Which is a quantitative variable? A) brand of pancake mix B) flavor of pancakes, such as chocolate chip C) servings per box of p
Usimov [2.4K]

Answer:

Step-by-step explanation:

A quantitative variable is the one which is represented numerically and not with words.

Hence option (C) is the quantitative variable as servings per box are represented by numbers. (eg. if in a box of 16 cookies, 1 serving = 1 cookie, then the servings per box will be 16)

Suppose z is a complex number (a point in the plane) with angle 30 degrees and radius 2. Suppose w is a complex number with angl
nordsb [41]

Write each number in complex polar form:

z=2e^{i\cdot30^\circ}

w=5e^{i\cdot60^\circ}

When you multiply two exponential expression with the same base (here, that's <em>e</em>), you end up adding the exponents, so that

zw=(2\cdot5)e^{i\cdot30^\circ+i\cdot60^\circ}=10e^{i\cdot90^\circ}=10i

so the angle of the product <em>zw</em> is 90°.

I’ve wasted around 100 points for people to not answer or say random stuff just to get points.
Colt1911 [192]

Answer: 72

Because the picture shows that there's a 90 degree angle in the bottom. We know that the bottom triangle is a 45-45-90 triangle. So the length of one side   is 18 because a 45 45 90 triangle has two sides that are equivalent (x) and one side that is x\sqrt{2} \. So now that we know the length of one side is 18, we know the lengths of all 4 sides. Adding them up ( 18 + 18 + 18 + 18) gives 72, which is the perimeter.

A flagpole is 20 feet tall is casting a shadow that is 8.2 feet long at what angle is the sun hitting the ground
Novay_Z [31]

Answer:

∅ = 67.71°

Step-by-step explanation:

The flag pole is 20 ft tall is casting a shadow that is 8.2 ft long .At what angle is the sun hitting the ground. The illustration forms a right angle triangle.

The right angle triangle has an hypotenuse, opposite and adjacent sides. The flag height forms the opposite side. The shadow forms the adjacent side . The angle the sun is hitting the ground can be using SOHCAHTOA principle.

using Tan

tan ∅ = opposite / adjacent

tan ∅ = 20/8.2

tan ∅ = 2.4390243902

∅ = tan⁻¹ 2.4390243902

∅ = 67.7063708403

∅ = 67.71°
