______________
Answer:
225 miles
Step-by-step explanation:
45 miles in 30 mins

sin(A+B) - sin(A-B) = 2cos A sin B
Prove that answer please , I'm stuck
Answer:
Step-by-step explanation:
Hello,
I assume that you know that
[tex]sin(A+B)=sinAcosB+cosAsinB\\\\sin(A-B)=sinAcosB-cosAsinB[/tex]
One way to retrieve them quickly is to use Euler's formula and then,
[tex]cos(A+B)+isin(A+B)=e^{i(A+B)}=e^{iA}e^{iB}=(cosA+isinA)(cosB+isinB)[/tex]
and you can replace B by -B for the second formula.
So, it comes that sin(A+B)-sin(A-B)=2cosAsinB

Woul I use open or close intervals for x - 1 < 5
Hi there!
You would use open intervals.
In the given inequality, the "<" sign is used, which means "greater than".
Open intervals would be used unless the inequality uses "≤" or "≥", which
mean "equal to or greater/less than". Closed brackets would be used in this
instance.

The total number of players on team A 24 is and on the team, B is 20.
What is a quantitative relation?The comparison of two quantities of constant units illustrates the quantitative relationship by showing what percentage of one quantity is a gift inside the other.
Team A's total player count should be "x" and Team B's total player count should be "y.".
Assuming that 3 players on Team A (or 1/8 of the players) have scored goals, this can be represented by,
1/8(x) = 3
x = 3 × 8
x = 24
Given that 4 players on Team B have scored goals, 1/5 of the players have scored a goal, which can be represented by,
1/5(y) = 4
y = 4 × 5
y = 20

Mrs. Cook is a teacher whose salary is $23,125 for a 185-day school year. In Mrs. Cook's school district, substitute teachers are paid at a rate of $90 per day. If a substitute is paid to teach Mrs. Cook's class in her absence one day, how much less does the school district pay in salary by paying a substitute teacher instead of paying Mrs. Cook for that day? *
Answer:
35
Step-by-step explanation:
23,125/185= 125
125-90 = 35
$35 less amount school district pay in salary by paying a substitute teacher instead of paying Mrs. Cook for that day
What is unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mrs. Cook is a teacher whose salary is $23,125 for a 185-day school year.
Mrs. Cook per day salary= 23125/ 185 = $125
Now, substitute teachers are paid at a rate of $90 per day.
So, if substitute teachers take class instead of Mrs. Cook, then school will pay
= 125-90
=$35 less amount.

Function h is a transformation of the parent exponential function. Which statement is true about this function? h(x) = 2^(x-5)
As x approaches negative infinity, h(r) approaches negative infinity.
As x approaches positive infinity, h(t) approaches 0.
As x approaches positive Infinity, h(t) approaches positive infinity.
As x approaches negative infinity, h(a) approaches positive infinity.
Answer: As x approaches positive infinity, h(x) approaches positive infinity
Step-by-step explanation:
The correct option is Option C: As x approaches positive Infinity, h(t) approaches positive infinity.
What is the exponential function?The exponential function is a function where the base is raised exponent times where the exponent is an input variable and the base is a constant.
For example: f(x)= aˣ
Similarly here given in the question,
the function is h(x)= [tex]2^{x-5[/tex]
the domain of this function is real number R i.e (-∞,∞)
The range of the function is real numbers greater than 0.
So when x approaches to negative infinity,
[tex]\lim_{x \to- \infty} h(x)[/tex]
= [tex]\lim_{x \to- \infty} 2^{x-5[/tex]
= 2^(-∞-5)
= 2^(-∞)
= 1/2^∞
=0
So, As x approaches negative infinity, function h(x) approaches 0.
Then when x approaches to positive infinity,
[tex]\lim_{x \to \infty} h(x)[/tex]
= [tex]\lim_{x \to \infty} 2^{x-5[/tex]
= 2^(∞-5)
= 2^(∞)
= ∞
So, As x approaches positive Infinity, h(t) approaches positive infinity.
By checking all the options there is only one option that matches the above conclusion.
Therefore the correct option is Option C: As x approaches positive Infinity, h(t) approaches positive infinity.

