2 Points
What is the principal square root of 16?
A. 4
B. -2
C.-4
D. 2​

Answer: 8.94

Step-by-step explanation:

By common logic, you can say that l=8, w=4 and h=2.

The diagonal of the base can be found by using Pythagorean Theorem.

Pythagorean Theorem: a²+b²=c²

Since we know the a and b of the base, we can find c, the diagonal.

a and b is the l and w. We can use the equation to find c.

8²+4²=c²

64+16=c²

80=c²

c=√80

c≈8.94

The diagonal is approximately 8.94

Step-by-step explanation:

2/5

If Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability Kostya chooses a number less than 5.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that Kostya randomly chooses a number from 1 to 10.

We have to find the  probability he chooses a number less than 5

There are four numbers that are less than 5 .

The numbers less than 5 are 1, 2, 3, 4.

The probability that Kostya randomly chooses one of these numbers is 4/10,

Divide numerator and denominator by 2

We get 2/5

Hence, if Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability he chooses a number less than 5.

Step-by-step explanation:

Answer:

Step-by-step explanation:

a² + b² + c² = 39

ab + bc + ca = 21

(a + b + c)² = a² + b² +c² + 2[ab + bc +ca]

(a + b + c)² = 39 + 2*21

                 = 39 + 42

(a+ b + c)² = 81

a +b + c = √81 = √9*9

a + b + c = 9

Answer:

Each x value occurs only once

Step-by-step explanation:

In order for something to be classified as a function, it must pass the vertical line test, meaning a vertical line should never hit 2 points on the function, meaning each x value appears once. Y values can occur as many times, as long as each x value occurs once, it is a function. In this case, a y value appears 2 times, but each x value only does so once.

Answer:

x ≤5

Step-by-step explanation:

There is a closed circle at 5 so that means equals

The line goes to the left so that means less than

x ≤5

Answer:

C

Step-by-step explanation:

Since the circle is close, we can assume it has to be C or D. But if we want to find out, we think of x as let's say 4. 4 is less than 5, and numbers 5 or less is x, so the answer would be C. (hope it helps)

Answer:

1,444 square yards

Step-by-step explanation:

38x38=1,444

If this side length is 38 and the field is a square then the lengths would be 38 yards all the way around. Area=LxW

Answer:

A =1444 yd^2

Step-by-step explanation:

The area of a square is given by

A = s^2 where s is the side length

A = 38^2

A =1444 yd^2

Answer:

80 feet

Step-by-step explanation:

length of pool = 22    ,  width of pool = 18

feet required for fencing the pool = 2 (l +b)

= 2 ( 22+18)

=2*40

=80feet

Answer:

Step-by-step explanation:

The pool is a rectangle as length and breadth are different.

Since they are asking about fencing you need to find the perimeter.

Length=22feet

Breadth=18feet

Perimeter of a rectangle = 2(l+b)

= 2 × 22 + 2×18

=44+36

=80 feet

Step-by-step explanation:

The solution of the expression √14 × √10​ is 2√35. The correct option is D.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is √14 × √10​. The expression will be solved as,

E = √14 × √10​

E = 2 √( 7 x 5 )

E = 2√35

Therefore, the solution of the expression √14 × √10​ is 2√35. The correct option is D.

Step-by-step explanation:

Answer:

slope: -3

y-intercept: -5

equation: y = -3x - 5

Step-by-step explanation:

The formula for slope is:

(y2 - y1)/(x2 - x1)

Let's use these coordinates:

(-1, -2)

(0, -5)

x1 = -1

x2 = 0

y1 = -2

y2 = -5

Substitute into the formula:

(y2 - y1)/(x2 - x1)

(-5 + 2)/(0 + 1)

Solve:

(-5 + 2)/(0 + 1)

-3/1

= -3

slope = -3

The y-intercept is when the x coordinate is 0.

Looking at the table, we see the coordinate (0, -5).

The y-coordinate is -5.

This means that the y-intercept is -5

y-intercept = -5

Slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept

m = -3

b = -5

Substitute:

y = mx + b

y = -3x - 5

Answer:

I=V/R

Step-by-step explanation:

In this equation, we see that there are no numerical values so we can't exactly solve for the exact number. Because of this, all you do Is isolate the variable "I" by itself. To do this, divide R on both sides. This way, you isolate I and on the other side you get V/R that cannot be further simplified.

Answer:

I=V/R

Step-by-step explanation:

V=IR

Divide both sides by R to isolate I

V/R=I

All options could change a taxpayer's adjusted gross income when filing a federal income tax return.

Options A, B, C, and D are the correct answers.

Taxpayer-adjusted gross income (AGI) is a person's gross income (all income from various sources such as wages, self-employment, interest, dividends, and capital gains) minus certain deductions (such as contributions to a traditional IRA, alimony payments, and student loan interest).

We have,

- Medical and dental expenses are deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.

- Contributions to an IRA may be deductible, which would lower the taxpayer's adjusted gross income.

- Casualty and theft losses may be deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.

- Charitable contributions made are deductible if the taxpayer itemizes deductions, which would lower the taxpayer's adjusted gross income.

Thus,

All of the above could change a taxpayer's adjusted gross income when filing a federal income tax return.

Step-by-step explanation:

Answer: 2/3x

Step-by-step explanation:

First, you need to simplify your original line to point slope formula. Dividing the whole thing by 2 to get y by itself leaves you with

y = 3/2x - 1/2

Any perpendicular line has the opposite slope to the line it is perpendicular to, so you flip the slope to get 2/3x
