Identify the solution(s) of n2 – 5n = 24.
Answer:
n=-3 or n=8
Step-by-step explanation:
Let's solve your equation step-by-step.
n2−5n=24
Step 1: Subtract 24 from both sides.
n2−5n−24=24−24
n2−5n−24=0
Step 2: Factor left side of equation.
(n+3)(n−8)=0
Step 3: Set factors equal to 0.
n+3=0 or n−8=0
n=−3 or n=8
Answer:
n=−3 or n=8

Answer:
D
Step-by-step explanation:
When tossing a coin, there are two possibilities, heads or tails, thus one can rule out the first option. When rolling a pyramid-die, then there are four different possibilities, each one with an equally likely chance, and each one's outcome is non-dependant on the outcome of the coin toss. Thus options (B) and (C) can be ruled out. Therefore, option (D) is the only remaining valid option.

An environmentalist is studying a certain microorganism in a sample of city lake water. The function h(x) = 146(1.16)ˣ gives the number of the microorganisms present in the water sample at the end of x weeks. Which statement is the best interpretation of one of the values of the function? *
F. After 1 week, there will be 146 microorganisms in the water sample.
G. The initial number of microorganisms in the water sample was 16.
H. The number of microorganisms decreases by 84% each week.
J. The number of microorganisms increases by 16% each week.
Answer:
j
Step-by-step explanation:
The correct statement is J.
The number of microorganisms increases by 16% each week.
What is exponential equation?Exponential equations, as the name suggests, involve exponents. We know that the exponent of a number (base) indicates the number of times the number (base) is multiplied.
Given that a function h(x) = 146(1.16)ˣ, we need to check which statement is correct regarding the function,
The standard form is, A = A₀(1+r)ⁿ
A = final amount
A₀ = initial amount
r = rate
n = time
So, 1+r = 1.16
r = 0.16
So, checking the options =
F is incorrect because the number is increasing so it can be 146 after 1 week also,
G is incorrect because the initial amount is 146.
H is incorrect because the number is increasing.
J is correct because the number is increasing by 16%.
Hence the correct statement is J.

An observer standing on the southern bank of a river sees a tree that is much more than 100 feet downstream on the northern bank of the river. The angle formed by the southern bank and the line from the observer to the tree is 15 ∘. After walking 100 feet downstream, the observer measures the angle formed by the southern bank and the line to the same tree to be 25 ∘. Find the width of the river. (can you show the work please)(also the drawing please)
Answer:
[tex]63\ \text{ft}[/tex]
Step-by-step explanation:
The distances are shown in the figure
[tex]\tan25^{\circ}=\dfrac{p}{b}\\\Rightarrow p=b\tan25^{\circ}[/tex]
[tex]\tan15^{\circ}=\dfrac{p}{b+100}\\\Rightarrow p=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b\tan25^{\circ}=b\tan15^{\circ}+100\tan15^{\circ}\\\Rightarrow b=\dfrac{100\tan15^{\circ}}{\tan25^{\circ}-\tan15^{\circ}}\\\Rightarrow b=135.08\ \text{ft}[/tex]
[tex]p=b\tan25^{\circ}=135.08\times\tan25^{\circ}\\\Rightarrow p=62.99\approx 63\ \text{ft}[/tex]
The width of the river is [tex]63\ \text{ft}[/tex].

Lucy Liu went shopping at Hollister with her friends together they spent a mean price of $40 on eight sweaters the first step and sweaters cost $50 $55 $30 $35 $39 $40 and $42 how much in dollars does the eighth sweater cost
Answer:he eighth sweater costs $29
Step-by-step explanation:
Let the price of the eighth sweater be re[presented as X
We know that
Mean Price =Total sum of cost of sweater bought/ Number of sweater'
Plugging in our known values we have that
40=$50+ $55+ $30+ $35+ $39+ $40 + $42+X /8
8 X 40 =291 +X
320=291 +X
X =320-291
X=29
Therefore, the eighth sweater costs $29
