1: answer: 4^6 ( reduce the fraction with 4^3)

2: answer: 1 ( any nonzero expression raised to the power of 0 equals 1 )

3: answer 3^8
steps: (3^2)^4 = 3^2×4 ( to raise a power to another Power multiply the exponents)
3^2×4 = 3^8 ( multiply the 2 and the 4 exponent to get a 8 as a exponent )

Write an exponential function whose graph passes through the given points (0, - 2) and (- 1, - 4)

melamori03 [73]

Answer:

$y = 2(0.5) {}^{x}$

Step-by-step explanation:

Use the general formula of exponential equation

$y = ab {}^{x}$

Plug 0,2 into the function

$- 2 = ab {}^{0}$

$- 2 = a \times 1$

$a = - 2$

$y = - 2b {}^{x}$

$- 4 = - 2b {}^{ - 1}$

$2 = b {}^{ - 1}$

${2}^{ \frac{ 1}{ - 1} }$

$2 {}^{ - 1} = 0.5$

B=0.5

$y = 2(0.5) {}^{x}$

the diagram below shows the angles formed by some intersecting lines. give that m<8=34, m<9=40, and mm<3=62, find the m

MrMuchimi

Answer:

m<4 = 44°

Step-by-step explanation:

m<8 = 34°

m<9 = 40°

m<3 = 62°

m<2 = 34° + 40° (exterior angle theorem of a triangle)

m<2 = 74°

m<3 + m<4 + m<2 = 180° (sum of ∆)

62° + m<4 + 74° = 180° (substitution)

m<4 + 136° = 180°

m<4 = 180 - 136 (substitution property of equality)

m<4 = 44°
