6 0

Answer:

g(f(x)) = -x^2 + 4

Step-by-step explanation:

What we simply have to do here is to put f(x) into g(x)

What this mean is that every x in g(x) will be represented by f(x)

Thus, we have it that

-x^2 - 1 + 5

= -x^2 + 4

Subtract 2x - 6 from 4x + 9
sp2606 [1]

Answer:

2x + 15

Step-by-step explanation:

When you subtract an expression from another expression, it will be on the right side of the subtraction sign.

(4x + 9) - (2x - 6)

First, let's distribute the negative sign.

(4x + 9) - 2x + 6

Now combine like terms.

4x - 2x + 9 + 6

2x + 15

This is the fully simplified expression.

Hope this helps!

A scientist placed fish eggs in a tank. Each day, twice the number of eggs from the previous day hatch. The expression 5 times 2
kykrilka [37]

Answer:  The answer is 20 eggs.


Step-by-step explanation:  Given that a scientist placed fish eggs in a tank. Also, each day, twice the number of eggs from the previous day hatch, .i.e, if 'x' number of eggs hatch on first day, then '2x' number of eggs will hatch on the second day.

The number of eggs that hatch on the sixth day is given by 5 times 2 to the second power.

So, the number of eggs got hatch on the sixth day is

E_6=5\times 2^2=5\times 4=20.

Thus, the answer is 20 eggs.

1. A weight suspended from a spring is set into oscillating motion by compressing it to a
Naya [18.7K]

Question:

Complete question for this is to find the equation for this and may be the graph.

Explanation:

As for the oscillation motion, initially peak is occurring hence it will be a cosine function with peak value of 3(cm).

To calculate time period, the whole cycle should be 360°

i.e.

cos (Xπ.t) = cos (360)

as the cycle completes at 1.2 sec hence by putting t=1.2, answer should be 360.

i.e.

X*180*t=360

X*180*1.2=360

X=5/3

So, the required equation is

f(x)=3.cos(5\frac{\pi }{2}.t)

Graph for this equation is attached here with this answer.

In graph,

x-axis: t=0 ~ t=1.2

y-axis: f(x)=-4 ~ f(x)=4
