Answer:
B. $1680
Step-by-step explanation:
Note the simple interest formula:
Interest = (Principal)(rate)(time)
Principal = $6000
Rate = 7% = 0.07
Time = 4
Plug in the corresponding numbers for the corresponding variables.
I = (P)(R)(T)
I = (6000)(0.07)(4)
Multiply.
I = (24000)(0.07)
I = 1680
Interest is $1680.

The linear equations are given as follows:
- For diagonal AC: .
- For diagonal BD: .
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For diagonal AC, the line contains points (-3,3) and (3,-3), hence the line is:
y = -x.
In standard form:
.
For diagonal BD, the line contains points (3,3) and (-3,-3), hence the line is:
y = x.
In standard form:
.

Answer:
Choice C
Step-by-step explanation:
The quadrant in which an angle lies determines the signs of the trigonometric functions sin, cos and tan
If an angle Θ lies in quadrant IV, cos(Θ) is positive and both sin(Θ) and tan(Θ) are negative
Two of the trigonometric identities we can use are
1. and
2.
Using identity 1, we can solve for cos(s) and cos(t)
Since both angles lie in quadrant IV, both cos(s) and cos(t) must be positive so we only consider the positive signs of both values
Using identity 2, we can solve for cos(s-t)
Multiplying numerator and denominator of the first term by gives us the final expression as
Answer:
I think d. Sorry if I am wrong.
Step-by-step explanation:
Answer:
x = 37°
Step-by-step explanation:
the sum of the exterior angles of a convex polygon is 360° so the sum of all the angles must yield to 360°.
just a trial!!!!!
x+2x+x+10+x+18+3x+x-1=360°
9x=333
x= 37°
