Why is the domain of the square root parent function x ≥ 0 and the domain of the cube root parent function all real numbers?

Answer:

-5, -2/3, 3/4, 7

Step-by-step explanation:

The solutions are solutions of one of the following:

(3x^2 + 17x + 10) = 0, x - 7 = 0, 4x - 3 = 0

The latter two are straightforward: x = 7 or 3/4.

To factor the first, note it must be of the form (3x + __) (x + __)

Check the pairs (10, 1) (1, 10) (5, 2) and (2, 5) and we find:

(3x + 2) (x + 5) = 0

So, we also have solutions -5, -2/3

Answer:

0.373248

Step-by-step explanation:

P(A and B) = P(A) * P(B)

Let's say one person wearing a seat belt is event A, the second person wearing a seat belt is event B, and the third person wearing their seat belt is event C

P(A and B and C) = P((A and B) and C) = (P(A) * P(B)) *P(C) = P(A) * P(B) * P(C)

The probability of each is 0.72. Our answer is therefore 0.72 * 0.72 * 0.72, or 0.72³ = 0.373248

From the area of the parallelogram, it is found that 8 cans of stain will be needed to stain the deck.

The area of a parallelogram of base length l and height h is given by:

A = lh

In this problem, the dimensions are l = 27, h = 11.

Hence, the area, in square feet, is given by:

A = 27(11) = 297.

Each can cover 40 square feet. How many cans are needed for 297 square feet?

[tex]n = \frac{297}{40} = 7.425[/tex]

Rounding up, 8 cans of stain will be needed to stain the deck.

Answer:

more than 22

Step-by-step explanation:

last year average 21points per game

so they need at least 22 points per game to be better than last year average

to get 22 points per game average (for the first three game)

they need to score total = 22 × 3 games = 66 points

then, minus total score they need to goal

66 - 14 -30

= 22 point more to score

Answer:

Length = 13

Step-by-step explanation:

P = 2L + 2W

L = 4W + 1

P = 32

32 = 2(4W +1)  + 2W

32 = 8W + 2 + 2W

30 = 10W

W = 3

L = 4(3) + 1

L = 12 + 1

L = 13

Answer:

y = -4x + 5

Step-by-step explanation:

choose 2 easy-to-read points on the line:  (0, 5) and (2, -3)

Because we have chosen the point that intersects the y-axis (0, 5) we know that the y-intercept of the line is 5.

Using equation of a line in slope-intercept form: y = mx + b (where m is the slope and b is the y-intercept):

The slope of the line = change in y ÷ change in x = (-3 - 5) ÷ (2 - 0) = -4

Therefore, y = -4x + 5

Answer:

I think its A

Step-by-step explanation:

The approximate measure of angle A is 104.48 degrees. The correct option is D.

Given that:

a = 16 cm

b = 12 cm

c = 8 cm

To find the measure of angle A in the triangle, use the law of cosines.

The law of cosines states that for any triangle with sides a, b, and c, and the angle opposite side c, denoted as C:

c² = a² + b² - 2ab × cos(C)

In this case, we want to find angle A, which is opposite side a. So, the equation becomes:

a² = b² +c² - 2bc × cos(A)

Now, plug in the given values:

16² = 12² + 8² - 2 × 12 × 8 × cos(A)

256 = 144 + 64 - 192 × cos(A)

Now, isolate cos(A):

192 × cos(A) = 144 + 64 - 256

192 × cos(A) = -48

cos(A) = -48 / 192

cos(A) = -1/4

Now, to find the measure of angle A, take the inverse cosine (cos^-1) of -1/4:

[tex]A \approx cos^{-1(-1/4)}[/tex]

A ≈ 104.48 degrees.

So, the approximate measure of angle A is 104.48 degrees. The correct option is D.

Answer:

A manufacturing corporation make tires with a probability 0.77 of lasting over 3,000 miles.

Step-by-step explanation:

The probability of exactly seven out of the next eight tires lasting over 3,000 miles will be 0.32.

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli's trials are those trials which end up randomly either on success (with probability p) or on failures (with probability 1- p = q (say))

The probability that out of n trials, there'd be x successes is given by

[tex]\rm P(X =x) = \: ^nC_x \ p^x(1-p)^{n-x}[/tex]

A manufacturing corporation make tires with a probability 0.79 of lasting over 3,000 miles.

The probability of exactly seven out of the next eight tires lasting over 3,000 miles will be

P(x = 7) = ⁸C₇ (0.79)⁷  (1 – 0.79)⁽⁸⁻⁷⁾

Step-by-step explanation:

I tried to see many ways as possible

Step-by-step explanation:

10.

angle QUR must be 180-41 = 139°

the reason : all angles on one side of the line QS around a single point (like U) must be 180°, as this represents a half-circle.

11.

the angle RUQ is larger.

the angle TUS is 90°.

therefore, SUN is 90° too. as well as TUQ and QUN.

the angle TUR is then TUS + 41 = 90+41 = 131°

and we know from 10. that QUR (or RUQ) is 139°.

therefore, RUQ is larger.

12.

when 2 lines cross, then the diagonally opposing angles are identical.

therefore,

84 = 4x

x = 21

13.

the same principle as in 10. applies.

all angles in one side of a line around a single point must be 180°.

so,

KMH + 84 = 180

KMH = 96°

14.

EBD = 90°

therefore, also ABE = 90°.

and we can imagine that BE extends straight to the other side of B having a point G there.

and then ABG = DBG = 90° as well.

and because these 90° angles and the principle of 12., we have

ABF = CBD = 90-62 = 28°

therefore,

CBE = CBD + DBE = 28 + 90 = 118°.

15.

ABF = 28°

as we calculated that in 14 already.

16.

due to the principles of 14 and 10 we have

CBA = 180 - CBD = 180 - 28 = 152°.

17.

this is not relevant to any of the pictures before.

angle A = angle B + 4

complementary angles are together 90°.

so,

A + B = 90

now we use the identity of the first equation in this main equation :

(B + 4) + B = 90

2B + 4 = 90

2B = 86

B = 43°

=>

A = B + 4 = 43 + 4 = 47°

18.

again, this is not related to any of the pictures before.

supplementary angles are together 180°.

D = 5E

D + E = 180

5E + E = 180

6E = 180

E = 30°

=>

D = 5E = 5×30 = 150°
