The formula to find the amount of interest earned is I = PRT.
What is given?
Principal = $18000
Rate = .08 ( I assume you confused rate and si)
Time = .3671 in years (convert days into years) by dividing total days by 365.
I = ?

I = 18000(.08)(.3671)
I = $528.62

Pls help meeeee I only have 5 mins left use the graph from number 3 to anwser number 4
Mariana [72]

Answer:

Option C

Step-by-step explanation:

From the graph attached,

Slope of the line passing through two points A and B will be,

m = \frac{\text{Rise}}{\text{Run}}

   = \frac{12}{8}

   = \frac{3}{2}

Triangles having same ratio of Height and base (slope) will lie on the line graphed.

Option A

Slope pf the triangle  = \frac{44}{21}

\frac{3}{2}\neq \frac{44}{21}

Slope of the line ≠ Slope of the triangle

Therefore, triangle will not lie on the line.

Option B

Slope of the triangle = \frac{36}{12}=\frac{3}{1}

\frac{3}{2}\neq  \frac{3}{1}

Triangle will not lie on the line.

Option C

Slope of the triangle = \frac{30}{20}= \frac{3}{2}

Since, slope of the line = slope of the triangle

\frac{3}{2}= \frac{3}{2}

Triangle will lie on the line.

Option D

Slope of the triangle = \frac{52}{26}=\frac{2}{1}

But \frac{3}{2}\neq \frac{2}{1}

Therefore, triangle will not lie on the given line.

What is the measure of angle x? Round to the<br> nearest tenth. .<br> 28<br> 21<br> xº
attashe74 [19]

Answer:

x =53.1

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side/ adjacent side

tan x = 28 /21

Take the inverse tan of each side

tan ^-1 (tan x) = tan ^-1 (28/21)

x = 53.13010235

Rounding to the nearest tenth

x =53.1

Consider circle Y with radius 3 m and central angle XYZ measuring 70°.
Fofino [41]

Answer:

3.7

Step-by-step explanation:

We have been given an image of the circle Y. We are asked to find the length of minor arc XZ.

We will use arc length formula to solve for our given problem.

\text{Arc length}=\frac{\theta}{180}\times \pi r, where,

\theta=\text{Measure of central angle},

r=\text{Radius of circle}.

Upon substituting our given values in the above formula we will get,

\text{Arc length}=\frac{70}{180}\times \pi*3

\text{Arc length}=\frac{7}{6}\times \pi

\text{Arc length}=3.66519\approx 3.7

Therefore, the length of minor arc XZ is 3.7.
