Write An Exponential Decay Function To Model The Situation In The Photo. Correct Answer Will Get A Brainliest,

Answers

Answer 1

Step-by-step explanation:

The formula for exponetial equation decay is

[tex]y = a(b) {}^{x} [/tex]

where a is the initial value and b is the decay factor.

A will be 56 since that our initial value.

b will be 0.9 since we are constantly decaying by 0.9.

so our equation is

[tex]y = 56(0.9) {}^{x} [/tex]

The measures of three angles of a triangle are given by (8x - 5), (2x)º, and (3x – 10). What is the measure of the largest angle? A 15° B 115° C. 35° D 150°​

Answers

Answer: 115°

Step-by-step explanation:

We should note that the sum of the angles that are in a triangle is equal to 180°, therefore we will add the angles given and equate them to 180°. This will be:

(8x - 5) + (2x) + (3x - 10) = 180

8x - 5 + 2x + 3x - 10 = 180

Collect like terms

8x + 2x + 3x = 180 + 5 + 10

13x = 195

x = 195/13

x = 15

The angles are:

8x - 5 = 8(15) - 5 = 120 - 5 = 115°

2x = 2(15) = 30°

3x - 10 = 3(15) - 10 = 45 - 10 = 35°

Therefore, the largest angle is 115°

What is Law of Cosines?

The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.

The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:

c² = a² + b² - 2ab cos(C)

where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.

Given data ,

Let the triangle be represented as ΔXYZ

And , the measures of the sides of the triangle are

z = 75 inches

x = 26 inches

And , the measure of ∠Y = 135°

We can use the Law of Cosines to find the length of y, since we know two sides and the included angle of the triangle.

The Law of Cosines states that:

c² = a² + b² - 2ab cos(C)

where c is the side opposite angle C, and a and b are the other two sides.

In this case, we want to find the length of side y, which is opposite angle Y. So we can write:

y² = x² + z² - 2xz cos(Y)

Substituting in the given values, we get:

y² = 26² + 75² + 2(26)(75) cos(135°)

Simplifying, we get:

y² = 676 + 5625 - 2925√2

y² ≈ 9163

Taking the square root of both sides, we get:

y ≈ 95.76

Rounding to the nearest inch, we get:

y ≈ 96 inches

Hence , the length of y, to the nearest inch, is 96 inches

Pls show work I really need help

Answers

Answer:

A 108 mm

Step-by-step explanation:

The computation is shown below:

As we know that

V = Bh

where

B denotes the area of the base

and h denotes the height of the prism.

Now

V = (1 ÷ 2 × 12.6 × 1.6) × 10.75

= 108.36 mm

= 108 mm

First you have to look at the way the shape is named based on order in each other. ABCD is congruent to GJIH. This means A will be congruent to G, and J will be congruent to B and so on. Same goes with side lengths, so that mean segment GH is congruent to AD based on the order of the name.

So x/3=9
You multiply by 3 on both sides to get x by itself.
So now your answer is x=27
