}[/tex] ( cross- multiply )

25x = 3267 ( divide both sides by 25 )

x = 130.68

area of Δ YPR ≈ 130.68 mm²

Answer:

270

Step-by-step explanation:

To solve this, we use the unitary method.

Distance flown in one sec =  [tex]\frac{180}{20}[/tex] = 9

Thus, distance flow in 30 secs = 9 × 30 = 270

Using the z-distribution, as we have the standard deviation for the population, it is found that the correct decision is given by:

Reject the null hypothesis. There is enough evidence to oppose the company's claim.

At the null hypothesis, it is tested if the mean is of 2.7 years, that is:

[tex]H_0: \mu = 2.7[/tex]

At the alternative hypothesis, it is tested if the mean is different of 2.7 years, hence:

[tex]H_1: \mu \neq 2.7[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

The parameters are:

In this problem, the values of the parameters are given by:

[tex]\overline{x} = 3.1, \mu = 2.7, \sigma = 0.85, n = 25[/tex]

Hence, the value of the test statistic is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{3.1 - 2.7}{\frac{0.85}{\sqrt{25}}}[/tex]

[tex]z = 2.35[/tex]

Considering a two-tailed test, as we are testing if the mean is different of a value, with a significance level of 0.05, the critical value is of [tex]|z^{\ast}| = 1.96[/tex].

Since the absolute value of the test statistic is greater than the critical value, the correct decision is:

Reject the null hypothesis. There is enough evidence to oppose the company's claim.

Answer:

Reject the null hypothesis. There is enough evidence to oppose the company's claim.

Step-by-step explanation:

The test statistic needs to fall within the rejection regions that are above and below the critical z-score associated with a 5% level of significance in order to reject the null hypothesis. Otherwise, we will fail to reject the null hypothesis.

Answer:

m = -1/2, y-intercept = -3, x-intercept = -6,0

Step-by-step explanation:

M is the gradient (or slope) and is always in front of the x coefficient. -1/2 in this case.

To find the y-intercept, we have to know that it is at the point where the graph passes through the y-axis. At this point x = 0. So just substitute 0 for x and solve for y to give -3.

To find the x-intercept, do the opposite. When the graph passes through the x-axis, y = 0. So when y = 0, x = -6

It is choice (D)

Let's set that unknown number to x.

The first step is the difference of 3 times a number and 15 --> 3x - 15

That is no less than the square of the number  '[tex]\geq[/tex] [tex]x^{2}[/tex]'

Now combine them [tex]3x - 15 \geq x^2[/tex]
