The bill for a person who uses 300 kWh in a month is $40

The piecewise function of how the power company calculates the bill is given as:

b(x) = 0.150x, x < 200

b(x) = 0.10(x - 200) + 30, x >= 200

For a person who uses 300 kWh in a month, the value of x is 300.

i.e. x = 300

By comparing the domain of the piecewise function, we make use of the following function

b(x) = 0.10(x - 200) + 30, x >= 200

Remove the domain

b(x) = 0.10(x - 200) + 30

Substitute the known values in the above equation

b(300) = 0.10(300 - 200) + 30

Evaluate the difference

b(300) = 0.10(100) + 30

Evaluate the product

b(300) = 10 + 30

Evaluate the sum

b(300) = 40

Hence, the bill for a person who uses 300 kWh in a month is $40

Answer:

a) 36

b) 11:5

Step-by-step explanation;

a) let the number of cold stone cones be x

Since the initial ratio is 11:9

we have the ratio of the ice creams as;

11:9 = 44:x

11/9 = 44/x

11 * x = 9 * 44

x = (9 * 44)/11

x = 9 * 4 = 36

b) Now, from 36, we have a number of cold stones as 20

So the ratio now will be;

44:20

and that would be;

11:5

Answer: [tex]\dfrac{x^2}{9}+\dfrac{y^2}{9}=1[/tex]

Step-by-step explanation:

Given

[tex]x=3\sin 2\phi\\y=3\cos 2\phi[/tex]

square and add [tex]x\ \text{and}\ y[/tex] terms i.e.

[tex]\Rightarrow x^2+y^2=[3\sin 2\phi]^2+[3\cos 2\phi]^2\\\Rightarrow x^2+y^2=9\sin ^22\phi+9\cos ^2 2\phi\\\Rightarrow x^2+y^2=9[\sin^2 2\phi +\cos^2 2\phi]\\[/tex]

Using identity [tex]\sin ^2\theta +\cos ^2 \theta =1[/tex]

[tex]\Rightarrow x^2+y^2=9\\\\\Rightarrow \dfrac{x^2}{9}+\dfrac{y^2}{9}=1[/tex]

Answer:

EWWWWWWWWWWWWW UR BI???!!

Step-by-step explanation:

Answer:

Calculating for a FULL SPHERE

sphere radius = cube root (.75 * sphere volume / PI)

sphere radius = cube root (.75 * 91,358 / 3.14159265)

sphere radius = 27.9395447176 inches

That's for a FULL SPHERE.  

For a HEMISPHERE we divide by two:

13.9697723588

To the nearest tenth of an inch it is

14.0 inches.

Answer:

Step-by-step explanation:

There are four points here.  We look at the x-values and identify {2, 1, -2, 1].  This can be reduced to {-2, 1, 2}

Unfortunately, the input '1' shows up twice and thus the relation cannot be a function; we cannot have two different y-values for the same x-value (1).

Answer:

Diameter = 2.68cm

Step-by-step explanation:

Circumference of a circle = 2πr

Circumference of a circle = 8.44cm

π = 3.14

r = ?

Circumference of a circle = 2πr

8.44 = 2 * 3.14 * r

8.44 = 6.28r

r = 8.44/6.28

r = 1.3439490445859

Approximately

r = 1.34

Diameter = 2r

Diameter = 2 * 1.34

Diameter = 2.68cm

Answer:

-41.11°C to -5.56°C

Step-by-step explanation:

Given the formula for converting Celsius temperatures to Fahrenheit temperatures expressed as;

F = 9/5C + 32

If F = -42∘F

-42 = 9/5C + 32

9/5C = -42-32

9/5C = -74

9C = -74*5

9C = -370

C = -41.11°C

For F =22°F;

22 = 9/5C + 32

9/5C = 22-32

9/5C = -10

9C = 5*-10

9C = -50

C = -5.56°C

Hence the corresponding Celsius range would be -41.11°C to -5.56°C

Answer:

Options (1) and (3)

Step-by-step explanation:

Exterior angles of a triangle is equal to the sum of two remote interior angles of the triangle.

In triangle JMK,

∠JMF is the exterior angle and angles ∠KJM and ∠JKM are the remote interior angles.

m∠JMF = m∠KJM + ∠JKM

Therefore, Options (1) and (3) are the correct options.
