Answer:
40%
Step-by-step explanation:
1299-725= 574
574/1299 x 100 = 44.19%
Given that the measure of angle ADC = 90 degrees.
Notice that m<ADC = m<ADB + m<BDC
Let the measure of angle ADB be x degrees, then given that m<BDC is 34 degrees greater than m<ADB, thus, m<BDC = x + 34
Hence,
m<ADC = m<ADB + m<BDC
90 = x + x + 34 = 2x + 34
2x = 90 - 34 = 56
x = 28
Therefore, m<ADB = 28 degrees and m<BDC = 28 + 34 = 62 degrees.
Answer:
f(x) = 4^x
Step-by-step explanation:
In f(x) = (1/4)^x, 1/4 is equal to 0.25, which is less than 1, so its decreasing
In f(x) = 4^x, 4 is greater than 1, so its increasing
In f(x) = (0.4)^x, 0.4 is less than 1, so its decreasing
This is why f(x) = 4^x is the correct answer
I hope this helps!
