if you are allowed to use calculators, then do so, if not, you're going to have to do a lot of division
Answer:
Domain: all real numbers. Range: (-∞, 2000]
Step-by-step explanation:
f(x)=2.5x is a simple "ramp" function, a linear function and a polynomial. As such, its domain contains "all real numbers." That value 800 defines the largest value that this f(x) can have: f(800) = 2.5(800) = 2000.
Thus, the range is "all real numbers from -∞ through and including 2000."
Answer:
Given:
Area of circle = 616 cm²
To Find:
Radius of circle
Step-by-step explanation:
Answer:
The correct answer is first option m<2 + m<3
Step-by-step explanation:
From the figure we can see a triangle with angles, <1, <2 and <3
By angle sum property we can write,
m<1 + m< 2 + m<3 = 180°
m<1 = 180 - (m<2 + m<3) ----(1)
Also we know that, <1 and <4 are linear pairs
m<1 + m<4 = 180°
m<1 = 180 - m<4 ---(2)
Compare (1) and (2) we get
m<4 = m<2 + m<3
Sin is the measure of the opposite leg over the hypotenuse from the given angle:
opposite/hypotenuse
We must find the sin of Angle A, and in order to do so we must find the opposite leg and hypotenuse:
opposite leg/hypotenuse
8/10
Simplify:
8/10 = 4/5
Hence, the sin of <A is 4/5
