What do you do with negative exponent?

a/b The decay can be modeled by this equation, (1 - r), the r being the rate of decay. So it would be 1-0.115. (0.115 is your answer for a) You have to convert the percent into a decimal by moving the deicmal place two places to the left. 0.885 is your answer for b.

c. For function notation, that just means write an equation. So you want your decay times your inital.  V(t)=15000(0.885)^x. We get the V(t) from the directions that they want us to put it in; it's basically y.

d. Since it's two years, plug in 2 for x. This shows the decay after two years

V(t)=15000(0.885)^2

e. As with d, plug in 10 for x. V(t)=15000(0.885)^t

Answer:

Not a function

Step-by-step explanation:

A relation is considered a function if and only if every input value has exactly one output value.

The relation given does not satisfy the condition of a function. The input value, height = 160 cm, is related to different output values (age).

Therefore, the relation is not a function.

Answer:

b = 5.5

Step-by-step explanation:

In a paralelogram

A = bh

Just plug in the numbers

they said A = 60

and the number 11 is the height

60 = 11b

Divide

b = 60/11

b = 5.454545454

Answer:

For the one in the picture, it is 121. A.

Step-by-step explanation:

This is because 45% of 220 is 99. But, the question is asking for how many coins are NOT, so you do 220 - 99 to get 121.

m=0

y=3

Answer:

y=3

Step-by-step explanation:

Something that I notice about this is that the 2 y coordinates are the same

This means that the line isn't increasing nor decreasing, it's constant

if we look at the y=mx+b

we have, so far,

y=0x+b

we just need be

we know that when x=4 y=3 so we have

3=(0)(4)+b

b=3

so the answer is just y=3

Answer:

[tex]P(x \ge 45000) = 0.77935[/tex]

Step-by-step explanation:

Given [Missing from the question]

Exhibit Teacher's Salary:

[tex]\bar x=50000[/tex]

[tex]s = 6500[/tex]

Required

Calculate [tex]P(x\ge 45000)[/tex]

First, we calculate the z score

[tex]z = \frac{x - \bar x}{s}[/tex]

[tex]z = \frac{45000 - 50000}{6500}[/tex]

[tex]z = \frac{-5000}{6500}[/tex]

[tex]z = -0.77[/tex]

[tex]P(x \ge 45000) = P(z \ge -0.77)[/tex]

[tex]P(x \ge 45000) = 1 - P(z \le -0.77)[/tex]

From the table:

[tex]P(z \le -0.77) = 0.22065[/tex]

So, we have:

[tex]P(x \ge 45000) = 1 - 0.22065[/tex]

[tex]P(x \ge 45000) = 0.77935[/tex]

Answer:

(0,0) or Infinitely many solutions.

Step-by-step explanation:

-−4x−4y=0

−4x−4y+4y=0+4y(Add 4y to both sides)

−4x=4y

−4x/-4= 4y/-4

(Divide both sides by -4)

x=−y

4x+4y=0

4(−y)+4y=0

0=0

Answer:

There is no picture... But here is a representation of the inequality on a graph

The graph 2x - 5y < 3 cut the x-axis at the point (3,0) and the y-axis at the point (0,-0.6).

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.

Given inequality is 2x - 5y <3. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

When the inequality 2x - 5y < 3 is plotted on the graph it covers the region which is less than the line 2x - 5y < 3. The graph cut the x-axis at the point (3,0) and the y-axis at the point (0,-0.6).

The graph of the given inequality is attached with the answer below.

Answer:

a) 20 sixth graders.

b) 6 sixth graders.

c) 2/9x sixth graders.

d) 189 students in the school.

Step-by-step explanation:

a) 2/9 of 90 = 2/9 * 90 = 20 students.

b) 2/9 of 27 = 2/9 * 27 = 6 students.

c) 2/9 of x = 2/9x

d) 42 = 2/9x so solve the equation: x = 189 students.

If we have 90 students in the school then we will have  20 sixth grade students.

a. From the details of the question, we have 2/9 of the students in the school in sixth grade. Hence;

Number of students in sixth grade = 2/9 × 90 = 20 sixth grade students

b. If the school has 27 students, number of sixth graders =  2/9 ×  27 = 6 sixth grade students

c. If we have x students in the school, the number of sixth graders =  2/9 × x = 2/9x students

d. If we have 42 students in sixth grade, the number of students in the school is;

2/9 × x = 42

x = 9/2 × 42 = 189 students

Answer:

1. 17.8 cm

2. 32.0 cm

3. 15.9 m

Step-by-step explanation:

1. Determination of the length of the arc.

Radius (r) = 6 cm

Angle at the centre (θ) = 170°

Pi (π) = 3.14

Length of arc (L) = ?

L = θ/360 × 2πr

L = 170/360 × 2 × 3.14 × 6

L = 17/36 × 37.68

L = 17.8 cm

2. Determination of the length of the arc.

Diameter (d) = 13 cm

Angle at the centre (θ) = 282°

Pi (π) = 3.14

Length of arc (L) = ?

Next, we shall determine the radius. This can be obtained as follow:

Diameter (d) = 13 cm

Radius (r) =?

r = d/2

r = 13/2

r = 6.5 cm

Finally, we shall determine the length of the arc. This can be obtained as follow:

Radius (r) = 6.5 cm

Angle at the centre (θ) = 282°

Pi (π) = 3.14

Length of arc (L) = ?

L = θ/360 × 2πr

L = 282/360 × 2 × 3.14 × 6.5

L = 282/360 × 40.82

L = 32.0 cm

3. Determination of the length of the arc.

Radius (r) = 11 m

Angle at the centre (θ) = 83°

Pi (π) = 3.14

Length of arc (L) = ?

L = θ/360 × 2πr

L = 83/360 × 2 × 3.14 × 11

L = 83/360 × 69.08

L = 15.9 m
