What is the value of m, if the equation my2+2y−4=0 has exactly one root?
stich3 [128]

Answer:

m=\frac{-1}{4}

Step-by-step explanation:

A quadratic equation has one root if the discriminant is 0.

That is we need b^2-4ac=0 for this particular question.

Compare the following to find a,b, \text{ and } c:

ax^2+bx+c=0

my^2+2y-4=0

The variable x is representative of the variable y here.

a=m

b=2

c=-4

Plug in into b^2-4ac=0:

(2)^2-4(m)(-4)=0

4+16m=0

Subtract 4 on both sides:

16m=-4

Divide both sides by 16:

m=\frac{-4}{16}

Reduce:

m=\frac{-1}{4}

Work out the percentage change to 2 decimal places when a price of £57.99 is decreased to £49.99.
IRISSAK [1]

Answer:

Percentage change in price = 13.80%

Step-by-step explanation:

Given that:

Original price = £57.99

Decreased price = £49.99

Difference = Original price - Decreased price

Difference = 57.99 - 49.99

Difference = £8.00

Percent change = \frac{Difference}{Original\ price}100

Percent change = \frac{8.00}{57.99}*100

Percent change in price = 13.80%

Hence,

Percentage change = 13.80%

Find the volume and explain please ASAP.
olya-2409 [2.1K]

Answer:

1395in^3

Step-by-step explanation:

First find the volume of the cuboid, 15in x 9in x 7in = 945in^3

Then find the volume of the rectangular pyramid using the formula V=lwh/3, the total height is 17in so subtract the height of the cuboid from the total height, giving you 10in.

V=(15in)(9in)(10in)/3 = 450in^3

450in^3 + 945in^3 = 1395in^3

WILL GIVE BRAINLIEST! DUE TODAY! WILL GIVE EVERYTHING GOOD!!! HELPP!!! I REALLY NEED HELP ON THIS ONE!!!!
PtichkaEL [24]

Answer:

So its pretty simple

The table provided the Xs so you can just substitute the x in the eqaution becuase the eqaution gives you Y and your looking for Y.

For the first one

-3/4*-16+3=y

12+3=15

So Y is 15

DO the same for the others

Also I think your rate of change is wrong, I think it’s -3/4 but your choice really, I might be wrong
