Answer:

320 cubic cm

Step-by-step explanation:

To answer a prism volume question, also see it as a shape (in this case a triangle) that is very thick.

First step is to calculate the area of the shape.  We all know the formula to calculate the area of a triangle: (b x h)/2.  And we those two measures.  The height of the triangle is b (8 cm), the base of the triangle is a (10 cm).

A = (b * h)/2 = (10 * 8) / 2 = 80 / 2 = 40 sq cm

Then we multiply the base area of the prism by its height to get the total volume. In this case, the height is also known, h = 8 cm.

V = b * h = 40 * 8 = 320 cubic cm

Answer:

320

Step-by-step explanation:

The volume of a prism is the height times the area of the base.

V = hA

The base is a triangle.  The volume of a triangle is half the base times height.

V = h (½ ab)

Given a = 10, b = 8, and h = 8:

V = ½ (8) (10) (8)

V = 320

Answer:

B

Step-by-step explanation:

An equation that represents the graph of g(x) include the following: B. [tex]g(x)=\sqrt[3]{x+2}[/tex].

In Mathematics, a translation is a type of transformation that shifts every point of a geometric object in the same direction on the cartesian coordinate, and for the same distance.

Based on the information provided in the diagram, we have the following:

(x, y)       →    (x + h, y + k)

(0, 0)     →    (-2, 0).

-2 = x + h

-2 = 0 + h

h = 0 - 2

h = -2 (2 units left)

0 = y + k

0 = 0 + k

k = 0.

In conclusion, a horizontal translation of 2 units to the left would map the parent cubic function f(x) to the transformed cubic function g(x);

g(x) = f(x + 2)

[tex]g(x)=\sqrt[3]{x+2}[/tex]

Answer:

[tex]\boxed{\text{48 ft}}[/tex]

Step-by-step explanation:

The angle of depression from the camera at D and the angle of elevation from the target cars are congruent.

1. Distance of car A from tower

Consider ∆ACD

tan25 = 50/AC

AC  = 50/tan25 = 50/0.4663 = 107.2 ft

2. Distance of car B from tower

Consider ∆BCD

tan40 = 50/BC

AC  = 50/tan40 = 50/0.8391 = 59.6 ft

3. Distance from cars A and B

AB = AC – BC = 107.2 – 59.6 = 48 ft

The distance between the two cars is [tex]\boxed{\textbf{48 ft}}[/tex].

Answer:

2(x + 4)(x − 3)

Step-by-step explanation:

Hope it helped you

Answer:

2(x + 4)(x - 3)

Step-by-step explanation:

Given

2x² + 2x - 24 ← factor out 2 from each term

= 2(x² + x - 12)

To factor the quadratic

Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (+ 1)

The factors are + 4 and - 3, since

4 × - 3 = - 12 and 4 - 3 = + 1, thus

x² + x - 12 = (x + 4)(x - 3) and

2x² + 2x - 24 = 2(x + 4)(x - 3)

Answer:

3  2/3 miles

Step-by-step explanation:

distance = rate times time.

Here,

distance = (5.5 mph)(2/3 hr) = 3  2/3 miles

The sailboat can travel 3 2/3 miles in 2/3 hours by multiplying the speed (5 1/2 miles per hour) by the time (2/3 hours) to get the distance.

To determine how far a sailboat can sail in 2/3 hours when it can sail 5 1/2 miles in one hour, we need to perform a multiplication of the speed by the time. The speed of the sailboat is 5 1/2 miles per hour (which is the same as 11/2 miles per hour in improper fraction form), and the time is 2/3 hours.

Here are the steps to calculate the distance:

Convert 5 1/2 miles to an improper fraction: 5 1/2 = (5 times 2 + 1)/2 = 11/2.

Multiply the speed by the time: (11/2) times (2/3) = (11 times 2)/(2 times 3) = 22/6.

Simplify the fraction: 22/6 = 11/3 = 3 2/3 miles.

Therefore, the sailboat can travel 3 2/3 miles in 2/3 hours.

Answer:

5) 140.8m^2   6) 360in^2

Step-by-step explanation:

5.

6.4 x 6.4 = 40.96

(7.8 x 6.4) ÷ 2 = 24.96

24.96 x 4 = 99.84

99.84 + 40.96 = 140.8m^2

6.

