Answer:

  multiply their coefficients, use the base with the sum of exponents

Step-by-step explanation:

The coefficients multiply. The base gets an exponent that is the sum of the exponents of the factors.

  (a·x^b)(c·x^d) = ac·x^(b+d)

_____

If you remember that an exponent is simply an indicator of the number of times the base is a factor, this should be fairly clear. The usual associative and commutative properties of multiplication apply.

Example

  5x^2 · 7x^3= 5·x·x·7·x·x·x

  = 5·7·x·x·x·x·x

  = (5·7)(x^(2+3))

  = 35x^5

Answer:

8.142

Step-by-step explanation:

Answer: You can decide to choose any of these but they're all the same!

8 R 1

Decimal form:

8.1 (if you round it to the nearest tenths).

8.14 (if you round it to the nearest hundredths).

8.143 (if you round it to the nearest thousandths).

Step-by-step explanation:

When you begin the division, you have to think of what is the highest number that is less than 57 that is a multiple of 7, that number is 56. 56/7 is 8 which is where I got the 8.

57 - 56 = 1 which is the remainder.

If you want to write it in decimal form, you divide the 1 by 7 and since you'll get a decimal number with 0.14.. you had that number to 8, which gives you your answer in decimal form!

Hope that helped!

Answer:

I think it's 15 Quarters.

Step-by-step explanation:

The required number of dimes and quarter Whitney has is 11 and 9 respectively.

Given that,
Whitney has 20 coins in her purse. Some are quarters and some are dimes. The total value of the coins is $3.35. The number of quarters Whitney have is to be determined.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Let the number of dimes be x and the number of quarters be y,
According to ot the question,
x + y = 20
x = 20 - y - - - - (1)
and
0.1x + 0.25y = 3.35
From equation 1
0.1[20 - y] + 0.25y = 3.35
y = 9
Now,
x = 20 - 9
x = 11

Thus, the required number of dimes and quarters Whitney has is 11 and 9 respectively.

Answer:

[tex]A=1347.7\ cm^2[/tex]

Step-by-step explanation:

Given that,

Radius of a cone, r = 13 cm

Slant height of the cone, l = 20 cm

We need to find the surface area of the cone. The formula for the surface area of the cone is given by :

[tex]A=\pi rl +\pi r^2[/tex]

Put all the values,

[tex]A=\pi r(l + r)\\\\A=\pi \times 13(20 + 13)\\\\A=1347.7\ cm^2[/tex]

So, the surface area of the cone is [tex]1347.7\ cm^2[/tex].

Answer:

X = 2

Step-by-step explanation:

12x - 4 = 4(2x + 1) (multiple 2x and 1 by 4)

=> 12x - 4 = 8x + 4

=> 12x - 8x = 4+4 (and the alike terms together)

=> 4x = 8

=> x = 8/4 ( divide 8 and 4 by 4)

=> x = 2/1

=> x = 2

The ranges are:

f(x): {y | y ≤ infinity}

g(x): {y | y ≤ infinity}

A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

For the function f(x) = (4/5)x, any input value of x will be multiplied by 4/5 and produce a corresponding output value y.

Since the fraction 4/5 is less than 1, the output values of f(x) will always be smaller than the input values of x.

Therefore, the range of f(x) will be all real numbers less than or equal to the greatest possible output value.

The greatest possible output value will occur when x is the greatest possible input value, which is infinity. So, the range of f(x) is:

f(x): {y | y ≤ infinity}

For the function g(x) = (4/5)x + 6, any input value of x will be multiplied by 4/5, then 6 will be added to the result to produce a corresponding output value y.

The fraction 4/5 is less than 1, so the output values of g(x) will always be less than the input values of x plus 6.

Therefore, the range of g(x) will be all real numbers less than or equal to the greatest possible output value, which occurs when x is infinity. So, the range of g(x) is:

g(x): {y | y ≤ infinity}

Answer:

Zeros → (-2, 0) and (4, 0)

Step-by-step explanation:

Equation of the graph has been given as,

y = [tex]\frac{1}{2}x^{2} -x-4[/tex]

For zeros of the function,

y = 0

Therefore, [tex]\frac{1}{2}x^{2} -x-4=0[/tex]

By solving the equation algebraically,

x² - 2x - 8 = 0

x² - 4x + 2x - 8 = 0

x(x - 4) + 2(x - 4) = 0

(x + 2)(x - 4) = 0

x = -2, 4

Therefore, coordinates of the zeros will be (-2, 0) and (4, 0).

Let's confirm the zeros (x-intercepts) from the graph attached,

Coordinates of the x-intercepts are,

(-2, 0) and (4, 0)

I do not know what you just said so I assume your asking if 3 is less than 5 and yes 3 is less than 5

Answer:

Step-by-step explanation:

This can happen because of the timestamp on the toll card. When you pass through the initial entrance point the timestamp marks the exact moment you passed. When you pass through the exit toll point the individual subtracts the current time from the time you entered the initial toll entrance. From this, he can easily determine the average speed that you were driving at. If the average speed is higher than the speed limit, it means that at some point between the two toll booths you were speeding and therefore they can give you a speeding ticket.

Answer: [tex]x = 2\sqrt{15}[/tex]

Step-by-step explanation:

[tex]\dfrac{15}{x}=\dfrac{x}{4} \\\\ x \times x = 15 \times 4\\x^{2} =60\\x=\sqrt{60} =2\sqrt{15}[/tex]

Step-by-step explanation:

First, convert 2,300 ounces into pounds.

2,300oz. - 143.75 pounds

You then need to add the pounds from the pilot and Tristan's.

143.75 + 200 = 343.75

If the hot air balloon can hold 350lbs, then both Tristan and the pilot can ride it together. The reason why they can ride it together is because 343.75 pounds is less than what the hot air balloon can originally hold, which is 350lbs.

Answer:

b is the answer

Step-by-step explanation:

the graph of f(x)=0.5x is replaced by the graph of g(x) = 0.5x-k

if g(x) is obtained by shifting f(x) down by 5 units,

then the graph of f(x) = 0.5x is replaced by the graph of g(x) = 0.5x-5

so k = 5 units
