4x²-12x-7=0

4x²-14x+2x-7=0

2x(2x-7)+1(2x-7)

(2x+1)(2x-7)

x=3.5 or x=-0.5

The science club sponsors and ordering In church for the boys and girls in science called their forty-five sure science club num
Oliga [24]

Answer:

The Science club would required 15 packs of caps and 9 packs of shirts to fulfill the needs of each member.

Step-by-step explanation:

Given:

Number of caps in each pack = 3

Number of Shirts in each pack = 5

Total members of club = 45

Number of caps needed = 45

Number of shirts needed = 45

we have to find the least number of packs of caps and shirts that they need to buy in order to fulfill the needs of each member.

Solution:

Now we can say that;

number of packs of caps required can be calculated by Number of caps needed divided by Number of caps in each pack.

framing in equation form we get;

number of packs of caps required = \frac{45}{3} = 15\ packs

Also We can say that;

number of packs of Shirts required can be calculated by Number of Shirts needed divided by Number of Shirts in each pack.

framing in equation form we get;

number of packs of Shirts required = \frac{45}5} = 9\ packs

Hence The Science club would required 15 packs of caps and 9 packs of shirts to fulfill the needs of each member.

How can you determine if a function is exponential or not without graphing?
ddd [48]
You are looking for several things when determining if a function is exponential or not.

An exponential function needs three things. A base, a power which is always a variable, and a constant.

Let me write a random exponential function and I’ll use it as an example.

f(x)=100x1.05^x

This is an exponential function because the c (constant) is 100. The c usually is about a population or object that is increasing.

The base is 1.05 which is usually a percentage increase.

Then the power which is x and this controls the time. It could be per day, year, and etc.

All of these factors contribute to the exponential function. If you have any questions ask, don’t be shy. :)