12 x 10 = 120in

13 x 10 = 130in

5 x 10 = 50in

(12 x 5) ÷ 2 = 30in

30 x 2 = 60in

60 + 50 + 130 + 120 = 360in^2

The 35th term is -8

EXPLANATION

The nth term of an arithmetic sequence is given by

[tex]a_n = a_1 + d( n - 1)[/tex]

We have the 17th term to be;

[tex]a_{17}=47[/tex]

and the common difference is d=-3

We substitute to get:

[tex]47= a_1 + - 3(1 7- 1)[/tex]

[tex]47= a_1 + 16( - 3)[/tex]

[tex]47= a_1 - 48[/tex]

[tex]a_1 = 48 + 47 = 95[/tex]

We can now find the 35th term:

[tex]a_{35}=a_{1} + 34d[/tex]

[tex]a_{35}=95 + 34( - 3) = - 8[/tex]

Answer:

(a) [tex]x ^ 2 + y ^ 2 = 6 ^ 2[/tex]

(b) [tex](x-1) ^ 2 + y ^ 2 = 1[/tex]

Step-by-step explanation:

Remember that to convert from polar to rectangular coordinates you must use the relationship:

[tex]x = rcos(\theta)[/tex]

[tex]y = rsin(\theta)[/tex]

[tex]x ^ 2 + y ^ 2 = r ^ 2[/tex]

In this case we have the following equations in polar coordinates.

(a) [tex]r = 6[/tex].

Note that in this equation the radius is constant, it does not  depend on [tex]\theta[/tex].

As [tex]r ^ 2 = x ^ 2 + y ^ 2[/tex]

Then we replace the value of the radius in the equation and we have to::

[tex]x ^ 2 + y ^ 2 = 6 ^ 2[/tex]

Then [tex]r = 6[/tex] in rectangular coordinates is a circle centered on the point (0,0) and with a constant radius [tex]r = 6[/tex].

(b) [tex]r = 2cos(\theta)[/tex]

The radius is not constant, the radius depends on [tex]\theta[/tex].

To convert this equation to rectangular coordinates we write

[tex]r = 2cos(\theta)[/tex]     Multiply both sides of the equality by r.

[tex]r ^ 2 = 2 *rcos(\theta)[/tex]    remember that [tex]x = rcos(\theta)[/tex], then:

[tex]r ^ 2 = 2x[/tex]        remember that [tex]x ^ 2 + y ^ 2 = r ^ 2[/tex], then:

[tex]x ^ 2 + y ^ 2 = 2x[/tex]         Simplify the expression.

[tex]x ^ 2 -2x + y ^ 2 = 0[/tex]     Complete the square.

[tex]x ^ 2 -2x + 1 + y ^ 2 = 1[/tex]

[tex](x-1) ^ 2 + y ^ 2 = 1[/tex]  It is a circle centered on the point (1, 0) and with radio [tex]r=1[/tex]

Answer: 228

[tex]\frac {60 \ s} {1 \ m} * 3 \ m = 180 \ s[/tex]

Answer:

(x + 12)(x + 2)

Step-by-step explanation:

In order to factorize, we first have to break the term in the middle into two terms which add up to 14 and and multiply to 24.

For this, let's take a look at the factor pairs of 24. We have (1, 24), (2,12), (3, 8), (4, 6).

note that the 2nd pair works. 2 + 12 = 14, 2*12 = 24.

And now we rewrite the expression.

x^2 + 14x + 24

= x^2 + 12x + 2x + 24

Take out common factors as below

= x(x + 12) + 2(x + 12)

Note that (x+12) is a common factor in the 2 added expressions. So we take it out.

= (x+12)(x+2)

Answer:

Step-by-step explanation:

The probability that the percent of 18 to 34-year-olds who check social media before getting out of bed in the morning is, at most, 32 is 0.7881 = 78.81%

When the distribution is normal, we use the z-score formula.

In a set with mean  [tex]\mu[/tex]and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z=\frac{X-\mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean.

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score.

This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.

Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

[tex]\mu=28,\sigma=5[/tex]

Find the probability that the percent of 18 to 34-year-olds who check social media before getting out of bed in the morning is, at most, 32.

This is the p-value of Z when X = 32. So

[tex]Z=\frac{X-\mu}{\sigma}[/tex]

[tex]Z=\frac{32-28}{5}[/tex]

[tex]Z=0.8[/tex]

Z=0.8 has a p-value of 0.7881

0.7881 = 78.81% probability that the percent of 18 to 34-year-olds who check social media before getting out of bed in the morning is, at most, 32.
