(A) because a right angle is 90 degrees and has a equal eqivalent to get to 100
Lana71 [14]3 years ago
6 0

Answer:

Option A is true

Step-by-step explanation:

Consider a right triangle ABC right angled at B.

Then we have A+C=90 since sum of all 3 angles =180

A and C are complementary

A has opposite side as BC and hypotenuse as AB

sin A = BC/AB

Consider angle B.

B has adjacent side as BC and hypotenuse as AB

So cos B = BC/AB

i.e. sin A = cos B

Hence we have option A to be true.

The graph of f(x) was vertically translated down by a value of k to get the function g(x) = 5x + k. What is the value of k? A -7
Nadya [2.5K]

Answer:

{\boxed{\text{A. }\math{k = -7}}

Step-by-step explanation:

The general rule for vertical translation of a function ƒ(x) ⟶ ƒ(x) + k .

A positive value of k means that the graph is shifted up by k units.

The graph of ƒ(x) was shifted from (0, 1) to (0, -6).

\text{The graph was shifted down by seven units, so }{\boxed{\mathbf{k = -7}}

There are 1500 bees in a colony. Each month, the number of bees decreases by 12%. There are 800 flowering plants in a garden. Ea
Evgen [1.6K]
 So the answer to this question is:

A= bees: f(t) = 1500 × (0.88)∧t

 plants: g(t) = 800 - 25×t

B: (Bees) 1500 × (0.88)∧6= 696.60
After 6 months (696 bees ):
800 - 25×6 = 650 (Flowering Plants)
After 6 months:

650 flowering plants

C: 1500 × (0.88)∧t=800 - 25×t
t = 6.779965672

Answer is it will take 7 months or 6 for the bees and the plants.
Hope this helps!
