Working out the expression 7(3ˣ) is first to calculate the value of 3ˣ then multiply the answer to 7.
For example, let x = 2
Then 7(3ˣ) = 7(3²) = 7 × 9 = 63
With the same value of x = 2, calculating 21ˣ = 21² = 441, which isn't the same answer with the expression 7(3ˣ)
1/2=5/10
1/5=2/10
1/2+1/5
=5/10+2/10
=7/10
So your answer is 7/10
The two triangles on the side are 18 in^2 and the square in the middle is 36 in^2. So in total, it has an area of 72 in^2
The measure of angle QPS in circle C is 112°
<h3>What is a
circle?</h3>
A circle is the locus of a point such that its distance from a fixed point known as the circle center is always constant. The sum of angles in a circle is 360 degrees.
From the circle:
PQ is parallel to SR, hence: ∠PQR + ∠QRS = 180°
∠PQR + 68 = 180
∠PQR = 112°
Also, PS = QR (from the endpoint of the diameter), hence:
∠QPS = ∠PQR = 112°
The measure of angle QPS in circle C is 112°
