Answer:
270.06
How to solve:
Write a function:
f(t)=270(1+0.001)^{t/10}
23 years→23/10→2.3 decades
Plug in t=2.3
f(2.3)=270(1+0.001)^{2.3/10}
=270.062076106
≈270.06
Answer:
39
Step-by-step explanation:
The angles are equal. This means that the triangle is equilateral and all the sides are equal to each other.
Set any two sides equal to each other.
2x - 3 = x + 5
x - 3 = 5
x = 8
Now substitute this x value into all the sides and add the numbers up.
2(8) - 3 = 16 - 3 = 13
So we know all 3 sides equal 13.
13 * 3 = 39
Answer:
406
Step-by-step explanation:
Five consecutive positive integers = x, (x+1), (x+2), (x+3), (x+4)
x + (x+1) + (x+2) + (x+3) + (x+4) = 2020
5x + 10 = 2020
5x = 2020-10
5x = 2010
x = 2010÷5
x = 402
The largest of the number is = x+4
x+4 = 402 + 4 = 406
The measure of angle A is 144.3 degrees and the angle to cut the molding is 54.3 degrees
<h3>How to solve for angle A?</h3>
Start by solving the acute part of angle A using the following sine function
sin(Ax) = (30 - 4)/32
Evaluate the quotient
sin(Ax) = 0.8125
Take the arc sin of both sides
Ax = 54.3
The measure of angle A is then calculated as:
A = 90 + Ax
This gives
A = 90 + 54.3
Evaluate
A = 144.3
Hence, the measure of angle A is 144.3 degrees
<h3>The angle to cut the molding</h3>
In (a), we have:
Ax = 54.3
This represents the angle where the molding would be cut
Hence, the angle to cut the molding is 54.3 degrees
