Hi there!

[tex]\large\boxed{-40 + 20i}[/tex]

Recall the rules for the imaginary number "i":

i = √-1          i² = -1

Given:

(5i) (5i) + (5i) (4 + 3i)

Multiply:

(25i²) + 20i + 15i²

Simplify using the rule above:

25(-1) + 20i + 15(-1)

-25 + 20i - 15

-40 + 20i

a = -40

b = 20

Answers

Answer:

option A is correct. this graph is a linear function

Step-by-step explanation:

Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept

Answer:

It is not a function at all because it does not have necessary properties of a function, it is just a graph

A car is traveling at a constant speed of 55 miles per hour. Using m for miles and t for time, write 2 equations to represent this situation. One equation to solve for miles and the other equation to solve for hours.

Answers

Answer:

m = 55t

t = m/55

Step-by-step explanation:

According to the formula for calculating speed expressed as;

Speed = distance/time

Given;

Distance = 55mph

required:

distance as a function of t

time as a function of distance m

If distance is m and time is t

From the formula;

55 = m/t

m = 55t

Hence the equation to solve for miles m is m = 55t

To get t, we will cross multiply from 55 = m/t;

55t = m

Divide both sides by 55

55t/55 = m/55

t = m/55

Hence the equation to solve for time in hours is t = m/55

PLZ HELP I WILL MARK BRAINLIEST - What is the volume of a cone (in cubic inches) with a radius of 6 inches and a height of 3 inches?

Use 3.14 for π. Round your answer to the nearest hundredth.

37.68 cubic inches
56.52 cubic inches
100.48 cubic inches
113.04 cubic inches

Answers

Answer:

D: 113.04

Step-by-step explanation:

Volume cone formula: V=πr^2h/3

V = π(6)^2 3/3

V = 113.1

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Answer:

113.04 cubic inches

Step-by-step explanation:

First lets identify the equation to find the volume of a cone.

V= [tex]\pi[/tex] r^2 h/3

Next we'll plug in height and radius

h = 3

r = 6

V = [tex]\pi[/tex] 6^2 * 3/3

V = [tex]\pi[/tex] 36 * 3/3

V = [tex]\pi[/tex] 36 * 1

V = [tex]\pi[/tex] 36

V = 36[tex]\pi[/tex]

Now we'll use 3.14 for [tex]\pi[/tex] and times it by the 36

V = 36[tex]\pi[/tex]

V = 113.04

V= 113.04 cubic inches

Choose all the measurements that are equivalent to 45 meters. (1 pt.) RP.1.3 d a.0.045 kilometers b.0.45 kilometers c.450 centimeters d.4,500 centimeters e.45,000 millimeters answer fast please

Answers

Answer:

a.0.045km

d.4500cm

e.45000mm

Step-by-step explanation:

45meters is equivalent to 0.045km,4500cm,45000mm

Therefore the right answers are

a.0.045km

d.4500cm

e.45000mm

To determine which measurements are equivalent to 45 meters, we need to convert the given options to meters and compare them to 45 meters is 0.045 kilometers Therefore the correct option is A,B,D,E.

a. 0.045 kilometers: To convert kilometers to meters, we multiply by 1000. So, 0.045 kilometers is equal to 0.045 x 1000 = 45 meters. b. 0.45 kilometers: Similarly, 0.45 kilometers is equal to 0.45 x 1000 = 450 meters. c. 450 centimeters: To convert centimeters to meters, we divide by 100. So, 450 centimeters is equal to 450 / 100 = 4.5 meters.

d. 4,500 centimeters: Again, 4,500 centimeters is equal to 4,500 / 100 = 45 meters. e. 45,000 millimeters: To converted millimeters to meters, we divide by 1000. So, 45,000 millimeters is equal to 45,000 / 1000 = 45 meters.

Therefore, the measurements that are equivalent to 45 meters are a. 0.045 kilometers, b. 0.45 kilometers, d. 4,500 centimeters, and e. 45,000 millimeters. These measurements all represent the same length as 45 meters.

Hence the correct option is A,B,D,E.

the metal bar/random line is almost the same size as the other two sides of the triangle. if one side is 32ft, then the opposite side is 32ft also. the bottom is 100ft, so we could eliminate C. because it couldnt be that number. now the bottom triangle, one side is 40ft so the other side has to be 40ft as well. its asking about the metal bar.

its either:

A. 53.2ft     or

B. 44.4

because the line is almost the same size as 32ft. its almost a equallateral triangle. i would go with A. though because if you imagine the line at the bottom of the line (100ft.) the line would go over half of it (and 53.2 is over half of 100) so i would say

A.53.2

Daniel can spend no more than $40 at the fair. If admission into the fair is $10 and the rides cost $1.50 each, which inequality represents the greatest number of rides Daniel can go on?


A. 10r + 1.50 ≥ 40
B. 1.50r + 10 ≤ 40
C. 1.50r + 10 <40
D 10r+1.50<40

Explain your reasoning and solve the inequality :

Answers

Answer:

B

Step-by-step explanation:

The sum spent has to be either equal to or less than 40. So r many rides, each of them being 1.50, plus 10 dollars has to equal to less or equal to 40 dollars.

Answer:

The answer is B

The greatest number of rides Daniel can go on is 20.

Step-by-step explanation:

Total: The same or less than 40

Fair Admission: 10

ride: 1.50x

40 ≤ 10 + 1.5r

To solve:

40 ≤ 10 + 1.5r

40 - 10 ≤ 10 + 1.5r - 10

30 ≤ 1.5r

30 ÷ 1.5 ≤ 1.5r ÷ 1.5

20 ≤ r

The greatest number of rides Daniel can go on is 20.
