Answer:

Decay

Step-by-step explanation:

Any "r" value between 0 and 1 indicates an exponential function in decay. The "r" value is the one in the parentheses and raised to the exponent. In this case, the value is 0.91. This number falls within the "r" value boundaries of a decaying exponential function.

Answer:

99.34 years

Explanation:

Given function:

Since the Independent variable is something that is modified or controlled in a scientific experiment, it is his age.

Answer:

He needs 8 half-cups.

Step-by-step explanation:

hi!

Monsieur Dufour needs 8 half cups of bread dough, because 4x2=8.

Step-by-step explanation:

for this we need to know the conversion rate between miles and kilometers :

1 mile = 1.60934 km

which means

1 km = 0.621371 miles

so,

70 m/h = 70×1.60934 km/h = 112.6538 km/h

compared to the 120 km/h limit in Canada, it is clear that the speed limit in Canada is higher.

the difference is

7.3462 km/h = 7.3462×0.621371 = 4.56471564 m/h

Hi!

We can see the river is a straight line.

This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.

Therefore:

[tex]x+2x+21=180[/tex]

Combine like terms:

[tex]3x+21=180[/tex]

Subtract 21 from both sides:

[tex]3x=159[/tex]

Divide both sides by 3:

[tex]x=53[/tex]

Therefore, the value of x is 53 degrees.

Answer:

x=10, first angle is 107, second angle is 73

Answer:

15 answers

Step-by-step explanation:

To solve this question we need to set up an equation.

Let's name the number of incorrect answers x.

We can set up an equation that's essentially:

(Points for correct answer)*(number of correct answers)+(points for incorrect answer)*(number of incorrect answers)=final score

When we plug in our numbers and variables it looks like this:

5(3)+(-2x)=-15

Simplify

15-2x=-15

Subtract 15 from both sides

-2x=-30

Divide both sides by -2

x=15

This means Smitha attempted 15 wrong answers, and that there were 18 questions in total.

The exponential function is given as 3.68 × (2.52)ˣ. Then the value of function at x = 6 will be 942.43.

The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.

If f(x) is an exponential function where f(2) = 23 and f(3) = 58.

Then the exponential function will be

f(x) = abˣ

If f(2) = 23, then we have

23 = ab² ...1

If f(3) = 58, then we have

58 = ab³ ...2

Then from equations 1 and 2, we have

a = 3.62 and b = 2.52

Then the function will be

f(x) = 3.68 × (2.52)ˣ

Then the value of f(6) will be

f(6) = 3.68 × (2.52)⁶

f(6) = 3.68 × 256.1

f(6) = 942.43

Answer:

$8927.1

Step-by-step explanation:

printed price is the actual price without including tax price

tax price= 9/100×9810

tax price= 0.09×9810= $882.9

printed price of the camera= 9810-882.9= $8927.1

Answer:

in terms of pi: 112.5pi mm squared

substituting pi for 3.14: 353.25 mm squared

Step-by-step explanation:

Surface area cone equation:

Πr2 + π*r*s

4.5^2 = 20.25pi

400 + 20.25 = 420.25

sqrt(420.25) = 20.5

20.25pi + 92.25pi = 112.5pi

Answer: Solve for a: a = [tex]\frac{8n+1}{n}[/tex]

Solve for n: [tex]n=\frac{1}{a-8}[/tex]

Step-by-step explanation:

solve for n: Move all terms to the left side and set them equal to zero. Then set each factor equal to zero.

solve for a: Divide each term in an = 9 + (n−1) ⋅ 8 by n and simplify.

The hundredth number in the series as defined in the task content is; 107.

According to the task content;

The first term of the sequence of numbers is; 8 and evidently, the common difference of the sequence is; 9-8 = 1.

On this note it follows that the 100th number is;

T(100th). = 8 + 99(1) = 107.

Answer:

where

r radius of semicircle

→ ½ * 22/7 * r² = 35

→ 11/7 * r² = 35

→ r² = 35*7/11

→ r² = 245/11

→ r² = 22.77

→ r = √22.77

→ r = 4.77

Therefore,

Diameter = 2*4.77
