Answer:

[tex]-3u + 5g =-58i -25j[/tex]

Step-by-step explanation:

Given

[tex]u = 6i - 10j[/tex]

[tex]g=-8i - 11j[/tex]

Required

[tex]-3u + 5g[/tex]

We have:

[tex]-3u + 5g[/tex]

This gives:

[tex]-3u + 5g = -3(6i - 10j) + 5(-8i - 11j)[/tex]

Open bracket

[tex]-3u + 5g = -18i + 30j - 40i - 55j[/tex]

Collect like terms

[tex]-3u + 5g = -18i - 40i+ 30j - 55j[/tex]

[tex]-3u + 5g =-58i -25j[/tex]

Answer:

x=  12.528

*rounded is 12.53 or 12.5

Step-by-step explanation:

7.3 ^2 + x^2 = 14.5^2

53.29 + x^2 = 210.25

-53.29            -53.29

x^2= 156.96

x= 12.528

Answer:

D. 0.884

Step-by-step explanation:

I calculated it logically

The value of the amplitude is 0.884, so the correct option is d.

The amplitude is the coefficient that multiplies the sine function.

In this case, the function is:

y = 0.884*sin(0.245*x - 1.093) + 0.400

Comparing this with the general sine equation, you can see that the amplitude is equal to 0.884, so the correct option is d.

Answer:

3

Step-by-step explanation:

Evaluate the limit n - > ∞ 12n^3 - 2n^2 + 9 / 4n^3

Divide the expression by the highest power of n to have

limit n - > ∞ 12n³/n³ - 2n²/n³ + 9/n³ / 4n³/n³

= limit n -  > ∞12 - 2/n + 9/n³ / 4

Substitute the value of n

= 12 - 2/∞ + 9/∞³ / 4

Since a/∞ = 0

The expression becomes;

= 12 - 0+ 0/4

= 12/4

= 3

Hence the required limit is 3

Answer:

The 95% confidence interval to determine the true proportion of all patrons who would be interested in attending the showing is (0.2121, 0.4671).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

Of the 53 patrons, 18 said that they would come to see the film.

This means that [tex]n = 53, \pi = \frac{18}{53} = 0.3396[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3396 - 1.96\sqrt{\frac{0.3396*0.6604}{53}} = 0.2121[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3396 + 1.96\sqrt{\frac{0.3396*0.6604}{53}} = 0.4671[/tex]

The 95% confidence interval to determine the true proportion of all patrons who would be interested in attending the showing is (0.2121, 0.4671).

Answer:

2(1 - x)

Step-by-step explanation:

Twice the difference of 1 and a number

a number = x

The difference of 1 and a number is expressed as :

1 - x

Twice this difference, means the difference of (1-x) multiplied by 2

2 * (1 - x) = 2(1 - x)

Answer:

x= 15/9 fl oz

Step-by-step explanation:

 write the such that chemicals are on one side of : and water on the other

   chemical : water

                 1 : 9

x chemical : 15 of water

now we know that

x/1 = 15/9  cross multiply to find x

x= 1*15/9 = 15/9  ≈ 1.67 fl oz

Answer:

Since Tina wants to buy grass seed to cover her whole lawn, except for the pool, and the pool is 7/12 m by 3/14 m, to find the area the grass seed needs to cover the following calculation must be performed:

It is impossible to determine the area that the grass seed needs to cover, because we do not have the data of the total size of the lawn. Now, you can determine the size of the surface that should not be covered, which is the one that the pool occupies, namely:

7/12 x 3/14 = X

0.583333 x 0.2142 = X

0.1249 = X

Therefore, the grass seed should not cover about 0.1249 square meters.

Answer:

Jocelyn's plane travelled 3650 miles.

Step-by-step explanation:

mph stands for miles per hour.

Let's set up an equation.

total miles = speed(hours)

Jocelyn's plane travelled 500 mph for 7.3 hours.

total miles = 500(7.3)

Multiply.

total miles = 3650

Jocelyn's plane travelled 3650 miles.

Answer:

19nhours

Step-by-step explanation:

If we are in the real numbers, we don't have solutions:

[tex]x^2 +49 = 0 \implies x^2 = -49 \implies x \not\in\mathbb{R}[/tex]

If we go beyond:

[tex]x^2 +49 = 0 \implies x^2 = -49 \implies x = \pm\sqrt{-7^2} \implies x = \pm7i[/tex]

Answer:

m<HJK = 40°

Step-by-step explanation:

Given:

m<HJK = 3x - 2

m<KJL = 50°

Required:

m<HJK

Solution:

m<HJK + m<KJL = 90° (complementary angle)

Substitute

3x - 2 + 50 = 90

Add like terms

3x + 48 = 90

3x + 48 - 48 = 90 - 48

3x = 42

3x/3 = 42/3

x = 14

✅m<HJK = 3x - 2

Plug in the value of x

m<HJK = 3(14) - 2 = 42 - 2

m<HJK = 40°

Answer:

15x + 190 >= 400

* >= means greater than or equal to *

at least 14 friends

Step-by-step explanation:

without the inequality it'd be 15x + 190 = 400

but since you want it to be at least 400 you change the = to the greater than or equal to sign

15x + 190 = 400 * subtract 190 from both sides*

15x = 210 *divide both sides by 15*

x = 14

Answer:

x=9

Step-by-step explanation:

This equation, in my use, is more of a guess-and-check. I noticed 15 divides nicely into 135 and then punched that into my calculator. 135/15 = 9. And when you add 9 and 6 together, it makes 15. Therefore, x must equal 9.
