Answer:

5x^2 - 4x - 3 = 0

Step-by-step explanation:

For the equation

ax^2 + bx + c = 0

the  roots are   [-b +/- √(b^2 - 4ac)] / 2a

So comparing the terms to the values in the question:

a = 5

b = -4

c = -3

$800 at 4.25% simple interest for 6 years
charle [14.2K]
A = $992.00

(I = A - P = $192.00)

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.

Solving our equation:
A = 800(1 + (0.04 × 6)) = 992 
A = $992.00

The total amount accrued, principal plus interest, from simple interest on a principal of $800.00 at a rate of 4% per year for 6 years is $992.00.

The probability of randomly drawing a red card from a bag that contains red, blue, and green cards is 3/10. What is the probabil
Katarina [22]
If the probability of drawing a red card is 3/10, then if we take this fom a whole, 10/10, we can find the probability of not choosing a red card.
10/10-3/10=7/10

The probability of not drawing a red card is 7/10 or 70%.

What is an equation of the circle with center (-5,4) and a radius of 7?
OleMash [197]

Answer:

Option D

Step-by-step explanation:

Given:

  • Center point: (-5, 4)
  • Radius: 7

<u>Formula:</u>

Equation of circle: (x - h)² + (y - k)² = r²

[Where (h, k) is the center point and "r" is the radius of the circle]

<u>Substitute the coordinates of the center point in the formula:</u>

Given center point: (-5, 4)

∴ x-coordinate of center point (h) = -5; y-coordinate of center point (k) = 4

  • ⇒ (x - h)² + (y - k)² = r²
  • ⇒ [x - (-5)]² + [y - 4]² = r²

<u>Substitute the radius in the formula:</u>

Given radius: 7

  • ⇒ [x - (-5)]² + [y - 4]² = r²
  • ⇒ [x - (-5)]² + [y - 4]² = (7)²

<u>Simplify both sides of the equation:</u>

  • ⇒ [x + 5]² + [y - 4]² = (7)(7)
  • ⇒ [x + 5]² + [y - 4]² = 49  <u>(Option D)</u>

Therefore, Option 4 is correct.

PLEASE HELP THANKS

AC would be equivalent to 4. I know that the triangle is a 90, 45, 45 triangle which means 2 of the angles AND sides are equivalent to each other. Since angle B is 45 degrees angle C has to be 45 degrees. Same goes for the sides. Since AB=4, AC=4. It wouldn't be BC bc that's the hypotenuse or the longest part of the triangle. AC wouldn't be equal to 2 since it won't follow the rule of a 90, 45, 45 triangle. :|
