Mathematics
1 answer:
Luda [366]3 years ago

Answer:

Step-by-step explanation:

I really need help they never taught me this in my old school.
SIZIF [17.4K]
To find this, just plug the numbers into the expressions.

5x = y
5(2) = 7
10 = 7
So it can't be A.

x + 2 = y
2 + 2 = 7
4 = 7

x + 4 = y
2 + 4 = 7
6 = 7

2x + 3 = y
2(2) + 3 = 7
7 = 7

The correct answer is
D. 2x + 3

Why are 1 4 9 16 and 25 called perfect squares
olga nikolaevna [1]
Perfect squares can be divided and multiplied by the same number to get the same number. For example 25/5=5. 5*5=25.
4/2=2, 2*2=4
1/1=1, 1*1=1
9/3=3, 3*3=9
16/4=4, 4*4=16.
Hence the perfect squares.

In a unit circle, what is the length of an arc that subtends an angle of <br> π/4 radians?
olchik [2.2K]

A unit circle has radius 1, and thus circumference 2\pi.

Since an angle of \frac{\pi}{4} is one eighth of a whole turn, the length of an arc that subtends an angle of  \frac{\pi}{4} radians will be one eighth of the whole circumference:

l = \dfrac{2\pi}{8} = \frac{\pi}{4}

In fact, the radians have the property that, in the unit circle, the length of the arc is exactly the measure of the angle. In general, you have

l = r\cdot\alpha

where l is the length of the arc, r is the radius and \alpha is the angle in radians. So, if r=1, you have l=\alpha
