Answer:

The percent of error in her measurement is 1.3%

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter

we have

D=5\ in

assume

\pi=3.14

substitute

C=(3.14)(5)=15.7\ in ----> This value represent the 100% (theoretical value)

Find the difference between the theoretical value and the measured value

15.7-15.5=0.2\ in

Find the percentage by proportion

15.7/100=0.2/x\\ x=100*0.2/15.7\\ x=1.3\%

Expand and combine like terms.<br> (3c^4-5c^6)^2
lora16 [44]

Answer:

9c^{8} -30c^{10} + 25c^{12}

Step-by-step explanation:

We can use formula (a-b)² = a² -2ab + b².

In our example a = 3c^4 and b = 5c^6

(3c^{4} - 5c^{6})^{2} = [3c^{4} ]^{2} - 2*3c^{4} *5c^{6} + [5c^{6}]^{2}=\\=9c^{8} -30c^{10} + 25c^{12}

Translate the phrase "in 3 years" into algebraic terms
Semenov [28]

Answer:

In three years can be into algebraic terms as:  3 + x. Where 'x' comes to be today's age.

For example, my age in three years will be:

If I'm 24 years right now, My age in three years = 3 + x ⇒ My age in three years = 3 + 24 = 27.

Please help me with precal
Doss [256]

Consider the function f(x)=\sqrt{x}. This function has:

  • the domain x\in [0,\infty);
  • the range y\in [0,\infty).

If the domain of unknown function is [a,\infty), then x\ge a or x-a\ge 0. This means that you have \sqrt{x-a} as a part of needed function.

If the range of unknown function is [b,\infty), then y\ge b. This means that you have to translate function b units up and then the expression of the function is

y=\sqrt{x-a}+b.

Answer: correct choice is B.
