Answer:

280

Step-by-step explanation:

Month 1: 100 + 30 = 150

Month 2: +30

Month 3: +30

Month 4: +30

Month 5: +30

Month 6: +30

Total: 280

Hope this helps!

Answer:

$280

Step-by-step explanation:

For this problem, we simply need to take the initial cost of membership and add that to the reoccurring cost from a time period, in this case, 6 months.  So let's make an equation to represent this.

The initial cost is $100

The per month cost is $30

Total cost after 6 months = Inital cost + Per Month Cost * 6 months

Total cost = $100 + $30 * 6

Total cost = $100 + $180

Total cost = $280

Thus, a member will spend $280 after 6 months on the membership.

Cheers.

Answer:

The instantaneous rate of change as x approaches 3 is 18.

Step-by-step explanation:

From Differential Calculus and Geometry we remember that instantaneous rate of change of the function is represented by a tangent line, whose slope is determined by the first derivative of the curve. Let [tex]f(x) = 3\cdot x^{2}[/tex], the instantaneous rate of change of the function when x approaches 3 is deducted from the definition of derivative:

[tex]f'(x) = \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}[/tex] (1)

[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot (x+h)^{2}-3\cdot x^{2}}{h}[/tex]

[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot (x^{2}+2\cdot x\cdot h +h^{2})-3\cdot x^{2}}{h}[/tex]

[tex]f'(x) = \lim_{h\to 0} \frac{3\cdot x^{2}+6\cdot x\cdot h+3\cdot h^{2}-3\cdot x^{2}}{h}[/tex]

[tex]f'(x) = \lim_{h\to 0} \frac{6\cdot x\cdot h +3\cdot h^{2}}{h}[/tex]

[tex]f'(x) = \lim _{h\to 0} (6\cdot x+3\cdot h)[/tex]

[tex]f'(x) = 6\cdot x \cdot \lim_{h\to 0} 1 + 3\cdot \lim_{h\to 0} h[/tex]

[tex]f'(x) = 6\cdot x[/tex] (2)

If we know that [tex]x = 3[/tex], then the instantaneous rate of change as x approaches 3 is:

[tex]f'(3) = 6\cdot (3)[/tex]

[tex]f'(3) = 18[/tex]

The instantaneous rate of change as x approaches 3 is 18.

Answer:

The probability of a randomly chosen person being from California is 0.111.

The probability of a randomly chosen person not being from California   is 0.889.

Step-by-step explanation:

The odds of a person, selected from the US population, living in California is 1 to 8.

That is:

[tex]\text{Odds}(\frac{\text{Lives in California}}{\text{Does not Lives in California}})=\frac{1}{8}[/tex]

Compute the probability of a randomly chosen person being from California as follows:

[tex]P(\text{Lives in California})=\frac{\text{Odds}(\text{Lives in California})}{\text{Odds}(\text{Lives in California})+\text{Odds}(\text{Does not Lives in California})}[/tex]

                                  [tex]=\frac{1}{1+8}\\\\=\frac{1}{9}\\\\=0.111[/tex]

The probability of a randomly chosen person being from California is 0.111.

Compute the probability of a randomly chosen person not being from California as follows:

[tex]P(\text{Love in California})=1-P(\text{Does not Love in California})[/tex]

                                  [tex]=1-0.111\\\\=0.889[/tex]

Thus, the probability of a randomly chosen person not being from California   is 0.889.

Answer:

so what is the question?

Answer:

The values of a and b are:

Step-by-step explanation:

Given the exponential model

[tex]y=a\cdot \:b^x[/tex]

Given the points

(0, 2) and (3, 128)

We know that the y-intercept of [tex]y=a\cdot \:b^x[/tex] is (0, a).

so

a = 2

putting x = 3, y = 128 and a = 2

[tex]y=a\cdot \:b^x[/tex]

[tex]128=2\cdot \:b^3[/tex]

Switching sides

[tex]2b^3=128[/tex]

[tex]\frac{2b^3}{2}=\frac{128}{2}[/tex]

[tex]b^3=64[/tex]

Taking the real value such as:

[tex]\mathrm{For\:}x^3=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt[3]{f\left(a\right)}[/tex]

so

[tex]b=\sqrt[3]{64}[/tex]

[tex]b=\sqrt[3]{4^3}[/tex]

[tex]b=4[/tex]

Therefore,

Step-by-step explanation:

We are required to find 6% of 50

To write it mathematically,

50 * 6%

Now, 6% can be rewritten as 6/100 because it tells us: '6 out of 100' and that is what percentage does

= 50 * [tex]\frac{6}{100}[/tex]

= [tex]\frac{300}{100}[/tex]

= 3

Hence, 6% of 50 is 3

Answer:

68≥25+3x

x≥15

Step-by-step explanation:

the overall goal is to have $68, so the goal needs to be less then or equal to the weekly $25 plus each additional subscription at $3 (x represents the needed amount of subscriptions he sells) the inequality would look something like 68≥25+3x because he wants the money this week.

to solve the inequality you would subtract the 25 from the 68, leaving you with 43≥3x as the new inequality, now you need to divide both sides by 3. Which comes out to 14.33333..... since we cant sell a fraction of a subscription you must round up giving you the new inequality of x≥15

this means that in order for Andre to get the cleats this week, he must sell at least 15 subscriptions

hope this helped

a.)   25x + 3y ≥ 68

b.) x = 1, y = 43

c.) As x increases, y decreases

A linear inequality is a mathematical relation which gives the range of values a variable or a function can take.

Given,

Wage per week= $25

Subscription earning = $3

Let x and y be the number of weeks and number of subscriptions.

Therefore, 25x + 3y ≥ 68

Hence, 25x + 3y ≥ 68 is the required inequality.

Let x = 1

Therefore  minimum value of y = 43.

Answer:

$ 64

Step-by-step explanation:

Let Steph paid $x to buy the used bicycle.

After restoring, she marked it up by 1/4 of the price she paid.

So, the marked price [tex]= x +\frac 1 4 x = \frac {5x}{4}[/tex]

As she sold the bicycle for the marked up price to $80.

So, [tex]\frac {5x}{4} = 80[/tex]

[tex]\Rightarrow x = \frac {80\times 4}{5}\\\\\Rightarrow x = 64.[/tex]

Hence, she paid $ 64 for the bicycle.

Step-by-step explanation:

Answer:

x = 16

m<Y = 34°

Step-by-step explanation:

∆XYZ is an isosceles ∆. An isosceles ∆ has two equal sides, as well as the bases of the isosceles triangle are congruent. In this case, therefore:

<X = <Z

(6x - 23)° = (4x + 9)

Solve for x

6x - 23 = 4x + 9

Collect like terms

6x - 4x = 23 + 9

2x = 32

Divide both sides by 2

x = 16

m<Y = 180° - (m<X + m<Z) (sum of ∆)

m<Y = 180 - ((6x - 23) + (4x + 9))

Plug in the value of x

m<Y = 180 - ((6(16) - 23) + (4(16) + 9))

m<Y = 180 - (73 + 73)

m<Y = 34°
