XY bisects DF at point E. If DE=2y and EF=8y-3, find the value of DF​

Mathematics

Answer:

Step-by-step explanation:

If XY bisects DF at point E, then DE = EF.

Given DE = 2y and EF = 8y-3

2y = 8y-3

subtract 8y from both sides

2y-8y = 8y-8y-3

-6y = -3

y = 3/6

y = 1/2

y = 0.5

DF = DE+EF

DF= 2y+8y-3

DF = 10y - 3

DF = 10(0.5)-3

DF = 5-3

DF = 2

Answer:

7.405882353 years

Step-by-step explanation:

Simple interest is

A = P(1+rt)

Where A is the amount in the account

P is the principle invested

r is the rate and

t is the time

6593.75 = 5000( 1+ .0425*t)

Divide each side by 5000

6593.75/5000 = ( 1+ .0425*t)

1.31475 = ( 1+ .0425*t)

Subtract 1 from each side

.31475 = .0425t

Divide each side by.0425

.31475/.0425 = .0425t/.0425

7.405882353 = t

Which of the measurements would be the most helpful in determining the wavelength
In-s [12.5K]
So we want to know what do we need to measure to determine the wavelength of the wave on the image. A wavelength is the distance between peaks of the wave. More generally, the distance on which the wave shape repeats. So on the image we need to measure X to determine the wavelength. So the correct answer is X.

What is the correct answer please need help
Oduvanchick [21]

Answer:

52 cm^2

Step-by-step explanation:

Solve by splitting the figures into 2 parts and finding their areas separately:

Rectangle:

8 × 5 = 40

Triangle:

1/2 × b × h = 1/2 × 8 × 3 = 4 × 3 = 12

Total: 40 + 12 = 52

find a function whose second derivative is y''=12x-2 at each point (x,y) on its graph and y=-x+5 is tangent to the graph at the
pogonyaev
Start by integrating y'' twice to get function y(x).

y' = \int (12x - 2) dx = 6x^2 -2x + c \\  \\ y = \int (6x^2 -2x+c )dx= 2x^3-x^2 +cx+d

Next find value of coefficients 'c' and 'd' using the given tangent line
The slope of tangent line is equal to y' when x=1.

6x^2 -2x+c = -1, x = 1 \\  \\ 6-2+c = -1 \\  \\ c = -5

The tangent line intersects the curve y(x) when x = 1.
If x = 1, then y = 4  (From y =-x+5)

y = 2x^3 -x^2-5x +d , x = 1, y = 4 \\  \\ 2-1-5+d = 4 \\  \\ d = 8

Final Answer:
y = 2x^3 -x^2 -5x+8
