Given the Trigonometric Functions:

$\begin{gathered} sec(948\text{\degree}) \\ \\ cos(-948\text{\degree}) \end{gathered}$

Using your calculator you get:

$sec(948\text{\degree})\approx-1.49$

By definition, Secant is negative in Quadrant III.

Finds its Reference Angle as follows:

$948\text{\degree}-5\cdot180\text{\degree}=48\text{\degree}$

Because:

$\frac{948}{180}\approx5$

Then, you get:

$=-sec\left(48\text{\degree}\right)$

Notice that:

$cos(-948\text{\degree})\approx-0.67$

Then, you can conclude that it is in Quadrant II.

Therefore its Reference Angle is:

$5\cdot180\text{\degree}-948\text{\degree}=-48$

So you can set up:

$=-cos\lparen-48)$

By definition:

$cos(-\theta)=cos\theta$

Therefore, you can rewrite it in this form:

$=-cos(48\text{\degree})$

Hence, the answer is:

$\begin{gathered} sec(48\text{\degree}) \\ \\ -cos(48\text{\degree}) \end{gathered}$

Given =(5,-2, 3) and >= (1, 1, 2) find an ordered triple that represents 3u - 2v.

Answers

The ordered triple representing $3u - 2v$ is $(13, -8, 5)$.

To find an ordered triple representing $3u - 2v$,

where $u = (5, -2, 3)$ and $v = (1, 1, 2)$,

we can perform the following operations:

$3u = 3(5, -2, 3)$

$3u = (15, -6, 9)$

$2v = 2(1, 1, 2)$

$2v = (2, 2, 4)$

Now, subtracting 2v from 3u gives:

$3u - 2v = (15, -6, 9) - (2, 2, 4)$

$3u - 2v = (15-2, -6-2, 9-4)$

$3u - 2v = (13, -8, 5)$

Therefore, the ordered triple representing 3u - 2v is (13, -8, 5).

PLEASE HELP!!! Given that x and y vary inversely and that y is 24 when x is 8, sketch a graph of this inverse variation function for x > 0.

Answers

Note that as x gets larger, y gets smaller, but the product xy remains constant at 192.

What is function?

In mathematics, a function is a relationship between two sets, called the domain and the range, such that each element of the domain corresponds to exactly one element of the range. A function takes an input value (or values) and produces an output value (or values) according to a specific rule or formula. The input values are the domain of the function, and the output values are the range of the function. Functions can be represented using equations, graphs, tables, or verbal descriptions. They are used to model relationships between variables in various fields of mathematics, science, engineering, economics, and many other areas.

Here,

If x and y vary inversely, this means that their product is a constant. We can use this fact to find the constant of proportionality k as follows:

k = xy

If we know that y is 24 when x is 8, we can substitute these values into the equation above to solve for k:

k = xy

= 8(24)

= 192

Now we can use this value of k to write the inverse variation function:

xy = 192

y = 192/x

To sketch a graph of this function for x > 0, we can plot a few points and connect them with a smooth curve. Here are some points we can use:

(x, y)

(1, 192)

(2, 96)

(4, 48)

(8, 24)

(16, 12)

(24, 8)

Step-by-step explanation:

the inside expression of an absolute value expression can be positive or negative, but the result is only the positive one.

therefore, for our example here the negative case would be

2.5x - 6.8 = -12.9

which gives us

2.5x = -6.1

x = -6.1/2.5 = -2.44

and the positive case would be

2.5x - 6.8 = 12.9

and that gives us

2.5x = 19.7

x = 19.7/2.5 = 7.88

The ESS Ravens bought pizza for $900 to sell at the football game. They kept 10 pizzas to feed the players after the game and sold the rest for $1040. There were 8 slices in each pizza. Their profit was 50 cents a slice.

a) How many pizzas were in the original order?

Answers

Answer: 45

Step-by-step explanation:

The total profit in all was $1040-900=\$ 140$.

The total profit per pizza was $(0.50)(8)=\$4$.

This means they sold $\frac{140}{4}=35$ pizzas.

Adding this to the 10 pizzas held back, there were $35+10=45$ pizzas in the original order.

There are 54 liters of water in the bath.

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

Hot tap:

5 ltr = 1 minute

Now,

He runs both taps for 6 minutes.

This means,

Amount of water in the bath after 6 minutes.

= 5 x 6 + 4 x 6

= 30 + 24

= 54 ltr

Now,

Then runs just the cold tap for 4 minutes.

This means,

Amount of water in the bath in the next 4 minutes.

= 54 + 4 x 4

= 54 + 16

= 70 ltr

x-intercept of 3 and y-intercept of 8
How do you write a lunar equation given this information and how do you write the equation in slope form

Answers

Answer:

y = -8/3x + 8

Step-by-step explanation:

Step 1: Identify which values we have and need to find in the slope-intercept form:

The general equation of the slope-intercept form of a line is given by:

y = mx + b, where

(x, y) is any point,m is the slope,and b is the y-intercept.

Since we're told that the y-intercept is 8, this is our b value in the slope-intercept form.

