So, we know that the quadratic formula is x=-b+- the square root of b^2-4ac and all of this divided by 2a. You might be like "wow, where did all of these come from?" It is actually really easy. So, let's take your first equation: 2x^2-19x+24=0. So, let us look at the standard form for a quadratic formula: a^2+b+c=0. Now, If you look at the normal equation and the standard form for a quadratic, you will see that they are alike. Now, just match the letter with the number: a=2, b=-19, and c=24. Now that you know what each letter represents, you can plug everything into the equation x=-b+- the square root of b^2-4ac and all of this divided by 2a.

$25,000 is invested for 5 years with an APR of 3% and daily compounding.
Effectus [21]

Answer:

$29,045.69

Step-by-step explanation:

The total amount accrued, principal plus interest, with compound interest on a principal of $25,000.00 at a rate of 3% per year compounded 365 times per year over 5 years is $29,045.69.

A = P(1 + r/n)nt

A = 25,000.00(1 + 0.03/365)(365)(5)

A = 25,000.00(1 + 8.2192E-5)(1825)

A = $29,045.69

The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax, and the price of th
hichkok12 [17]

Answer:

Step-by-step explanation:

let x represent the number of markers.

Let y represent the cost for x boxes of markers.

If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be

Slope, m = (14 - 7)/(24 - 10)

m = 7/14 = 0.5

The equation of the straight line can be represented in the slope-intercept form, y = mx + c

Where

c = intercept

m = slope

To determine the intercept, we would substitute x = 24, y = 14 and m = 0.5 into y = mx + c. It becomes

14 = 0.5 × 24 + c = 12 + c

c = 14 - 12

c = 2

The equation would be

y = 0.5x + 2

(1) Mara has 4 garden plots. Each is 0.7 acre in area.
Fiesta28 [93]

Answer:

The total area covered by the garden plots is 2.8 acres.

Step-by-step explanation:

Given that Mara has 4 garden plots.

The area of each garden plot = 0.7 acres

All 4 garden plots have an equal area as shown in the figure (Plots A, B, C, and D)

So, the total area covered by the garden plots = Sum of areas of all the 4 plots

= Area of plot A + Area of plot B + Area of plot C + Area of plot D

=0.7+0.7+0.7+0.7

=2.8 acres.

Hence, the total area covered by the garden plots is 2.8 acres.
