For what x-values is the function positive? Select all that apply.
A-5 B. 0 C. 3 D. 3.5

Answer:

Yes

Step-by-step explanation:

Yes, 80 can be written in the form a / b where a and b are integers. In this case, a = 80 and b = 1. Plus, 80 itself is an integer and all integers are rational numbers.

Steps to solve:

3^2 • 3^-8 • 3^0

~Apple exponent rule [ a^b * a^c = a^b+c ]

3^2-8+0

~Simplify

3^-6

~Use exponent rule [ a^-b = 1/a^b ]

1/3^6

~Simplify

1/729

Best of Luck!

Answer:

3^-6 which equals 1/3^6

Step-by-step explanation:

all you do is add the exponents.

3^0 is equal to 0 so that one doesn't matter, you just cross it out.

now you're left with 3^2x3^-8

so add 2+(-8) which is -6 so the answer is: 3^-6

since the exponent is negative, you put a 1 above the problem, making it a fraction: 1/3^-6

Answer:

x < - 3

Step-by-step explanation:

Given the interval (- ∞, - 3 )

The parenthesis on both ends indicates that x cannot equal the end values.

Thus

x < - 3 represents the interval

Answer:

A plane extends infinitely in two dimensions. It has no thickness. An example of a plane is a coordinate plane. A plane is named by three points in the plane that are not on the same line.

Step-by-step explanation:

[tex]\bf Step-by-step~explanation:[/tex]

Remember: In math, a plane is a flat, two-dimensional surface that stretches infinitely far in all directions.

An example of a plane would be the photo below.

The purple rectangle is one plane, and the brown one is another one. If there are points there, then they would be on both planes if the points lie exactly on the intersection between the two planes.

We label planes when they have a letter (K, M, etc.), or if there are three non - collinear points on one plane, we take those letters and make them into the plane's name. (ex: Plane AGE, QDE, etc.)

Answer:

C . y= 5x -18

Step-by-step explanation:

[tex](5,7) = (x_1 ,y_1) \\ (8,22)=(x_2,y_2)[/tex]

Plug in the values into the following equation

[tex] \frac{y - y _1}{x - x_1} = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

[tex] \frac{y - 7}{x - 5} = \frac{22 - 7}{8 - 5} \\ \frac{y - 7}{x - 5} = \frac{15}{3} [/tex]

Cross Multiply

[tex]3(y - 7) = 15(x - 15) \\ 3y - 21 = 15x - 75[/tex]

Collect like terms and simplify

[tex]3y = 15x - 75 + 21 \\ 3y = 15x - 54[/tex]

Divide through by 3

[tex] \frac{3y}{3} = \frac{15x}{ 3 } - \frac{54}{3} \\ y = 5x - 18[/tex]

Answer:

A and D.

Step-by-step explanation:

4 is an integer which is a whole number.

3.2 is a decimal, so it is not a whole number.

4/7 is a fraction that cannot be simplified.

8/4 is a fraction that can be simplified to give 2, a whole number.

Answer:

Option (2)

Step-by-step explanation:

From the picture attached,

m∠JKL = m∠JMK + m∠KML

Since, m∠KML + m∠HML = 180° [Linear pair of the angles]

m∠HML = 180° - m∠KML

              = 180° - 132°

              = 48°

Therefore, m∠JML = 41° + 48°

                               = 89°

Since measure of angle JML is less than 90°, by definition of an acute angle it will be an acute angle.

Option (2) will be the answer.

Answer:

The answer is acute bru

Step-by-step explanation:

Answer:

The measure of the three angles are;

The first angle is 62°

The second angle is 28°

The third angle is 90°

Step-by-step explanation:

The given information are;

The shape of the parking lot = Triangular

Let the angles of the triangle be given as follows

First angle = A

Second angle = B

Third angle = C

The given triangle interior angle dimensions are;

A = 6 + 2× B

C = A + B

However, we have;

A + B + C = 180° (Angle sum property for a triangle)

Therefore;

A + B + C = 180° gives;

C + C = 180° (Transitive property)

2·C = 180°

C = 180°/2 = 90°

C = 90°

However, C = A + B  therefore;

90° = A + B and, A = 6 + 2 × B, we get;

A + B = 90° (Symmetric property)

6 + 2× B + B = 90° (Substitution property)

6 + 3·B = 90°

3·B = 90° - 6° = 84°

B = 84°/3 = 28°

B = 28°

From, A = 6 + 2 × B, we have;

A = 6 + 2 × 28° = 62°

A = 62°

First angle = A = 62°

Second angle = B = 28°

Third angle = C = 90°

The measure of the three angles are;

First angle is 62°

Second angle is 28°

Third angle is 90°.

Answer:

The average velocity of the ball at the given time interval is -122.3 ft/s

Step-by-step explanation:

Given;

velocity of the ball, v = 34 ft/s

height of the ball, y = 34t - 26t²

initial time, t₀ = 3 seconds

final time, t = 3 + 0.01 = 3.01 seconds

At t = 3 s

y(3) = 34(3) - 26(3)² = -132

The average velocity of the ball in ft/s is given as;

[tex]V_{avg} = \frac{y(3.01)-y(3)}{3.01 -3}\\\\V_{avg} = \frac{34(3.01)-26(3.01)^2-y(3)}{3.01 -3}\\\\V_{avg} = \frac{-133.223-y(3)}{0.01}\\\\V_{avg} = \frac{-133.223-(-132)}{0.01}\\\\V_{avg} =\frac{-1.223}{0.01}\\\\V_{avg} = -122.3 \ ft/s[/tex]

Therefore, the average velocity of the ball at the given time interval is -122.3 ft/s

Answer:

Step-by-step explanation:

To write 3km: 500m in its lowest terms. we need to make sure the units are the same.

Converting 3km to metres:

Since 1km = 1000m

3km = (3*1000)m

3km = 3000m

The expression becomes 3000m:500m

3000m:500m = 3000/500

3000m:500m = 6*500/500*1

3000m:500m = 6/1

Hence 3km: 500m in its lowest term is 6:1
