= Solution
= 13 - 6 (- 4 ) ² + 8
Now...remove the negative number...because negative number raise to even powers are positive...
= 13 - 6 × 4² + 8
= 13 - 96 + 8
= 13 + 8 - 96
= 21 - 96

What percent of 6 is 9?
Answer:
150%
Step-by-step explanation:
half of 6 is three, and 9 has a value of 3 more than 6. meaning that 9/6 = 150%
Answer: [tex]150[/tex]% [tex]([/tex][tex]0.54[/tex][tex])[/tex]
Step-by-step explanation:
For fraction: divide 6 by 100 and remove the % sign.
{[tex]6[/tex]}% [tex]=\frac{6}{100}[/tex]
For decimal: move the decimal point 2 places to the left and remove the % sign.
{[tex]6[/tex]}% [tex]=0.06[/tex]
[tex]100[/tex]% [tex]=9[/tex]
[tex]\frac{6}{100}[/tex] × [tex]9=0.06[/tex] × [tex]9=0.54[/tex]
[tex]6[/tex]% [tex]of~9~is~0.54[/tex]
What is the slope of a line parallel to the line whose equation is x + y = -7. Fully
simplify your answer.
Answer:
slope = - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x + y = - 7 ( subtract x from both sides )
y = - x - 7 ← in slope- intercept form
with slope m = - 1
Parallel lines have equal slopes
then the slope of a line parallel to it is - 1

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Let's get it solved ~
We have been given length and width of a rectangle in terms of x ~
that is :
length = x + 3width = x - 2Area of the rectangle is given ~ i.e 24 unit²
Area of rectangle in terms of x is :
[tex]\qquad \sf \dashrightarrow \:(x - 2) \sdot(x + 3) = 24[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{2} + 3x - 2x - 6= 24[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{2} +x - 6 - 24 = 0[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{2} +x -30= 0[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{2} + 6x - 5x - 30 = 0[/tex]
[tex]\qquad \sf \dashrightarrow \: {x}^{}( x + 6) - 5(x + 6)= 0[/tex]
[tex]f(x) = \begin{cases}x = - 6 \: \textsf{ \: if \:x + 6 = 0 } \\ \\ x = 5 \: \: \: \: \: \: \textsf{if \: x - 5 = 0} \end{cases}[/tex]
but since side of a rectangle can't be negative, we have to take value of x as 5
now, Perimeter of rectangle is ~
[tex]\qquad \sf \dashrightarrow \:2(width \: + \: length)[/tex]
[tex]\qquad \sf \dashrightarrow \:2(x - 2 + x + 3)[/tex]
[tex]\qquad \sf \dashrightarrow \:2(2x + 1)[/tex]
plug In the value of x ~
[tex]\qquad \sf \dashrightarrow \:2(2(5) + 1)[/tex]
[tex]\qquad \sf \dashrightarrow \:2(10 + 1)[/tex]
[tex]\qquad \sf \dashrightarrow \:2(11)[/tex]

Answer:
5, 18, 44, 96, 200
Step-by-step explanation:
Given
aₙ = 2(aₙ₋₁ + 4)a₁ = 5First term : 5
Second term : a₂ = 2(a₁ + 4)
a₂ = 2(5 + 4) = 2(9) = 18Third term : a₃ = 2(a₂ + 4) = 2(18 + 4) = 2(22) = 44
Fourth term : a₄ = 2(a₃ + 4) = 2(44 + 4) = 2(48) = 96
Fifth term : a₅ = 2(a₄ + 4) = 2(96 + 4) = 2(100) = 200
Hence, the first 5 terms of the sequence are :
5, 18, 44, 96, 200Answer:
5, 18, 44, 96, 200
Step-by-step explanation:
[tex]\textsf{Given sequence}: \quad a_n=2(a_{n-1}+4)[/tex]
[tex]\textsf{Given first term}: \quad a_1=5[/tex]
[tex]\implies a_1=5[/tex]
[tex]\implies a_2=2(a_{1}+4)=2(5+4)=2(9)=18[/tex]
[tex]\implies a_3=2(a_{2}+4)=2(18+4)=2(22)=44[/tex]
[tex]\implies a_4=2(a_{3}+4)=2(44+4)=2(48)=96[/tex]
[tex]\implies a_5=2(a_{4}+4)=2(96+4)=2(100)=200[/tex]
What is the simplified value of the exponential expression 16 superscript one-fourth? 2 4
For the exponential expression, [tex]16^{1/4}[/tex] the simplified value is 2.
How to simplify the exponential expression?
First, we need to remember a rule for exponential expressions, it says that:
[tex]x^{1/n} = \sqrt[n]{x}[/tex]
Then we can rewrite the given exponential expression as:
[tex]16^{1/4} =\sqrt[4]{16}[/tex]
So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.
We know that:
2*2 = 4
Then:
2*2*2*2 = 2⁴ = 4*4 = 16
Then we can conclude that:
[tex]16^{1/4} =\sqrt[4]{16} = 2[/tex]
So the simplified value of the exponential expression is 2.

By taking the product between the rate and the time, we will see that he does not finish the book.
Will he finish the book?We know that he can read 5 pages in 15 minutes. Then in one hour he can read 4 times that: 4*5 pages = 20 pages.
We conclude that Carter reads 20 pages per day, then, if he reads for 14 hours, then he reads a total of:
20*14 = 280
So he will read 280 pages in these 14 hours, which means that he will not finish the book.

What are the solutions to the equation?
x²-12x+36=4
Enter your answers in the boxes.
x1 =
x2=
The roots of this equation equation are:
x1 = 4
x2 = 8
This sentence given in the statement of this question is: Equation of the Second Degree. There are a few ways to solve it, but let's calculate by the factorization method.
Equation given: x² - 12x + 36 = 4
First, let's multiply the 12 and 36 term into factors (factoring):x² - 12x + 36 = 4
12x ➯ 2x . x6
36 ➯ 6²
x² - 2x . x6 + 6²
( x - 6 )² = 4
Now we remove the parentheses and we will transform the exponent 2 into the square root of its original number:( x - 6 )² = 4
x - 6 = ±√4
x - 6 = ±2
We will organize the equation in two forms, being: positive and negative:x - 6 = ±2
x - 6 = -2
x - 6 = +2
Finally, let's calculate the first degree equation:x - 6 = -2
x = -2 + 6
x = 4
x - 6 = +2
x = 2 + 6
x = 8
Therefore, the correct results of this equation, will be:
x1 = 4
x2 = 8

If the number of bacteria in a colony doubles every 475 hours and there is currently a population of 65 bacteria, what will the population be 950 hours from now???
The population (number of bacteria in the colony), 950 hours from that time, will be 260 bacteria
Determining the population of bacteriaFrom the question, we are to determine what the population will be after 950 hours
From the given information,
The number of bacteria in a colony doubles every 475 hours
The current population is 65 bacteria
∴ After 475 hours, the new population will be 2 × 65 bacteria
New population after 475 hours = 130 bacteria
After another 475 hours (that is, 950 hours from the initial time),
The population will be 2 × 130 bacteria = 260 bacteria
Hence, the population, 950 hours from that time, will be 260 bacteria
