[tex]\checkmark[/tex] [tex]\sin\theta=-\frac{\sqrt{2}}{2}[/tex]
[tex]\checkmark[/tex] [tex]\tan \theta = -1[/tex]
[tex]\checkmark[/tex] The measure of the reference angle is [tex]45^{\circ}[/tex]
Step-by-step explanation:
The reference angle of an angle is the magnitude of the smallest angle it makes with the x-axis. In this case, we have [tex]360-315=\boxed{45^{\circ}}[/tex] (*Note: [tex]\frac{7\pi}{4}=315^{\circ}[/tex], use [tex]\pi=180^{\circ}[/tex] to convert to degrees)
Step-by-step explanation:
Convert 7π/4 to degrees
You'll have 315°
Reference angle is the angle that a given angle makes with the abscissa or x-axis.
360-315 = 45°
THE MEASURE OF THE REFERENCE ANGLE IS 45°
C and D are correct also

The second one is 2:8, or 1:4. I am not sure if they want you to actually count each banana, but if so, that would be the answer. For every 2 apples, there are 8 bananas. If you are not supposed to count the bananas, it would be 2:2, or 1:1.

The mean distance that and Tina drove was 153 kilometers.If Ben drove 24 kilometers more than Tina,what was the distance that Tani drove?
Answers
Answer:
141 km
Step-by-step explanation:
Given data
Mean distance= 153km
Let Tina dirve=x km
Ben= x+ 24
Number of participants= 2
Hence,
Mean= total distance/number of participants
153= x+24+x/2
cross multiply
153*2= x+24+x
306 =2x+24
306-24= 2x
282=2x
Divide both sides by 2
x= 282/2
x= 141km
Hence Tina drove 141 km

Sixty-three is 60% of..
Answers
Answer:
63 is 60% of 105.
Step-by-step explanation:
Divide 63 by 3 to get 21. Now that you get 1/3 of that number, it would also mean that 21 is 20% of the full number. Multiply 21 by 5 to get the full number which is 105.
Answer:
105
Step-by-step explanation:
63 = 60% x ?
60/100 x ? = 63
100/60 x 60/100 = 1 (you do this to cancel it out)
60/100 x 63 = 105
A cone has a slant height of 8 cm and a radius of 2 cm. Estimate the surface area using π =3, and then calculate a more accurate surface area using π =3.14.
Answers
9514 1404 393
Answer:
initial estimate: 60 cm²better estimate: 62.8 cm²Step-by-step explanation:
The total surface area of a cone with radius r and slant height s is ...
A = πr² +πrs = πr(r +s)
For the given dimensions and π≈3, the area is approximately ...
3(2 cm)(2 cm +8 cm) = 60 cm²
For π≈3.14, the area is approximately ...
(20cm²)(3.14) = 62.8 cm²
Which statement identifies and explains Limit of f (x) as x approaches 0?
Answers
Third option, counting from the top.
Remember that we say that a limit exists, like:
[tex]\lim_{x \to 0} f(x) = a[/tex]
if and only if:
[tex]\lim_{x \to 0_-} f(x) = a[/tex]
and
[tex]\lim_{x \to 0_+} f(x) = a[/tex]
Where the above two limits say that when we approach zero from the negative side (the first one) and from the positive side (the second one), we must get the same value.
Also, remember that the limit is an approximation through near points
Then, regardless the fact that f(0) = -2, we can see that as x approaches 0 from both sides, the value of the function approaches 4.
Thus, we can conclude that the limit of f(x) when x tends to zero is equal to 4.
The correct option is the third one.

You choose a red card from a deck of 52 cards and keep it. Then you choose another red card.
A boy rolls a 5 on a six-sided die. The boy rolls the die again and gets another 5.
Answers
The correct answer would be option (A) because the family would be dependent.
What are dependent Events?A dependent Event is defined as if the outcome of one event has bearing on the outcome of the other, the two events are said to be dependent events. Or, we may say that an event is considered dependent if it does affect the probability of another event. Probability-dependent is dependent on occurrence.
What is probability?The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
According to option (A),
The first child in a family is a boy. The second child is also a boy.
A boy is the family's youngest. Another boy is the second child.
Here the family would be the dependent.
Hence, the correct answer would be an option (A).

We need to express in scientific notation.
A number can be written in scientific notation as follows :
[tex]N=a\times 10^b[/tex]
Where
a is a real number and b is an integer
[tex]5,890,000=5.89\times 10^6[/tex]

Answer:
5/8 (= 0.625)
Step-by-step explanation:
tan A = sin A / cos A
we have here a triangle that is much bigger than to fit into our snuggly around a norm circle (radius = 1).
so, we could either see it embedded in a circle with a radius of the square root of 89, or surrounding a circle with the radius of 8.
in the first case
[tex]5 = \sin(a) \times \sqrt{89} [/tex]
[tex]8 = \cos(b) \times \sqrt{89} [/tex]
in the second case 5 is already tan A but stretched by the radius 8.
so,
[tex]5 = \tan(a) \times 8[/tex]
so, in both cases the answer is 5/8.
