Square root of 5u+2 = square root of 3u+14

alina1380 [7]

Sqrt(5u + 2) = sqrt(3u + 14)
Square both sides to clear the square root.
5u + 2 = 3u + 14
subtract 3u from both siides
2u + 2 = 14
subtract 2 from both sides
2u = 12
divide both sides by 2
u = 6
When you square a square root you MUST check the solution.
sqrt(5*6 + 2) = sqrt(3*6 + 14)
sqrt(32) = sqrt(32)

consider the following.find formula simplify answer .Find the domain for the formula and round answer to two decimal places if n

Elanso [62]

The sum of functions is given as:

$(f+g)(x)=f(x)+g(x)$

In this case we have:

$(f+g)(x)=5x+\sqrt[]{x-1}$

The domain of the functions is any number that makes the squared root a real number, then:

$\begin{gathered} x-1\ge0 \\ x\ge1 \end{gathered}$

Hence the domain of the functions is:

$\lbrack1,\infty)$

Kendra ordered a set of blue and brown pins. She received 100 pins, and 30% of them were blue. How many blue pins did Kendra rec

natka813 [3]

Answer:

30 blue pins

Step-by-step explanation:

30% is the same as 30 out of 100, so this can be written in this fraction: $\frac{30}{100}$

now, you should multiply this fraction by the total number of pins she ordered:

100 x $\frac{30}{100}$

to solve this, you can simplify by dividing 100 by 100, this equals 1

30 times 1 is 30

there are 30 blue pins

Jerry indicated that after tossing a penny 30 times, the relative frequency of heads was 0.47 (to the nearest hundredth). He ind

natali 33 [55]

Answer:

Incorrect.

Step-by-step explanation:

1 toss could not change the frequency by such a large margin 0.47 ---> 0.55.

The number of heads obtained in 30 tosses = 30 * 0.47 = 14.

So if the next toss came up heads the relative frequency of heads would be

15/31 = 0.48.
