Answer:
This is decay. The exponent has a negative sign. The reciprocal of 2 is 0.5. So N(t) can be rewritten as 0.5^(t/8). The base is fraction less than 1, which is decay.

Answer:
x = 5
Step-by-step explanation:
According to triangle angle bisector theorem, the ray divides the opposites side of the triangle into segments that are proportional to the other two sides.
So,
[tex]\frac{x-1}{x-2} = \frac{12}{9}\\\\\frac{x-1}{x-2} = \frac{4}{3}\\\\3(x-1) = 4(x-2)\\\\3x - 3 = 4x - 8\\\\4x - 3x = -3 +8 \\\\x = 5[/tex]

laraba has x naira. kunle has 15 naira less than laraba. together, the number of naira they have is:
A x- 15
B 2x
C 2x-15
D 2x+15
E 15
9514 1404 393
Answer:
C. 2x -15
Step-by-step explanation:
The respective numbers of naira are ...
laraba: x
kunie: x-15 . . . . . 15 less than laraba
Then the total is ...
laraba + kunie = x +(x -15) = 2x -15 . . . . matches choice C
Take the common logarithm of both sides of
the equation. Use the power law to bring
the exponent (2x+1) down as a factor.
5(2x+1) = 8
Step 1: Take the common logarithm of both sides of the equation. Use the power property to bring the exponent, (2x+1), down as a factor.
Step 2: Solve the equation from step 1 for x. Round your final answer to the nearest hundreth.
(2x+1)*log(5) = log(8)
2x+1 = log(8)/log(5) = ~ 1.29203
2x = 0.29203
Bapaphi earns 360 a week.He gets a pay rise of 10%.find his new wages a week.
Answer:
396
Step-by-step explanation:
100% = 360
10% = 100% * (10/100) = 100%/10 = 360/10 = 36
previous salary plus the 10% raise = 360 + 36 = 396 =

The mean number of rushing yards for one NFL team was less than 105 yards per game. If a hypothesis test is performed, how should you interpret a decision that rejects the null hypothesis
Answer:
Null hypothesis rejected means that there is significant evidence to conclude that the team's mean rushing yards per game is less than 105 yards.
Step-by-step explanation:
The mean number of rushing yards for one NFL team was less than 105 yards per game.
At the null hypothesis, we test if the mean number of rushing yards for the team was the league's mean, which is close to 105 yards per game, that is:
[tex]H_0: \mu = 105[/tex].
At the alternate hypothesis, we test if there is significant evident to conclude that this team average is less than 105 yards per game, that is:
[tex]H_1: \mu < 105[/tex]
How should you interpret a decision that rejects the null hypothesis?
Null hypothesis rejected means that there is significant evidence to conclude that the team's mean rushing yards per game is less than 105 yards.

The length of a rectangle is six times its width. If the perimeter of the rectangle is 126 in, find its length and width.
Answer:
Length = 54 inches and width = 9 inches.
Step-by-step explanation:
Let the width be x in , then the length is 6x in.
So 2*x + 2*6x 126
14x = 126
x = 9 in.
So L = 6*9 = 54 in, and W = 9 in.
Step-by-step explanation:
Perimeter = 2l + 2w
but;
Perimeter = 126
lenght = 6w ( let the width be the variable w)
126 = 2(6w) + 2(w)
126 = 12w + 2w
126 = 14w
126/14 =w
w = 9
Therefore width is 9
and length = 6× 9 = 54
4. Function h describes the height of a ball, in inches, after n bounces and is defined by
the equation h(n) = 120 * (4/5)^n
Could h(n) be 150? Explain how you
Answer:
NO
Step-by-step explanation:
(4/5)^n will always be ≤ 1 for any positve n
The equation h ( n ) = 150 is false
No , the height of the ball cannot be 150 inches
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
h ( n ) = 120 x ( 4/5 )ⁿ
Now , substitute the value of h ( n ) = 150 , we get
150 = 120 ( 4/5 )ⁿ
Divide by 120 on both sides of the equation , we get
150 / 120 = ( 4/5 )ⁿ
On simplifying the equation , we get
5/4 = ( 4/5 )ⁿ
The equation is not true because we have a exponential decay function here. This height of the ball decreases with each bounce.
At bounce 0 the height of the ball is 120 inches, and then continuously decreases with a common factor of 4/5
Therefore , the value of h ( n ) can never be 150
Hence , the equation h ( n ) = 150 is false
