$85000 was paid at a short term note at 10% interest while $75000 was paid at a long term note at 7% interest.

An equation is an expression that shows the relationship between two or more variables and numbers.

Let x represent the amount of fund at 10% and y represent the amount of fund at 7% interest, hence:

x + y = 160000   (1)

Also:

0.1x + 0.07y = 13750    (2)

From both equations:

x = 85000 and y = 75000

$85000 was paid at a short term note at 10% interest while $75000 was paid at a long term note at 7% interest.

By evaluating in x = π/3, we conclude that the correct option is C.

By looking at the graph, we can see that the function becomes zero when:

x = π/3

Now, this is really trivial.

Just evaluate the four options in x = π/3, and see which ones become equal to zero, and discard the others.

By doing that, you will see that the only option that becomes zero when evaluated in x = π/3 is option C.

Answer:

x = 9 & y = 29

Step-by-step explanation:

Since we know that 7x is next to 117, that area will be equal to 180*,

7x + 117 = 180

7x = 180-117

7x=63

x=9

to find y, you can use the same method, just by finding the other angle inside. 53+7(9) + z = 180

53+63 = 180

116+z = 180

z = 180-116

z = 64.

Then we do

4y + 64 = 180

4y = 180-64

4y=116

y = 29

Option 1 is correct. The point T is the number of books and their cost where the subscription with the annual fee costs less.

At y1 = 96

Answer:

(x/2 , 17/2)

Step-by-step explanation:

To find a midpoint, you average the x's and average the y's. Average them by adding the x-coordinates and divide by 2. Same with the y's.

The x's are x for P1 and 0 for P2.

x+0 / 2

=x/2

This will be the x-coordinate of the midpoint. Then for the y, use 8 and 9, the y's.

8+9 / 2

= 17/2

This will be the y-coordinate of the midpoint.

The midpoint is:

(x/2 , 17/2)

You could also divide 17/2 and get 8.5 then the midpoint would be:

(x/2 , 8.5)

Answer:

10.4

Step-by-step explanation:

So an exponential equation with a decay can be expressed as: [tex]f(x)=a(1-r)^t[/tex] where r is the decay rate. In this case is decreasing at 4% each year, this means that the r is equal to 0.04 (divide the percent by 100 to convert to decimal). So the equation is going to be: [tex]f(x)=a(0.96)^t[/tex]. The reason this works is because whenever you decrease by x%, the new value is (1-x)%, which is expressed in the formula. But the reason the exponent is there is because after 1 year it's going to be 0.96a, but after two years, it's going to be 0.96 the previous year which is 0.96a, so after two years it's going to be 0.96(0.96a), and then the next year it's 0.96 of the second year, which is then 0.96(0.96(0.96a))... and so on. So the amount of 0.96 increases as t increases. the a is going to be the initial amount, since then t=0, 0.96^0 will be equal to 1, which makes the expression a(1), which is just a. So this gives you the complete equation: [tex]p(x)=13000(0.96)^t[/tex]

Now to find when it's equal to 8,500 you need to start by setting it equal to 8,500 so I'll work through each step

Original Equation:

[tex]p(x)=13000(0.96)^t[/tex]

Set the equation equal to 8,500

[tex]8500=13000(0.96)^t[/tex]

Divide both sides by 13,000

[tex]0.653846\approx 0.96^t[/tex]

Rewrite in logarithmic form

[tex]log_{0.96}0.653846=t[/tex]

If you're calculator allows you to enter the base when calculating log, but this expression into your calculator to calculate the value of t, otherwise use the change of base formula

[tex]\text{change of base formula: }log_ba = \frac{log(a)}{log(b)}[/tex]

B. )The graph of g(x) is a translation of the graph of f(x) right 6 units.

Step-by-step explanation:

When a positive number is directly added to an "x" variable (usually inside of parentheses), the graph is shifted to the left that many units.

When a negative number is directly added to an "x" variable, the graph is shifted to the right that many units.

A graph shifts up or down when a positive or negative number is added to the overall function. For example, if the -6 were outside of the parentheses, the graph would be translated 6 units downwards.

