Division

Step-by-step explanation:

PEMDAS

Parenthesis

Exponents

Multiplecation

You have both exponents and parenthesis, so your third step would be multiplecation, but you don't have that, so it would be division.

A population of 1,750 cheetahs decreases by 10% per year. How many cheetahs will there be in the population after 11 years? Roun

Triss [41]

Answer:

The answer is C. 546.

If a population decreases by 11%, that means that 89% (100% - 11% = 89%) of cheetahs remains each number. 89% can be expressed as 0.89, so to calculate the change of the population, we must each year multiply the number of cheetahs by 0.89.

After 1 year: 1750 * 0.89 ≈ 1558

After 2 years: 1558 * 0.89 ≈ 1387

After 3 years: 1387 * 0.89 ≈ 1234

After 4 years: 1234 * 0.89 ≈ 1098

After 5 years: 1098 * 0.89 ≈ 977

After 6 years: 977 * 0.89 ≈ 870

After 7 years: 870 * 0.89 ≈ 774

After 8 years: 774 * 0.89 ≈ 689

After 9 years: 689 * 0.89 ≈ 613

After 10 years: 613 * 0.89 ≈ 546

Susan is drawing a triangle. The first segment she draws is 6 centimeters in length, and the second segment is 8 centimeters lon

In-s [12.5K]

Answer:

B) less than 14 centimeters

Step-by-step explanation:

Given:

Length of 1 segment of triangle = 6 cm

Length of the 2 segment of the triangle = 8 cm

Angle between those 2 segments = 80°

We need to find the length of the 3 segment of the triangle.

Solution:

Now we know that;

By Triangle Inequality theorem which states that;

"The sum of the two side of the triangle must be greater than the third side of the triangle."

i.e The length of the third side should be lest than the sum of the other two sides.

Length of the third side $< 8+6$

Length of the third side

Hence The length of the third side should be less than 14 cm.

(PARABOLA? BRAINLIEST + 20 POINTS) A building has an entry the shape of a parabolic arch 22 ft high and 28 ft wide at the base.

Keith_Richards [23]

Check the picture below.

$\bf ~~~~~~\textit{parabola vertex form} \\\\ \begin{array}{llll} y=a(x- h)^2+ k\qquad \leftarrow \textit{let's use this one}\\\\ x=a(y- k)^2+ h \end{array} \qquad\qquad vertex~~(\stackrel{}{ h},\stackrel{}{ k}) \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \begin{cases} h=0\\ k=0 \end{cases}\implies y=a(x-0)^2+0 \\\\\\ \textit{we also know that } \begin{cases} x=14\\ y=-22 \end{cases}\implies -22=a(14-0)^2+0 \\\\\\ -22=a(14)^2\implies -22=196a\implies \cfrac{-22}{196}=a\implies -\cfrac{11}{98}=a \\\\[-0.35em] ~\dotfill\\\\ y=a(x-0)^2+0\implies \boxed{y=-\cfrac{11}{98}x^2}$
