Write an exponential function for the value, y, after x years

Anon25 [30]

Step-by-step explanation:

Step 1: Set x equal to 0 to find the y-int

$y = 10000(1 - 0.40)$ → Not an exponential equation

$y=10000(1-0.40)^0$ → 10,000 → Works for first test

$y = 10000(1-0.60)^0$ → 10,000 → Works for first test

$y = 10000(1+0.40)^0$ → 10,000 → Works for first test

Step 2: Set x equal to 1

$y=10000(1-0.40)^1$ → 6,000 → Works for second test

$y = 10000(1-0.60)^1$ → 4,000 → Does not work for the second test

$y = 10000(1+0.40)^1$ → 14,000 → Does not work for the second test

Answer: The answer is Option B

From his eye, which stands 1.61 meters above the ground, Jacob measures the angle

bixtya [17]

Step-by-step explanation:

we have a right-angled triangle, that is "hovering" 1.61 m above the ground.

the Hypotenuse (the side opposite of the 90 degree angle) is the line of sight from the eye to the top of the skyscraper.

one leg is the height of the skyscraper (minus the 1.61 m).

the other leg is the ground distance from Jacob to the skyscraper (281 m).

we know already 2 angles : the 90° angle between the ground distance and the skyscraper height. and the 25° between the ground distance and the line of sight.

and as we know that the sum of all angles in a triangle is always 180°, we know that the third angle (between the line of sight and the skyscraper height) is

180 - 90 - 25 = 65°

now we can use the law of sines

a/sin(A) = b/sin(B) = c/sin(C)

(the ratio between a side and its opposing angle)

to get all missing side lengths.

the 25° angle is opposite of the skyscraper height, and the 65° angle is opposite of the ground distance (the only side length we know so far).

so,

height/sin(25) = 281/sin(65)

height = 281 × sin(25)/sin(65) = 131.0324519... m

to get the full height of the skyscraper, we need to add the 1.61 m that the described triangle was "hovering" above ground.

therefore, the height of the skyscraper is

131.0324519... + 1.61 = 132.6424519... ≈ 132.6 m

Question 12 Multiple Choice Worth 1 points)

serg [7]

Answer:

y - 3x = -10

Step-by-step explanation:

Complete question

Choose the equation below that represents the line passing through the point (2, -4) with a slope of 3

The standard equation of a line in point-slope form is y-y0 = m(x-x0)

Given

x0 = 2

y0 = -4

alope m = 3

Substitute

y - (-4) = 3(x - 2)

y + 4 = 3(x - 2)

y + 4 = 3x - 6

y - 3x = -6 - 4

y - 3x = -10

Hence the required equation is y - 3x = -10

Ill mark brainliest if correct

9966 [12]

Answer:

C) 36

Step-by-step explanation:

y = a(b^x) = a(1 + r)^x

Here, 1 + r = 1 + 0.36, so 0.36 is the rate.

0.36 = 36%

Answer: C) 36

-6/7,-3/7,0,3/7 .... create a formula that explains the arithmetic sequence

LenKa [72]

The formula that explain the arithmetic sequence is $a_{n}=\frac{3}{7}n-\frac{9}{7}$

Step-by-step explanation:

The formula of the nth term in an arithmetic sequence is

$a_{n}=a+(n-1)d$ , where

a is the first term
d is the common difference between the consecutive terms

∵ $\frac{-6}{7}$ , $\frac{-3}{7}$ , 0 , $\frac{3}{7}$ are some terms of an arithmetic sequence

∵ The difference between two consecutive terms = $\frac{-3}{7}$ - $\frac{-6}{7}$

∴ The difference between two consecutive terms = $\frac{-3}{7}$ + $\frac{6}{7}$ = $\frac{3}{7}$

∴ The common difference = $\frac{3}{7}$

∴ d = $\frac{3}{7}$

∵ The first term is $\frac{-6}{7}$

∴ a = $\frac{-6}{7}$

- Substitute a and d in the formula above

∴ $a_{n}=\frac{-6}{7}+(n-1)\frac{3}{7}$

- Simplify the right hand side

∴ $a_{n}=\frac{-6}{7}+\frac{3}{7}n-\frac{3}{7}$

- Add like terms

∴ $a_{n}=\frac{3}{7}n-\frac{9}{7}$

The formula that explain the arithmetic sequence is $a_{n}=\frac{3}{7}n-\frac{9}{7}$
