suppose a triangle has sides a,b, and c, and that a²+b²>c². Let theta be the measure of the angle opposite the side of length of C
Answer:
The triangle is not a right triangle
[tex](\theta)[/tex] is an acute angle
[tex]cos(\theta) > 0[/tex]
Step-by-step explanation:
we know that
If a²+b²>c²
then
Is an acute triangle
therefore
angle theta must be less than 90 degrees
Hence
The triangle is not a right triangle
[tex]cos(\theta) > 0[/tex]
[tex](\theta)[/tex] ---> is an acute angle
Answer choices
F(x) or G(x)
for both A and B
Answer:
A. f(x)
B. g(x)
Step-by-step explanation:
The initial amount if the value of the function at x = 0.
Here that value is 2000 for the f(x) and 1000 for the g(x), so the f(x) has the higher initial value.
For the second part, by looking at the graph, you can determine that the function for the g(x) is 1000(3)^x (because the g(1) is 3000). Plugging in two for both the function, you get the f(x) = 8,000 and the g(x) = 9,000, so the g(x) has the greater amount of bacteria after two days.

The answer is 74 square units so B
Hope this helps you
Have a great day
☆ Dont forget to mark brainliest ☆
Answer:
EBCD=55.5 square units
Step-by-step explanation:
Since EBCD is a trapezoid you would plug in the lengths of the sides into the formula. First I will give you the side lengths.
BC=√37
EB=√37
CD=√74
ED=2√37
To solve for the area of EBCD we have to plug the numbers into the trapezoid formula 2√37+√37 divided by 2 times √37 =111/2 which that equals 55.5 square units.

A fast food restaurant sells burgers, chicken sandwiches, and entree salads. If a customer buys a burger, the probability they buy french fries is 0.80. Fifty percent of customers who purchase a chicken sandwich also buy fries, but only 10% of those buying an entree salad buy fries. Of all customers, 65% buy a burger, 20% a chicken sandwich, the rest buy an entree salad.
What proportion of customers get a burger and fries?
Answer:
52%
Step-by-step explanation:
We are told that, of all customers 65% buy a burger. This would imply that the proportion of customers who buy a burger is 0.65.
Moreover, if a customer buys a burger, the probability they buy french fries is 0.80. This implies that the proportion of customers who buy fries given that they bought a burger is 0.8.
Therefore, the proportion of customers who get a burger and fries is simply the product of the two probabilities;
= 0.65*0.8
= 0.52
Therefore, 52% of all customers get a burger and fries
An airplane is at a location 800 miles due west of city X. Another airplane is at a distance of 1,200 miles southwest of city X. The angle at city X created by the paths of the two planes moving away from city X measures 60°. What is the distance between the two airplanes to the nearest mile? Assume that the planes are flying at the same altitude.
Answer:
The distance between the two airplanes (to the nearest mile) is 1058 miles.
Step-by-step explanation:
An airplane A is at a location 800 miles due west of city X. So AX = 800 miles.
Another airplane is at a distance of 1,200 miles southwest of city X. So BX = 1200 miles.
The angle at city X created by the paths of the two planes moving away from city X measures 60°. So angle ∠AXB = 60°.
In triangle ΔAXB, AX = 800 miles, BX = 1200 miles, ∠AXB = 60°.
Using law of cosines:-
AB² = AX² + BX² - 2 * AX * BX * cos(∠AXB).
AB² = 800² + 1200² - 2 * 800 * 1200 * cos(60°).
AB² = 640000 + 1440000 - 2 * 960000 * 1/2
AB² = 2080000 - 960000
AB² = 1120000
AB = √(1120000) = 1058.300524
Hence, the distance between the two airplanes (to the nearest mile) is 1058 miles.

The two triangular pyramids are similar. The smaller pyramid has a volume of 52 inches3. What is the volume of the larger pyramid? Round to the nearest tenth. in.3
Answer:
the volume of the larger pyramid = 175.5 inches³
Step-by-step explanation:
* Lets revise the similar
- If two solids are similar,then the ratio between each two
corresponding dimensions are qual
- Their perimeters have the same ratio
- Their areas have the square of the equal ratio
- Their volumes have the cube of the equal ratio
* Lets solve the problem
- The two triangular pyramids are similar
- The perimeter of the base of the small one = 14 inches
- The perimeter of the base of the big one = 21 inches
∴ The ratio of the similarity = 14/21 = 2/3
∴ The ratio between their volumes is (2/3)³ = 8/27
∵ The volume of the small one = 52 inches³
- W will us the cub of the ratio to find the larger volume
∴ 52/V = 8/27 ⇒ by using the cross multiplication
∴ 52 × 27 = 8 × V
∴ 1404 = 8V ⇒ divide both sides by 8
∴ V = 175.5 inches³

In a lottery game, a player picks six numbers from 1 to 20. If the player matches all six numbers, they win 30,000 dollars. Otherwise, they lose $1.
What is the expected value of this game?
The expected value of the lottery game is -$0.62, suggesting a long-term average loss of 62 cents per game played. This value is calculated by considering the probability of each outcome and the associated gain or loss.
Explanation:In order to calculate the expected value of the lottery game, we must first understand what expected value truly represents. The expected value is essentially a description of the average outcome of a series of events if these events are repeated many times. It's a statistical concept used to predict the long-range behavior of random events, such as lottery games.
The expected value is calculated as the sum of all possible values each multiplied by the probability of its occurrence. For the lottery game described, there are two possible outcomes: a win of $30,000 or a loss of $1.
The probability of winning is extremely low. In this game, the player is attempting to choose the correct 6 numbers out of 20, which is a 1 in 38,760 chance. Whereas, the probability of losing is extremely high, practically 38,759 out of 38,760.
Thus, the Expected Value (E) can be calculated as follows: (probability of winning x winnings) + (probability of losing x loss). Plugging in our values gives us an expected value of -$0.62, rounded to the nearest cent. This figure indicates that if one were to play this game repeatedly, their average loss per game would be about 62 cents.

What is the value of f^-1 (2)
Answer:
2/f is the correct answer.
The value of f^-1(2) refers to the value of x in the original function f(x) that corresponds to f(x) = 2. Essentially, it is asking what value of x, when substituted into the original function, would provide an answer of 2.
Explanation:The value of f^-1(2) is the pre-image, or the value of the variable x in the original function f(x), that corresponds to f(x) = 2 in the original function. An inverse function undoes the operation of the original function. For instance, if you have a function f(x) = y, the inverse function, denoted f^-1, would give you back x when you input y. Therefore, f^-1(2) asks for the value of x that would result in f(x) = 2 in the original function.

A. 50%
B. 84%
C. 13.5%
D. 16%
Answer:
B. 84%
Step-by-step explanation:
Given
Mean= π=75
Standard Deviation= σ=5
As we have to calculate the percentage of score less than 80, we will find the z-score of 80
z=(x-μ)/σ
= (80-75)/5
=5/5
=1
The z-score table value for 1 is 0.8413.
For converting this value into percentage, the value will be multiplied by 100.
So,
Percentage of students whose score is less than 80 = 0.8413*100

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:
Per click charges= 80 cents
Total clicks= 3320
