A) 10
B) 12
C) 14
D) 16​

Answers

Answer:

16

Step-by-step explanation:

The correct answer is option D which is the coordinate will be 16.

What is the midpoint?

The mid point of the line is defined as the center point of any line it means that the distance of this point is same from the one end and to the other end.

Given that:-

The midpoint between two points is (-16 12). of one endpoint is (-24 8) then the other is (-8,

The formula for calculating the midpoint of the line for the y coordinate will be:-

Ym= ( y1 + y2 ) / 2

12 = ( 8 + y2) / 2

24 = 8 + y2

y2 = 24 - 8

y2 = 16

Therefore the correct answer is option D which is the coordinate will be 16.

The rule is P(1+r%) power of time (T) so you're gonna apply the number to the rule

Step-by-step explanation:

P=7000

r=1.6%

T=12

7000 x (1+r%) power of T

(1+1.6%) power of 12 = 1.20983040

What are the two equations to set up to solve the equation |2x−3|=11

Answers

The two equations to set up to solve |2x−3|=11 are 2x − 3 = 11 and 2x − 3 = -11

Hence, option C)2x − 3 = 11 and 2x − 3 = -11 is the correct answer.

What are the two equations to set up to solve the equation |2x−3|=11?

Given the equation in the question;

| 2x − 3 | = 11

To solve the equation, we have to remove the absolute value term and this will create the a ± on the right side of the equation.

Note that; |x| = ±x

Hence;

| 2x − 3 | = 11

2x − 3 = ±11

The solution of the equation is the result of both the positive and negative portions of the of the solution.

2x − 3 = 11 and 2x − 3 = -11

Therefore, the two equations to set up to solve |2x−3|=11 are 2x − 3 = 11 and 2x − 3 = -11

Hence, option C)2x − 3 = 11 and 2x − 3 = -11 is the correct answer.

The cost of taxi ride is 5 dollars plus 50 cents per mile write an algebraic expression that models the cost of taxi ride m miles

Answers

f(m) = 5 + 0.5m is the algebraic expression that models the cost of taxi ride.

Here, we are given that the cost of taxi ride is 5 dollars plus 50 cents per mile.

This means that-

the fixed cost = $5

variable cost = 50 cents per mile = $0.5 per mile

Let the number of miles travelled be m

then the variable cost will be = $0.5m

The total cost is given as-

total cost = fixed cost + variable cost

total cost = 5 + 0.5m

⇒ f(m) = 5 + 0.5m

here, m = miles travelled

and f(m) = total cost of the taxi ride

Hence, f(m) = 5 + 0.5m is the algebraic expression that models the cost of taxi ride.

Which statement is correct?

The range of the graph is all real numbers greater than or equal to 0.
The domain of the graph is all real numbers greater than or equal to 0.
The range and domain of the graph are the same.
The domain of the graph is all real numbers.

Answers

Answer:

The domain of the graph is all real numbers.

Step-by-step explanation:

The equation that is set for this problem is y = |x+2| − 4. When finding the domain and range of this function, the domain and range is:

Domain: (−∞,∞), {x|x∈ℝ}   (The domain (x-values) is all real numbers

Range: [−4,∞), {y|y≥−4}  ⇒  (The range (y-values) need to be greater than or equal to −4)

So, according to this information and we look at the statements, out of the four, the correct option is “the domain of the graph is all real numbers”.

Answers

The number of calculations that a computer can perform in 10 seconds is 1050.

The exponential form of 1050 is 1.05 × 10³

Given,

The number of calculations that a computer can perform per second = 105

We have to find the number of calculations can it perform in 10 seconds.

That is,

Number calculations in 10 seconds = Number of calculations per second × 10

Number of calculations in 10 seconds = 105 × 10

Number of calculations in 10 seconds = 1050

That is, the number of calculations that a computer can perform in 10 seconds is 1050.

Answers

Answer:

Richard got a 90% score on his quiz! Therefore, he got 10% of the questions incorrect.

Step-by-step explanation:

The method I used to find this answer was simply taking the amount he had gotten, 36, and dividing it by the initial amount of questions- 40. From there, I got 0.9, which is the equivalent of 90%. 100% minus 90% is 10%, so he got 10% incorrect. Sorry for the mishap, I didn't pick up that it was meant to be the amount incorrect. :)
