Answer 1

Answer: $\sqrt[n]{a^m}=a^(m)/(n)\n\n√(c^5)=\sqrt[2]{c^5}=c^(5)/(2)$

Answer 2

Answer: The square root of a number means you take that number to the 1/2 power. Our number is
c^5. Taking its square root, we have
(c^5)^(1/2). When you have exponents like that, you can multiply them together. For example,
(x^2)^3 = x^(2*3) = x^6

In this case, we have
(c^5)^(1/2) = c^(5*(1/2)) = c^(5/2)

If i have 2 apple and get 3 more then lose 2 how many do i have left

Answers

You have 2 apples, get 3 more, and then lose 2 of them.

So, you HAVE 2 apples, and if you get 3 more, you can add it to the 2.
$2 + 3 = 5$

In total at the moment, you have 5 apples. Now, you lose 2 more. We can subtract that from our total number of apples.
$5 - 2 = 3$

We now know that you are left with 3 apples.

2 apples + 3 apples - 2 apples = 3 apples

The perimeter of a rectangle is 34 units. Its width is 6.5 units. What is its length?

Answers

If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5

Given the function f(x)=-2x-1 and g(x)=-3x 4 which operation results in the smallest coefficient on the x term?a. two operations result in the same coefficient
b. subtraction
c. multiplication
d. addition

Answers

Answer:

Option (a) is correct.

The smallest coefficient on x - terms will be obtained by addition and multiplication of two given functions.

Step-by-step explanation:

Given: The function $f(x)=-2x-1$ and $g(x)=-3x+4$

We have to find the operation from the given options that results in the smallest coefficient on the x term .

Consider the given function $f(x)=-2x-1$ and $g(x)=-3x+4$

b) Subtraction

That is f(x) - g(x)

$f(x) -g(x)=-2x-1-(-3x+4)$

Apply plus - minus rule -(-a) = a , we have,

$f(x)-g(x)=-2x-1+3x-4$

$f(x)+g(x)=x-5$

Here, The coefficient of x is 1.

c) Multiplication

That is $f(x)\cdot g(x)=(-2x-1)\cdot (-3x+4)$

$\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$

$=\left(-2x\right)\left(-3x\right)+\left(-2x\right)\cdot \:4+\left(-1\right)\left(-3x\right)+\left(-1\right)\cdot \:4$

Simplify, we have,

$=6x^2-5x-4$

Here, The coefficient of x is -5.

d) Addition

That is f(x) + g(x)

$f(x)+g(x)=-2x-1+(-3x+4)$

Simplify, we have,

$f(x)+g(x)=-2x-1-3x+4$

$f(x)+g(x)=-5x+3$

Here, The coefficient of x is -5.

a) two operations result in the same coefficient.

When we add or multiply the two given function, we obtain the same coefficient of x that is -5

Hence, The smallest coefficient on x - terms will be obtained by addition and multiplication of two given functions.

Answer:

a. two operations result in the same coefficient

Step-by-step explanation:

Here, the given functions,

f(x) = -2x - 1,

g(x) = -3x + 4,

Subtracting,

Case 1 : f(x) - g(x)

-2x - 1 + 3x - 4 = x - 5

Case 2 : g(x) - f(x)

3x - 4 + 2x + 1 = 5x - 3

Coefficient of x = 1 or 5

Multiplication :

f(x)* g(x) = (-2x - 1) (-3x + 4) = 6x² - 8x + 3x - 4 = 6x² - 5x - 4

Coefficient of x = -5

Addition :

f(x) + g(x) = -2x - 1 - 3x + 4 = -5x + 3

Coefficient of x = -5

Thus, the least coefficient of x = -5

And, two operation ( multiplication and addition ) operations result in the same coefficient

OPTION a is correct.

What is an equation of the line that passes through (0,8) and (4,0)?

Answers

Answer: y=-2x+8

Step-by-step explanation:

To find the slope of the line, you would use $(y_(2)-y_(1) )/(x_(2) -x_(1) )$ . With the 2 points we are given , we can plug it into this equation to find the slope.

$(0-8)/(4-0) =(-8)/(4) =-2$

Now we know the slope is -2. To find the y-intercept, we know that the x value is 0. We are given that one of the points is (0,8). That means 8 is our y-intercept.

The final equation we get is y=-2x+8.

Answer:

y= -2×+8

Step-by-step explanation:

find m(slope)

y2-y1 over x2-x1

substitute using (0,8) and (4,0)

m=-2

y=mx+b

substitute x and y to find b using either (0,8) or (4,0)

0=-2(4) + b

0= -8 +b
