Find sin A. 12/13<br> B. 1<br> C. 13/12<br> D. 13/5
vladimir1956 [14]

Answer: A. \frac{12}{13}

Step-by-step explanation:

The best way to remember this is SOH-CAH-TOA. For sin, it would be the opposite angle over the hypotenuse. The opposite angle of ∠C is 24 and the hypotenuse is 26. But that isn't in the answer choices, so you'll simplify the fraction.

\frac{24}{26} =\frac{12}{13}, therefore, the answer is A.

I hope this helps! Pls mark brainliest!! :)

A number y is rounded to 2 decimal places
Yakvenalex [24]
Y can be rounded up to 1.51 from a minimum value of 1.505
This is the lower bound.

y can be rounded down to 1.51 from a maximum value of 1.515
this is the upper bound.

y is between the lower bound and the upper bound so y is between 1.505 and 1.515

This is shown as 1.595<=y<1.515

<= is the typed out version of (greater than/equal to) which is < with a line under it.

Which is the graph of f(x) = Square root of x?
natka813 [3]

Answer:

Third option given

Step-by-step explanation:

On a coordinate plane, a parabola opens to the right with a vertex at (0, 0).

use the following x values to plot the associated y values on the x-y plane:

If x = 0,  then y=\sqrt{0}  =0

If x = 1,  then y=\sqrt{1}  =1

If x = 4,  then y=\sqrt{4}  =2

If x = 9,  then y=\sqrt{9}  =3

Join the points and you will find a branch of a parabola opening to the right.
