Which Triangle Is A 30-60-90 Triangle?10ch55/31555310O 510./315105/3

Answers

Answer 1

Answer:

the first one

Step-by-step explanation:

Hey There!

Look at the image for the rule of a 30- 60 - 90 triangle

x = 5

the hypotenuse would be x2 so 10

the longer leg would be x[tex]\sqrt{3}[/tex]

So the first triangle is the right answer

Answer 2

The first triangle in the figure is a 30°-60°-90° triangle.

What is a triangle?

A triangle is a polygon with three sides and three angles.

Given are triangles, we need to see which of them are a 30°-60°-90° triangle,

So,

In a 30°60°-90° triangle, the side opposite the 30° angle (shortest side) is half the length of the hypotenuse.

So you have to choose one with 5 & 10.

Use the Pythagorean theorem to calculate the remaining side

a² + b² = c²

5² + b² = 10²,   so b² = 100-25  √b²=√75  so √(25)(3)  

b= 5√3

Hence, the first triangle in the figure is a 30°-60°-90° triangle.

G (x ), represents transformations on the parent function of y = (½) x Write the equation for g (x ).

Answers

Complete Question:

g(x), represents transformations on the parent function of [tex]y = (\frac{1}{2})^x[/tex].

Write the equation for g (x ) with the following transformations:

Reflect over y-axis, and shift right 7

Answer:

[tex]g(x) = (\frac{1}{2})^{-x-7}[/tex]

Step-by-step explanation:

Given

[tex]y = (\frac{1}{2})^x[/tex]

Represent the function as:

[tex]f(x) = (\frac{1}{2})^x[/tex]

Taking the transformations, one after the other:

Reflect over the y-axis.

This is represented by the rule: (x,y) ==> (-x,y)

So, we have:

[tex]f'(x) = (\frac{1}{2})^{-x}[/tex]

Shift right 7 units

This is represented by (x,y) = (x - b, y)

Where b represents the number of units

So, we have:

[tex]f'(x-7) = (\frac{1}{2})^{-x-7}[/tex]

Hence:

[tex]g(x) = (\frac{1}{2})^{-x-7}[/tex]

Solve for x in the diagram below.

Answers

Answer:

x = 20°

Step-by-step explanation:

here's your solution

=> it is given that whole angle is 90°

=> so, x + (3x + 10) = 90°

=> x + 3x + 10 = 90°

=> 4x + 10 = 90°

=>4x = 90 - 10

=> 4x = 80°

=.

=> x = 80/4

=> x = 20°

one angle is 20° and other 70°

hope it helps

Answer:

20 is your answer

x+3x+10=90 being right angle

4x=90-10

Daniela fue a la florería a comprar rosas rojas para regalar a su madre el día de su cumpleaños. Si una rosa cuesta $2.550 ¿Cuánto cuesta 2 docenas?

Answers

Answer:

2 docenas cuestan $61.200.

Step-by-step explanation:

Para encontrar la respuesta, debes considerar que una docena equivale a 12 artículos, por lo cual tienes que multiplicar 12 por 2 para encontrar el número de rosas en 2 docenas:

12*2=24

Ahora, dado que sabes que una rosa cuesta $2.550 tienes que multiplicar este valor por 24 para encontrar cuanto cuestan 2 docenas:

$2.550*24=$61.200

De acuerdo a esto, la respuesta es que 2 docenas cuestan $61.200.

A university will add fruit juice vending machines to its classroom buildings if the student body president is convinced that more than 20 percent of the students will use them. A random sample of n students will be selected and asked whether or not they would use the vending machines. A large-sample test for proportions at the significance level of a = 0.05 will be performed. The null hypothesis that the proportion of all students who would use the vending machines is 20 percent will be tested against the alternative that more than 20 percent of all students would use them. For which of the following situations would the power of the test be highest?
A .The sample size is n = 750, and 20 percent of all students actually use the vending machines.
B. The sample size is n = 750, and 50 percent of all students actually use the vending machines.
C. The sample size is n = 1,000, and 55 percent of all students actually use the vending machines.
D. The sample size is n = 1,000, and 25 percent of all students actually use the vending machines.
E. The sample size is n = 500, and 50 percent of all students actually use the vending machines.

Answers

Answer:

The power of the test will be highest for;

C. The sample size is n = 1,000, and 55 percent of all students actually use vending machines

Step-by-step explanation:

For a large sample test for proportions, we have;

[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p \cdot q}{n}}}[/tex]

Where;

[tex]\hat p[/tex] = The percentage of the hypothesized proportion = 20% = 0.20

p = The actual proportion

n = The size of the sample

The power of the test increases when;

The sample size 'n' is large

When the true vale of the measured items in the test is much larger than the value set as the null hypothesis

When the significant level is high

Therefore, we have;

The power of the test will be highest when the sample size is n = 1,000, and 55 percent of all students actually use vending machines

then:

-6/5x - 7 = 2/5x + 1

simplify:

-8/5x = 8

divide both sides by 8:

-1/5x = 1

multiply both sides by 5:

-x = 5

x = -5

Please help me will give brainlyest Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed.
