-this situation can be represented by the exponential function f(x)=60*1.15x
-this function has no x intercept
-after 4 years, the value of the investment will be $120
-after 6 years, the value of the investment will be $653
-after 7.86 years the value of the investment will be 3 times the initial value
-after 8 years, the value of the investment will be $184

15% each yer
represented by
f(x)=60(1.15^x)

xintercept is when the function equals zero
since it increases only, it cannot equal zero and does not have an x intercept

after 4 years the investment value is 104
after 6 yaers value is 138.7
after 7.86 years the value is179.98 which is roughly 3 times of 60
8 years later183.54 close enough










answers
f(x)=60*1.15^x
after 7.86 years value is 3 times initioal value
after 8 years value is 184

The length of segment XY is 9 cm. Which statements regarding triangle XYZ are correct? Check all that apply.
Dominik [7]

<u>Answer-</u>

  • YZ = 9 cm
  • XZ=9\sqrt2
  • XZ is the longest segment in triangle XYZ.

<u>Solution-</u>

Triangle XYZ is a right angle triangle with ∠Y=90°

Triangle XYZ is also an isosceles triangle, as

∠X =45°= ∠Z

Therefore, triangle XYZ is a right angle isosceles triangle.

So,

XY = YZ = 9 cm

Applying Pythagoras theorem,

\Rightarrow XZ^2=XY^2+YZ^2\\\\\Rightarrow XZ^2=9^2+9^2\\\\\Rightarrow XZ^2=2\times 9^2\\\\\Rightarrow XZ=\sqrt{2\times 9^2}=9\sqrt2

In a right angle triangle, always the hypotenuse is the largest. So XZ is the longest segment in triangle XYZ.

Write the equation of a line that is parallel to y = 1/2 x + 5
kumpel [21]

Answer:

y = 1/2x + 5

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

When 2 lines are parallel, they have the same slope.

Step 1: Define variables

Random point (2, 6)

<em>m</em> = 1/2

y = 1/2x + b

Step 2: Find <em>b</em>

6 = 1/2(2) + b

6 = 1 + b

5 = b

Step 3: Rewrite parallel linear equation

y = 1/2x + 5
