Answer:

Step-by-step explanation:

Question 1:  Assumption: This is a 30-60-90 triangle.

Remember that the sides of a 30-60-90 triangle are in the ratio 1:√3:2

The side opposite the 90° angle is 16, so the side opposite the 30° angle is 16/2 =  8

x = 8 units.

:::::

Question 2:  Assumption: This is an isosceles triangle.

Draw the altitude to the vertex angle and you get a 30-60-90 triangle.

The side opposite the 90° angle has length 22, so the side opposite the 30° angle has length 11.

x/2 = 11

x = 22 units

:::::

Question 3:  Assumption: This is a 45-45-90 triangle.

The sides of a 45-45-90 triangle are in the ratio 1:1:√2

The sides opposite the 45° angles are 19 and x.

x = 19

:::::

Question 4:  Assumption: This is an isosceles triangle.

x = 13 units

:::::

Question 5:  Assumption: This is a right triangle.

sin(54°) = x/45

x = 45sin(54°) ≅ 36.4 units

:::::

Question 6:  Assumption: This is a right triangle.

sin(35°) = z/23

z = 23sin(35°) ≅ 13.2 units

Find the linear approximation of the function g(x) = 5 1 + x at a = 0. g(x) ≈ use it to approximate the numbers 5 0.95 and 5 1.1
34kurt

Differentiating the function

... g(x) = 5^(1+x)

we get

... g'(x) = ln(5)·5^(1+x)

Then the linear approximation near x=0 is

... y = g'(0)(x - 0) + g(0)

... y = 5·ln(5)·x + 5

With numbers filled in, this is

... y ≈ 8.047x + 5 . . . . . linear approximation to g(x)

Using this to find approximate values for 5^0.95 and 5^1.1, we can fill in x=-0.05 and x=0.1 to get

... 5^0.95 ≈ 8.047·(-0.05) +5 ≈ 4.598 . . . . approximation to 5^0.95

... 5^1.1 ≈ 8.047·0.1 +5 ≈ 5.805 . . . . approximation to 5^1.1

Part A: If (2^6)^x = 1, what is the value of x? Explain your answer. (5 points)
vladimir1956 [14]

Answer:

0,1,-1

Step-by-step explanation:

A.

(2^6)^x=1\\(2)^{6x}=1=2^0\\6x=0\\x=\frac{0}{6}=0

B

(5^0)^x=1\\5^0=1\\1^x=1\\x=0,1,-1\\1^0=1\\1^1=1\\1^{-1}=\frac{1}{1^1}=\frac{1}{1}=1
