Answer:

3.9

√15=3.87298334... so rounded to the tenth is 3.9

Answer:

732

Step-by-step explanation:

Answer:

[tex] - \frac{5}{6} - \frac{2}{3} e = 24 \\ - 1.2 - 1.5e = 24 \\ - 1.5e = 24 + 1.2 \\ - 1.5e = 25.2 \\ e = - \frac{25.2}{1.5} \\ e = - 16.8 [/tex]

Answer: 6.4

Step-by-step explanation:

you take help of ratio in this case.

8/x = 2.5/2

or, (2.5).(x) = (8).(2)

or, x = 16/2.5

so, x = 6.4

Answer:

take the square of 1.5then subtract the square of 1.2 to get the square of the Missing side then get it's square root

Answer:

the domain is (x ≥ -1 ) if you need it in interval notation it is (-1, infinity )

(Warning: This may be wrong)

Answer:

The answer is t = 17

Step-by-step explanation:

Sum of angles on a straight line = 180⁰

(2t -7) + 90 + 49= 180

(2t -7) +139 = 180⁰

2t -7) = 180 - 139

2t - 7 = 41

2t = 41 - 7

2t = 34

Divide both sides by 2

t = 17

Answer:

n = 3.16 units; p = 5 units

Step-by-step explanation:

to find the length of the lines you need to use the pythagorean  theorem or a^2 + b^2 = c^2

in this case a is x, b is y, and c is the length

so for n it is:

1^2 + 3^2 = c^2 -->

1 + 9 = c^2 -->

10 = c^2

c = 3.16227766 or about 3.16 (this is n's length)

for p it is:

3^2 + 4^2 = c^2 -->

9 + 16 = c^2 -->

25 = c^2 -->

c = 5 (this is p's length)

the answer is 40

in

X 1 (+1) 2 (+1) 3 (+1) 4 (+1) 5

Y 4 (+9) 13 (+9) 22 (+9) 31 (+9) 40

Answer:

the missing value is 40 .

Step-by-step explanation:

if observed clearly the difference between every number is 9.

so 31+9 = 40 is the correct answer.

Answer:

14

Step-by-step explanation:

Convert [tex]\frac{7}{2}[/tex] to a fraction with a common denominator

[tex]\frac{7}{2} (\frac{2}{2} )=\frac{14}{4}[/tex]

You now divide the fractions to find the amount of correct measurements needed.

[tex]\frac{\frac{14}{4} }{\frac{1}{4} }[/tex] For dividing by a fraction it is the same a multiplying by its reciprocal.

This becomes [tex]\frac{14}{4} (\frac{4}{1} )=\frac{14}{4} (4)=14[/tex]

You will need 14 correct measurements.

Answer:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

What is a polynomial?

  - In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables

What is a rational function?

- In mathematics, a rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials.

Are all polynomials rational functions?

.A function that cannot be written in the form of a polynomial, so no they are not all functions.
