In triangle MNP, what is the measure of angle N?

Answer:

The population will reach 20,400 after 6 years.

Step-by-step explanation:

Exponential function:

[tex]y(t)=y_0(1+r)^t[/tex]

y(t)= Population after t years

[tex]y_0[/tex] = initial population

r= rate of grow

t= time.

A town has a population of 17,000 and grows at a rate 3% every year.

y(t)= 20,400, [tex]y_0[/tex] = 17,000, r=3%=0.03, t=?

[tex]20,400=17,000(1+0.03)^t[/tex]

[tex]\Rightarrow \frac{20,400}{17,000}=(1.03)^t[/tex]

[tex]\Rightarrow \frac{102}{85}=(1.03)^t[/tex]

Taking ln function both sides

[tex]\Rightarrow ln|\frac{102}{85}|=ln|(1.03)^t|[/tex]

[tex]\Rightarrow ln|\frac{102}{85}|=t\ ln|(1.03)|[/tex]

[tex]\Rightarrow t=\frac{ln|\frac{102}{85}|}{\ ln|(1.03)|}[/tex]

⇒ t = 6 year.

The population will reach 20,400 after 6 years.

m = the number of miles driven

Company A cost = 76    

[they charge $76 for unlimited mileage, so they don't charge by the miles driven]

Company B cost =  0.70m + 55  

[they charge an initial fee of $55 plus $0.70 per mile(m)]

For what mileages will Company A charge less than Company B?

Company A cost < Company B cost  ----->   76 < 0.70m + 55      

To solve for m, isolate/get the variable "m" by itself in the inequality:

76 < 0.70m + 55     Subtract 55 on both sides

76 - 55 < 0.70m + 55 - 55

21 < 0.70m     Divide 0.70 on both sides to get "m" by itself

[tex]\frac{21}{0.70} <\frac{0.70m}{0.70}[/tex]

30 < m      [m is any number greater than 30]

Company A will charge less than Company B for mileages over/greater than 30.

Final answer:

Company A will charge less than Company B when more than 30 miles are driven; the inequality used to determine this is 76 < 55 + 0.70m, and after solving, it shows that m > 30.

Explanation:

To find out for what mileages Company A will charge less than Company B, we need to set up an inequality based on the given price structures for both companies:

Company A charges a flat rate of $76 per day, regardless of mileage.

Company B charges an initial fee of $55 plus $0.70 per mile driven.

The inequality to represent this scenario is:

76 < 55 + 0.70m

To solve for m (the number of miles driven), we subtract 55 from both sides:

21 < 0.70m

Then, divide both sides by 0.70 to isolate m:

m > 30

So, Company A will charge less than Company B when Bob drives more than 30 miles.

We can see that b1 = 18, b2 = 24, and h = 5

So, we can just substitute these in.

A = 1/2(18 + 24)5

A = 1/2 * 42 * 5

A = 21 * 5

A = 105

So, the answer is C. 105 sq cm

Step-by-step explanation:

M is the mid point of AB

here given A ( - 7 , -7) and M ( -6 , -1) Let the coordinates of point B be ( x1, y1)

Now

( - 6 , -1 ) = {( x1 - 7)/ 2 , ( y1 - 7) / 2}

Equating

-6 = x1 -7 -1 = y1 - 7

2. 2

-12 = x1 - 7. -2 = y1 - 7

x1 = -12 +7. y1 = -2 +7

Therefore x1 = - 5. Therefore y1 = 5

Therefore the coordinates of B is ( -5 , 5)

Answer:

the coordinates of B is ( -5 , 5)

As you can see, the peak occurs at (2,6). That means that all values below 6 are in the range.

Answer:

$3.94

Step-by-step explanation:

You will need to use the compound interest formula for this.

[tex]P(1+\frac{r}{n} )^{nt}[/tex]

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

Your equation will look like this:

[tex]3.31(1+\frac{.0088}{1} )^{20}[/tex] = 3.94

The slope-intercept form of the equation 4x + 3y = -3 is y = -4/3x - 1. The slope of the line is -4/3 and the y-intercept is -1.

