Answer:
BC = 22
Step-by-step explanation:
This is an isosceles triangle.
2x - 24 = x - 2
2x = x - 2 + 24
2x = x + 22
2x -x = 22
x = 22
Only option 1 and 4 are true.
Points S, U, and T are the midpoints of the sides of ΔPQR.
ΔSUT is inside of ΔPQR. Points S, U, and T are the midpoints of ΔPQR.
Which statements are correct? Check all that apply.
1. QP = UT
2. One-halfTS = RQ
3. SU = PR
4. SU ∥ RP
5. UT ⊥ RP
Given to us,
S, U, and T are the midpoints of the sides of ΔPQR.
Using Triangle Midpoint Theorem, which states that the line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side.
Therefore, only option 1 and 4 are true.

The formula used for this is the same one used to find interest accrued in a bank account that compounds continuously. The only difference is that our r here, the rate, is a negative number because the carbon is deteriorating over time, whereas money grows over time. That formula is this one:
where A is what's left in the end, P is the initial amount of carbon, r is the rate at which it deteriorates (sometimes a k in other formulas, but same thing!) and t is the time in years. For us, that formula, filled in, looks like this:
First thing to do is to simplify that multiplication involving the exponents. Doing that gives us:
On your calculator, you have a 2nd button and an LN button. If you push 2nd and then LN you get this in your display:
and it's up to you to add the exponent on the e. Our exponent is the -.516. So do that and then multiply that result by 32 to get that your answer is 19.1 g of carbon remaining.
Answer:
h = 8.78
Step-by-step explanation:
Remark
Since this is a right angle triangle, you could find the area 2 different ways.
Area 1. Use the arms of the right angle to find the area.
Area = 1/2 * a * b
a = 9
b = 40
Area = 1/2 40 * 9
Area = 180 m^2
The other way is to multiply the height by the hypotenuse
h = ?
hypotenuse = 41
Area = 1/2 * 41 * h
But we already know the area
1/2 41 * h = 180 Multiply by 2
41 * h = 2 * 180
41 * h = 360 Divide by 41
h = 360 / 41
h = 8.78
Answer:
1. y = 2m + 4
2. y = 3m + 1
3. y = 2/3m +1
4. y = 4m -6
Will answer any questions in the comments
Step-by-step explanation:
1. 1 -> 5 = 4
6 -> 14 = 8
8/4 = 2
y = 2m + 4
2. 2 -> -3 = -5
-5 -> 10 = 15
5/15 = 3
y = 3m + 1
3. 9 -> -3 = -12
11 -> 3 = -8
-8/-12 = 2/3
y = 2/3m + 1
4. 3 -> -2 = -5
6 -> -14 = -20
-20/-5 = 4
y = 4m - 6