Step 2: Find m, the slope of the line:

Since the x-intercept is 3, the entire coordinates of the x-intercept are (3, 0)

Thus, we can find m, the slope of the line by plugging in (3, 0) for (x, y) and 8 for b:

0 = m(3) + 8

0 = 3m + 8

-8 = 3m

-8/3 = m

Thus, the slope is -8/3.

Therefore, the the equation of the line in slope-intercept form whose x-intercept is 3 and whose y-intercept is 8 is y = -8/3x + 8.

Optional Step 3: Check the validity of the answer:

We know that the entire coordinates of the x-intercept are (3, 0) and the entire coordinates of the y-intercept are (0, 8).

Thus, we can check that we've found the correct equation in slope-intercept form by plugging in (3, 0) and (0, 8) for (x, y), -8/3 for m, and 8 for b and seeing if we get the same answer on both sides of the equation when simplifying:

Plugging in (3, 0) for (x, y) along with -8/3 for m and 8 for b:

0 = -8/3(3) + 8

0 = -24/3 + 8

0 = -8 = 8

0 = 0

Plugging in (0, 8) for (x, y) along with -8/3 for m and 8 for b;

8 = -8/3(0) + 8

8 = 0 + 8

8 = 8

Thus, the equation we've found is correct as it contains the points (3, 0) and (0, 8), which are the x and y intercepts.

(d) now solve the linear equation in part (b), and find the solution that satisfies the initial condition in part (c).

Answers

The Bernoulli differential equation is a nonlinear ordinary differential equation of the form:

dy/dx + P(x)y = Q(x)y^n, where n ≠ 0, 1.

For n = 0 or n = 1, the equation is linear. For other values of n, a common technique to linearize the equation is to make the substitution y = v^(-1/n-1). The resulting equation is:

dv/dx + (P(x) + Q(x)/v^(1/n-1)) * (1/n-1) * v^(1/n-2) * dv/dx = 0.

For the initial value problem given, we have P(x) = -1/x, Q(x) = -5, and n = 2.

We make the substitution y = v^(-1), so v = y^(-1), and dv/dx = -y^(-2)dy/dx. The equation becomes:

-y^(-2)dy/dx + (-1/x - 5y^2) = 0.

We have the initial condition y(1) = 1/5. In terms of v, the initial condition becomes v(1) = 1/(1/5)^2 = 25.

Now, the differential equation is linear, and we can solve it using standard methods, such as separation of variables. To find the solution that satisfies the initial condition, we may use numerical methods such as the Euler method or Runge-Kutta method.

Elena receives $95 per year in simple interest from three investments totaling $2100 . Part is invested at 3%, part at 4%, and part at 5%. There is $1000 more invested at 5% than at 4%. Find the amount invested at each rate.

The amount invested at 3% is $
the amount invested at 4% is $
and the amount invested at 5% is $

Answers

The amount invested at 3% is $400, the amount invested at 4% is $700, and the amount invested at 5% is $1000.

Let's assume the amount invested at 4% is x dollars.

According to the given information, the amount invested at 5% is $1000 more than the amount invested at 4%.

So, the amount invested at 5% is (x + $1000).

The total amount invested is the sum of the amounts invested at each rate, which is $2100.

Therefore, we can write the equation:

x + (x + $1000) + (amount invested at 3%) = $2100

Now, we can calculate the amount invested at 3%.

We subtract the sum of the amounts invested at 4% and 5% from the total investment:

(amount invested at 3%) = $2100 - (x + x + $1000) = $2100 - (2x + $1000)

Given that Elena receives $95 per year in simple interest from the investments, we can use the formula for simple interest:

Simple Interest = Principal × Interest Rate

The interest earned from the investment at 3% is (amount invested at 3%) × 0.03, the interest earned from the investment at 4% is (amount invested at 4%) × 0.04, and the interest earned from the investment at 5% is (amount invested at 5%) × 0.05.

According to the problem, the total interest earned is $95.

So we can write the equation:

(amount invested at 3%) × 0.03 + (amount invested at 4%) × 0.04 + (amount invested at 5%) × 0.05 = $95

Now we can substitute the expression for (amount invested at 3%) and solve for x.

Once we have the value of x, we can calculate the amounts invested at 3%, 4%, and 5% using the given information.

Petra jogs 6 miles in 42 minutes. At this rate, how long would it take her to jog 8 miles?

Answers

To find out how long it would take Petra to jog 8 miles at the same rate, we can set up a proportion based on the distance and time relationship:

Distance 1 / Time 1 = Distance 2 / Time 2

Using the information given:
6 miles / 42 minutes = 8 miles / Time 2

To solve for Time 2, we can cross-multiply and then divide:

6 miles * Time 2 = 8 miles * 42 minutes

6 * Time 2 = 8 * 42

6 * Time 2 = 336

Now, we divide both sides by 6 to isolate Time 2:

Time 2 = 336 / 6

Time 2 = 56 minutes

Therefore, it would take Petra 56 minutes to jog 8 miles at the same rate.