9680 smart phones of total 20465 sold smart phones would be made by Apple.

Percentage is a mathematical measurement of any mathematical quantity or number or another measurement out of a total of 100.

Here given that in the US 47.3% of smart phones sold are made by Apple.

And in one day 20465 phones are sold.

So,

Out of 100 sold smartphones, 47.3 phones are made by Apple.

then out of 1 sold smartphone 47.3/100 phones are made by Apple.

Hence out of 20465 smartphones (10465*(47.3/100)) = 9679.945 phones are made by Apple.

Since number of sold smart phone cannot be in decimal number in real, it always a whole number.

An SUV model's monthly sales are anticipated to rise at a rate of

[tex]S'(t)=-24^{1/3}[/tex] SUVs each month, where "t" denotes the number of months and "S(t)" denotes the monthly sales of SUVs. When monthly sales of 300 SUVs are reached, the business intends to discontinue producing this model.

Find S if monthly sales of SUVs are 1,200 at time t=0 (t). How long will the business keep making this model?

Given [tex]S'(t)=-24^{1/3}[/tex] ... ... (1)

Condition (1) at t=0; s(t) =1200

We find S(t)=300 then t=?

a) We find S(t)

from [tex]S'(t)=-24^{1/3}[/tex]

[tex]\implies \frac{dS(t)}{dt}=-24t^{1/3} ~~[\because X'(t)=\frac{dX}{dt} \\\implies dS(t) = -24t^{1/3}dt\\[/tex]

On Integrating both sides

[tex]S(t)=-18t^{4/3}+c ~...~...~(2)[/tex]

Now, at t=0 then S(t)=1200

So, from (2)

1200=0+c

⇒c=1200

[tex]\therefore[/tex]from eq (2)

[tex]S(t)=-18t^{4/3}+1200 ~...~...~(3)[/tex]

b) Considering that the firm intends to cease production of this model once monthly sales exceed 300 SUVs.

So, take S(t)=300

from eq (2) [tex]300=-18t^{4/3}+1200[/tex]

[tex]t^{4/3}=\frac{1200-300}{18}\\=\frac{900}{18}=50\\\implies t=50^{3/4}\\\implies t=18.8030[/tex]

Answer:

The last one [tex](x=11.3, y=8)[/tex].

Step-by-step explanation:

1) There are three trigonometric ratios for right-angled triangles.

[tex]sin()=\frac{opposite}{hypotenuse}\\cos()=\frac{adjacent}{hypotenuse}\\tan()=\frac{opposite}{adjacent}[/tex]

In a right triangle, the hypotenuse, h, is the side opposite the right angle. Relative to the acute angle θ, check the attachment, the legs are called the opposite side, o, and the adjacent side a.

2) In this case, we are given a length and an angle to find x and y.

Let's find x first. To find x we need to use [tex]sin()=\frac{opposite}{hypotenuse}[/tex].

[tex]sin(45)=\frac{8}{x}\\sin(45)x=8\\x=\frac{8}{sin(45)} \\x=11.31[/tex]

Find y.

Notice that, we can use the Pythagorean Theorem [tex](c^2=a^2+b^2)[/tex] to find y.

[tex]c^2=a^2+b^2[/tex]

[tex]11.31^2=8^2+b^2\\11.31^2 - 8^2 = b^2\\63.9161 = b^2\\\sqrt{63.9161} = b\\b = 7.99[/tex]

3) Round them off to the nearest tenth.

[tex]x=11.31\\x=11.3[/tex]

Hypotenuse is the baseline between the angles 36° and 54°.

Hypotenuse = 23/sin(36)

x = cos(36) × Hypotenuse

x = cos(36) × 23/sin(36) = cos(36)/sin(36) × 23 =

= 1/tan(36) × 23 = 23/tan(36) = 31.63686382... ≈

≈ 31.64

The approximate value of x in the diagram is,

⇒ x = 31.5

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The triangle is shown in figure.

Now, We can formulate;

⇒ tan 36° = 23 / x
