Pooja's plant began sprouting 2 days before Pooja bought it, and she had it for 98 days until it died. At its tallest, the plant

was 30 centimeters tall.

Which number type is more appropriate for the domain of h?
A. Integers
B. Real numbers

Solution:

Total number of Days that Pooja's plant survived= 2 + 98 = 100 Days=(t)

Longest Height obtained by plant = 30 cm= h

As the two , i.e number of Days lived by plant and it's longest height obtained are directly proportional.

We will solve it by unitary method.

100 Days = 30 cm

1 cm =  Days

If height of the plant is h cm ,and  amount of time taken is t days, then

h(t) cm = ,for t=0,1,2,3,4,5,6....we get different values of h.

Answer:

B. Real numbers

C. -2≤ t ≤98

Step-by-step explanation:

t is the no. of days.

There can be 2.5 days too,

So domain should be Real numbers

t days after she bought it,

So 2 days before t = -2

So, -2≤ t ≤98

Find the slope of the line y=-5/4x+3
aalyn [17]

Hello!

The slope intercept equation for a line is y=mx+b, where b is the y-intercept, and m is the slope. As you can see, the slope is always multiplied by x.

As you can see, -5/4 is multiplied by x. Therefore, our slope is -5/4.

I hope this helps!

Find the inverse of the function f(x)=4x^3-7​
GuDViN [60]

Answer:

f^-1(x)=³√[(x+7)÷4]

Step-by-step explanation:

f(x)=4x^3-7

y=4x^3-7

interchange 'y' with 'x'

x=4y^3-7

make y the subject

4y^3=x+7

divide by 4 both sides

y^3=(x+7)÷4

multiply by the cube root both sides

³√(y^3)=³√[(x+7)÷4]

y=³√[(x+7)÷4]

f^-1(x)=³√[(x+7)÷4]

Help with this question, ASAP PLEASE!! SHOW YOUR WORK!!

Simplest polynomial function is x^4-x^3-11x^2+9x+18.

Solution:

Given data:

Zeroes are 3i, –1, 2.

3i is a complex root of the function.

If 3i is a zero of the polynomial then –3i is also a zero of the polynomial.

Therefore zeroes are 3i, –3i –1, 2.

By factor theorem,

If a is zero of the function, then (x – a) is a factor of the polynomial.

So, the factors are (x – 3i), (x + 3i), (x + 1), (x –2).

On multiplying the factors, we get the polynomial.

(x - 3i) (x + 3i) (x + 1) (x -2)

            =(x^2+3ix-3ix+(3i)^2)(x^2-2x+x-2)

            =(x^2-9)(x^2-x-2)

Since the value of i^2=-1

            =x^2(x^2-x-2)-9(x^2-x-2)

            =x^4-x^3-2x^2-9x^2+9x+18

            =x^4-x^3-11x^2+9x+18

Simplest polynomial function is x^4-x^3-11x^2+9x+18.