You work at a video game store. Today, you are offering coupons for $10.00 off any new video game. A customer comes in with a coupon and purchases one video game for $59.99 and one controller for $39.99. How much should you charger this customer before tax?
Answer:
[tex]\huge\boxed{\$ 88.98}[/tex]
Step-by-step explanation:
In order to find the total price, we know that the total price will be all the items added up minus the coupon.
You get 10$ off any new video game. This means that when the customer purchases a video game for $59.99, he earns $10 off, so it ends up costing [tex]59.99-10=\$49.99[/tex].
Now we can add 39.99 to this since we do nothing to it. [tex]49.99+39.99=88.98[/tex]

1. Amazon is experimenting with "drone delivery" and you are asked to determine a drone’s delivery route. The drone will leave the Amazon warehouse, make two deliveries, and then return to the warehouse. The first delivery is 7.10 miles from the warehouse in a direction 25.0O south of west. The second delivery is 11.2 miles, in a direction 38.0O south of east, from the location of the first delivery. After making its second delivery, how far and in what direction must the drone fly to return to the warehouse?
Answer:
Step-by-step explanation:
From the information given:
Let assume that the drone first delivery went to a certain place U, 7.10miles from the warehouse in the S 25.0° W direction.
However, the drone thus proceeds to the second delivery place V which is 11.2 miles in the S 38.0° W direction.
Then, location U can be determined from a graphical point of view as follows:
In the negative x-direction from the warehouse
[tex]U_x = 7.1 \times cos 25^0[/tex]
[tex]U_x = 7.1 \times 0.9063[/tex]
[tex]U_x = 6.44 \ miles[/tex]
In the negative y-direction from the warehouse
[tex]U_y =7.1 \times sin 25 ^0[/tex]
[tex]U_y =7.1 \times 0.4226[/tex]
[tex]U_y = 3.00 \ miles[/tex]
Also: the position of V with respect to U can be determined as follows:
in the positive x-direction from the warehouse
[tex]V_{UX} = UV \ cos 38[/tex]
[tex]V_{UX} = 8.83 \ miles[/tex]
In the negative y-direction from the warehouse:
[tex]V_{UY} = UV \ sin 38[/tex]
[tex]V_{UY} = 6.89 \ miles[/tex]
Similarly, we will need to determine the position of V with respect to the warehouse.
i.e.
In the positive x-direction the warehouse
[tex]V_x = U_x +V_{UX}[/tex]
[tex]V_x =[/tex] -6.44 + 8.83 ( since [tex]U_X[/tex] is in the negative direction)
[tex]V_x =[/tex] 2.39 miles
In the positive y-direction the warehouse
[tex]V_Y = U_Y + V_{UY}[/tex]
[tex]V_Y = -3.00 + (-6.89)[/tex] ( since both [tex]U_Y \ and \ V_{AY}[/tex] are in the negative direction)
[tex]V_Y =[/tex] -9.89 miles
Therefore, from above, the distance emanating how far is the drone back to the starting point is :
[tex]D = \sqrt{V_X^2+V^2_Y}[/tex]
[tex]D = \sqrt{(2.39)^2+(-9.89)^2}[/tex]
[tex]D = \sqrt{5.7121+97.8121}[/tex]
D = 10.18 miles
The direction of the drone can be deduced by taking the tangent of the trigonometry;
i.e.
[tex]tan \ \theta = ${\dfrac{opposite \ direction}{adjacent \ direction}}[/tex]
[tex]tan \ \theta = ${\dfrac{9.89}{ 2.39}}[/tex]
[tex]tan \ \theta =4.138[/tex]
[tex]\theta = \tan^{-1}(4.138)[/tex]
[tex]\theta = 76.41^0[/tex] in the north_west direction of V
simplify each expression into a single number using standard algorithms.

The GCF of x^9, x^8, and x^6 is x^6.
The GCF of the terms of the polynomial is 5x^6.
Now we factor it out of the polynomial by dividing each term of the polynomial by the GCF of the polynomial.
