Can somebody help me

Mathematics
1 answer:
patriot [66]3 years ago
4 0

Answer:

Down below

Step-by-step explanation:

1. 3/4x-7-16, combine -7 and -16, 3/4x-23

2. -8+2y+4, combine -8 and 4, 2y+4

3. -4x+11x+3y, combine -4x and 11x, 7x+3y

4. 41+b-25b, combine b and -25b, 41-24b

5. -1/2(8x-2), distribute: -1/2*8x and -1/2*-2, -4x+1

6. $40, 15% off: 40(1.00-0.15)= $34

So simplifying expressions means to just combine like terms (e.g. 2 and 4, 5x and -18x, 7y and y, etc.)

Distribution means to apply the multiplication to the terms inside the parentheses (e.g. a(x+y) -> ax+ay)

Sales is just: original price * (1 - percent off by)

I hope this helps!

A grasshopper jumps off a tree stump. The height, in feet, of the grasshopper above the ground after t seconds is modeled by the
klasskru [66]

Answer:

Hence, Grasshopper will land on the ground after 1.5 sec.

Step-by-step explanation:

It s given that:

The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function:

h(t)=-t^2+\dfrac{4}{3}t+\dfrac{1}{4}

Now we are asked to find:

In how many seconds will the grasshopper land on the ground?

i.e. we have to find the value of t such that h(t)=0

i.e.

-t^2+\dfrac{4}{3}t+\dfrac{1}{4}=0

i.e. we need to find the roots of the given quadratic equation.

On solving the quadratic equation or plotting it's graph we could observe that the point where h(t)=0 are:

t=-\dfrac{1}{6},t=\dfrac{3}{2}

As time can't be negative hence we will consider:

t=\dfrac{3}{2}=1.5sec

Hence, grasshopper will land on the ground after 1.5 sec.
