Answer:
Step-by-step explanation:
This is a quadratic equation. We'll find the discriminant, but must first rewrite this equation in standard form:
5w2 – 2w + 4 = -4 + 4, or 5w^2 - 2w + 4 = 0
The coefficients of the w terms are {5, -2, 4}
and so the discriminant b^2 - 4ac is 4 - 4(5)(20) = -396
Because the discriminant is negative, we know that there will be two unequal, complex solutions.
The depth of a river at flood stage is marked as "O" on a tall pole in the middle of a riverbank. The pole is marked in 1-foot intervals above
and below 0 to show the current depth of the water.
Drag a value and a word to the blanks to complete the sentence.
When the water level is at the "-4" mark on the pole, the river is
feet
the flood stage.
Answer:
When the water level is at the "-4" mark on the pole, the river is 4 feet below the flood stage.
Step-by-step explanation:
Given
[tex]Flood\ stage = 0[/tex]
Required
What does -4 represents
From the question, we can deduce that:
[tex]Above = +ve\ intervals[/tex]
[tex]Below = -ve\ intervals[/tex]
-4 belongs to the "below" category.
Hence, -4 mark represents 4 feet below the flood stage

Jay places $3200 in an investment account earning 4.1% interest compounded weekly. How much money would he have in the account after 5 years, if he made no deposits or withdrawals during that time?
Answer:
A = $3,926.71
Step-by-step explanation:
Given: Principal (P) = $3200, Annual Rate (R) = 4.1%, Time = 5 years
To find: How much money would he have in the account after 5 years, if he made no deposits or withdrawals during that time?
Formula: [tex]A = P(1 + r/n)^nt[/tex]
Solution: Compound interest is one of the most important concepts to understand when managing your finances. It can help you earn a higher return on your savings and investments, but it can also work against you when you're paying interest on a loan
First, convert R as a percent to r as a decimal
r = R/100
r = 4.1/100
r = 0.041 rate per year,
Then solve the equation for A
A = P(1 + r/n)[tex]^{nt}[/tex]
A = 3,200.00(1 + 0.041/12)[tex]^{(12)(5)}[/tex]
A = 3,200.00(1 + 0.003416667)[tex]^{(60)}[/tex]
A = $3,926.71
Hence, Jay would have $3,926.71 after 5 years is if he made no deposits or withdrawals during that time.

Please find attached a diagram explaining the question
this would be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
15² + 19²
225 + 361
586
the square root of 586 = 24 miles