The question asks to convert the equation 4x + 3y = -3 into slope-intercept form, and simplify all fractions. The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept.

To transform the given equation into this form, we need to express it in terms of y. Here are the steps:

In this equation, the term -4/3 is the slope and the -1 is the y-intercept. That means the line decreases for every 4 units in the y-axis when it increases 3 units in the x-axis.

Answer:

Step-by-step explanation:

The division problems 123.4/9.2 and 71.9/6.5 have an estimated quotient of 12 by considering 123.4 as 120, 9.2 as 10, 71.9 as 70, and 6.5 as 6.

The division problems with an estimated quotient of around 12 will be the ones where you divide a number close to 120 by 10. In this case, it comes to be 123.4/9.2 and 71.9/6.5. To estimate the quotient, you can consider 123.4 as approximately 120 and 9.2 as approximately 10. Similarly, 71.9 can be considered as approximately 70 and 6.5 as approximately 6. When you divide these estimate numbers, both quotients are close to 12.

Estimation is a useful skill in Mathematics that allows you to simplify complex problems and get close to the exact answer. It's particularly helpful in situations where you only need a rough estimate and not the exact figure.

1 hour = $10 bcas each piece you make is $2

40 hours = $400 because you get $10 per week

Step-by-step explanation:

S x H  = (1 x 5 x 2) x 40

The volume of the pyramid is  167.6 cube inch (approx).

Step-by-step explanation:

Given,

Each length (l) of the base of the pyramid = 8.3 in

Height(h) of the pyramid = 7.3 in

To find the volume of the pyramid.

Formula

Volume of the pyramid = [tex]\frac{1}{3}[/tex]×area of the base×height

Area of the base = l²

Now,

The volume of the pyramid =  [tex]\frac{1}{3}[/tex]×l²×h

=  [tex]\frac{1}{3}[/tex]×8.3²×7.3 cube inch = 167.6 cube inch (approx)

The volume of the pyramid is calculated using the formula for a pyramid's volume, V = (1/3)bh, with a base area of 68.89 in² and height of 7.3 in, which gives a volume of approximately 167.5 in³.

To find the volume of a pyramid with a square base, we can use the formula V = (1/3)bh, where b is the area of the base and h is the height of the pyramid. First, calculate the area of the square base by squaring the side length: b = s² = 8.3 in × 8.3 in = 68.89 in². Next, use this base area in the formula to get the volume: V = (1/3) × 68.89 in² × 7.3 in.

Doing the calculation, we find that V = (1/3) × 68.89 in² × 7.3 in = 167.4757 in³. To round to the nearest tenth, the volume of the pyramid is approximately 167.5 in³.

Answer:

75 gophers (about)

Step-by-step explanation:

We will use continuous compounding interest formula:

[tex]P(t)=P_0e^{rt}[/tex]

Where

P(t) is final value (at time t)

P_0 is initial value

r is the compounding rate

t is the time period

Given:

P(t) = 78

r is 1.5% or 1.5/100 = 0.015

t is 3

We solve for P_0, what we want, using algebra as shown below:

[tex]P(t)=P_0e^{rt}\\78=P_0e^{(0.015)(3)}\\78=P_0e^{0.045}\\\frac{78}{P_0}=e^{0.045}\\\frac{78}{P_0}=1.0460\\P_0=74.57[/tex]

So, the initial population was 75 gophers.

The 75 gophers were on the ranch at the beginning of the 3 years according to the exponential growth function.

To solve this problem, we can use the following exponential growth function:

P(t) = P_0 * e^(rt)

where:

P(t) is the population at time t

P_0 is the initial population

r is the annual growth rate

t is the time in years

We know that the population after 3 years is 78 gophers, and the annual growth rate is 1.5%. We want to find the initial population, P_0.

So, we can plug in the following values into the exponential growth function:

P(3) = 78 = P_0 * e^(0.015 * 3)

Dividing both sides by e^(0.015 * 3), we get:

P_0 = 78 / e^(0.015 * 3)

Using a calculator, we can evaluate P_0 to be approximately 75.0.

Rounding up to the nearest whole number, we get an initial population of 75 gophers.
