Answer:
x=7
Step-by-step explanation:
The triangle is right angled meaning that one of the angles is 90⁰.
90+30+(9x-3)=180 (Angle sum property of a triangle)
120+9x-3=180
9x-3=180-120
9x-3=60
9x=60+3
x=63/9
<em><u>x=7</u></em>
The angle will be (9×7)-3=<u>60⁰</u>
Answer: f(x) = 3(0.7)^x
Because as the exponent (x) of 0.7 grows the result decreases. When x is a big negative number the decay is fast, when the x is a big positive number the decay is low, and the function appraches assymptotically to a constant value. This is the behavior of an exponentially decaying function.
Answer:
There is a common ratio of 1/4.
The next 3 numbers are -80, -20 , -5.
Step-by-step explanation:
The next term is found by multiplying by 1/4. ( -5120 / 20480 = 1/4).
So the next 3 terms are -320 * 1/4 = -80,
-80 * 1/4 = -20 and the last is -5.
