Answer:
Step-by-step explanation:
- log 2x + log (x - 5) = 2
- log (2x(x - 5)) = 2
- 2x(x - 5) = 10²
- 2(x² - 5x) = 100
- x² - 5x - 50 = 0
- x² + 5x - 10x - 50 = 0
- x(x + 5) - 10(x + 5) = 0
- (x - 10)(x + 5) = 0
- x = 10
- x = -5, this root is discounted as log should be positive.
Correct choice is 3.
96/4=24 so the length of a standerd paralleegram is 24
Answer:
∠A = 26°
Step-by-step explanation:
Supplementary angles total 180°.
∠A +∠B = 180°
(x -16)° +(3x +28)° = 180°
4x° + 12° = 180°
x° +3° = 45°
x° = 42°
∠A = (x -16)° = 42° -16°
∠A = 26°
Answer:
3
Step-by-step explanation:
f(x)=a*b^x - is a formula of exponential function
As we know the point (x=0; y=3) lies at the function's graph.
So we have to put in formula f(x)=a*b^x x=0 f(x)=y=3
3=a*b^0 (b^0=1) => 3=a*1 => 3=a
Idk but just divide both of the fraction hope i helped you a little
