Answer:

8 Seconds

Step-by-step explanation:

Since Jimmy runs 8 meters per second, we can multiply 8x8 to find where he will be after 8 seconds.

8x8 = 64

Since Jimmy's little brother runs 3 meters per second, we can multiply 3x8 to find where he will be after 8 seconds.

3x8 = 24

But, remember, Jimmy's little brother had a 40 meter head start. So we have to add 40 to his total.

24+40 = 64

Since Jimmy and his little brother's totals are both the same, Jimmy will catch up to his little brother after 8 seconds.

Answer:

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

Step-by-step explanation:

To find slope using coordinates, use the formula above.

[tex](4, - 3) \: (0, - 2)→ \frac{ - 2 - ( - 3)}{0 - 4}→ \frac{ - 2 + 3}{ - 4} → - \frac{1}{4} [/tex]

Now, using the [tex]y = mx + b[/tex] formula, plug in [tex] - \frac{1}{4} [/tex] as [tex]m[/tex] (slope) and either coordinate as the [tex]x[/tex] and [tex]y[/tex] values. It looks like this:

[tex] - 3 = - \frac{1}{4}(4) + b[/tex]

To solve for [tex]b[/tex], continue to use PEMDAS.

[tex] - 3 = - \frac{1}{4}(4) + b→ - 3 = - 1 + b→ - 2 = b[/tex]

Now use [tex]m[/tex] and [tex]b[/tex] to solve for your equation:

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

The answer is C.

Answer:

$12

Step-by-step explanation:

Answer:

61 is the rate at which the population changes every year

Step-by-step explanation:

Given

[tex]2000 - 61k = 48[/tex]

Required

Interpret 61

A linear equation has the form:

[tex]y = mk + b[/tex]

or

[tex]b + mk = y[/tex]

Where m is the rate

By comparison:

[tex]mk = -61k[/tex]

[tex]m = -61[/tex]

Hence, 61 represents the rate at which the population changes yearly.

The negative sign implies that the populatiin reduces

Answer:

Lina should make $471.75 a month.

Step-by-step explanation:

If Lina makes $9.25 an hour and she works for 15 hours a week then you multiply those two numbers together. The resulting number is $555. Then you'll multiply that by .15 to find 15% of that number which is 83.25. After, you'll subtract that from $555, which gives you $471.75.

Answer:

The weight of dogs x = 38pounds

Step-by-step explanation:

Step(i):-

Given that the mean weight of a group of dogs

       μ = 38 pounds

Let 'x' be the weight of dogs

Let 'x' be the random variable in normal distribution

Given that z-score is zero

Step(ii):-

we know that the z-score

                   [tex]Z = \frac{x-mean}{S.D}[/tex]

            ⇒  [tex]0 = \frac{x-38}{S.D}[/tex]

            ⇒ 0 = x-38

           ⇒  x-38 = 0

          ⇒   x =38

Final answer:-

The weight of dogs x = 38pounds

Answer:

86 or 32, depending on the correctness of the syntax

Step-by-step explanation:

We use PEMDAS:

Parentheses: 4(2)5 2-6/(-3)

Exponents: I'm assuming that all the syntax is correct (so no exponents).

Multiplication and Division: 40*2+6 = 80 + 6

Addition and Subtraction: 86

If you copy+pasted this expression, then the original equation would have been: (4(8 − 6)^5)/(2 − 6 ÷ (−3)). We can use PEMDAS:

Parentheses: (4(2)^5)/(2 - 6 ÷ (−3))

We now have the following fraction: 128/4

That simplifies to 32

Answer:

The inverse of x² +1 is:  

[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]

Step-by-step explanation:

Given

y = x² + 1,  x>0

We know that A function g is the inverse of a function f if for y = f(x), x = g(y)

y = x² +1

Replace x with y

x = y² + 1

solve for y

y² = x - 1

Taking square root

[tex]y=\:\sqrt{x-1},-\sqrt{x-1}[/tex]

Thus, the inverse of x² +1 is:  

[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]

Answer:

the first one is 2/4 and 3/6

the second one is 4/6 and 6/8  and the equation is

3/4 times 4/6 = .5

Step-by-step explanation:

Answer:

y intercept (-6,0), x-intercept (0,-8) : [tex]y = \frac{-4}{3}x -8[/tex]

y intercept (0,-6), x-intercept (-2,0): [tex]y = -3x -6[/tex]

y intercept (0,8), x-intercept (1.6,0): [tex]y = -5x + 8[/tex]

y intercept (0,7), x-intercept (-1.4,0): [tex]y = 5x + 7[/tex]

Step-by-step explanation:

y = mx + b

*note: b is the y intercept

1. y intercept (-6,0), x-intercept (0,-8)

[tex]m = \frac{-8 - 0}{0 - (-6)}= \frac{-8}{6} = \frac{-4}{3}\\y = \frac{-4}{3}x + b\\y = \frac{-4}{3}x -8[/tex]

2.y intercept (0,-6), x-intercept (-2,0)

[tex]m = \frac{0 - (-6)}{-2 - 0} = \frac{6}{-2} = -3\\y = -3x + b \\y = -3x -6[/tex]

3. y intercept (0,8), x-intercept (1.6,0)

[tex]m = \frac{0 - 8}{1.6 - 0}= \frac{-8}{1.6} = -5\\y = -5x + b\\y = -5x + 8[/tex]

4. y intercept (0,7), x-intercept (-1.4,0)

[tex]m = \frac{0 - 7}{-1.4 - 0} = \frac{-7}{-1.4}= 5 \\y = 5x + b\\y = 5x + 7[/tex]

Answer:

2%

Step-by-step explanation:

To solve this problem, a proportion would be best! We can set up the first fraction with the two numbers given to us. We'll use t to represent tax, and w to represent the whole. The first fraction will look something like this:

[tex]\frac{9.80t}{490w}[/tex]

Next, we'll set up our second fraction using knowledge of percents. Every percent is a part of 100%, so we can use 100 as our percent to represent the whole. Since we are solving for the percent that is out of 100, we'll use x to represent it. The final proportion should look like this:

[tex]\frac{9.80t}{490w} = \frac{x}{100w}[/tex]

To solve, we just need to cross-multiply and divide! First, multiply 9.80 by 100 to get 980. Finally, divide 980 by 490 to get a final answer of 2%. The sales tax rate is 2%. The final calculations are as follows:

9.80 X 100 = 980

980 / 490 = 2 or 2%

Answer:

The first option (the uppermost) is correct.

Step-by-step explanation:

When you multiply 1/2 by 3/4, you obtain the result of (1x3) / (2x4).

Simplifying, this gives us the result: 3/8, which is represented by the first choice.

Answer:

Its 2 x radius

Step-by-step explanation:

Answer:

Twice the radius length.

Step-by-step explanation:

Generally, the diameter is the length of a line that extends from one point on a circle to another point on a circle as long as that line passes through the center of the circle. Essentially, a diameter, in short, is twice the length of the radius of a circle.
