Without using a calculator, determine the number of real zeros of the function

Natalija [7]

Answer:

1, -6

Step-by-step explanation:

Since there are alike numbers, add them together.

4x+x= 5x

Now the function is: f(x)= $x^{2}$ +5x-6

The function is in $a^{2}$ +bx+c form.

So find the factors of a x c = b.

Factors of -6(a) that fits (b)5 is (-1,6).

Then you just factor it:

f(x)= $x^{2}$ +5x-6

(x-1)(x+6)

x-1= 0 x+6=0

+1 +1 -6 -6

x=1 x=-6

Those are the real zeroes: 1, -6

Echo is creating a garden that is 36 feet wide and can fit one row of shrubs. Each shrub is 4.5 feet wide. Each shrub costs $15.

sashaice [31]

Answer:

Echo can plant a maximum of 8 shrubs.

The total cost for Echo's shrubs is = 8 $\times$ $15.32 = $122.56

Step-by-step explanation:

i) Garden is 36 feet wide

ii) Each shrub is 4.5 feet wide.

iii) therefore the maximum number of shrubs that can be planted are

$= \frac{36}{4.5} = 8$

Therefore Echo can plant a maximum of 8 shrubs.

Therefore the total cost for Echo's shrubs is = 8 $\times$ $15.32 = $122.56

What's the ratio in simplest form 20 and 60

Natalija [7]

Ok so 7:12 is already in it's simplest form because there is nothing that can go into both 12 and 7 (which is a prime number). So in fraction form it would be 7/12

8:10, so a number than can go into both 8 and 10? 2 can go into 8 4 times, and 10 5 times. So the fraction would be 4/5 which is in simplest form (5 is prime) 

25:50, again, what can go into both 25 and 50? 5 can. 5x5= 25 5x10=50. The fraction would be 5/10, which can be reduced to 1/2. 

80:60, 10 can go into both of them. 8/6 which can be reduced to 4/3 (2 goes into 8 4 times and 2 goes into 6 3 times) 

78:780, 2 can go into 78 32 times and can go into 780 390 times. 32/390 can be reduced to 16/195, which I believe is in it's simplest form (no number can go into both 16 or 195 evenly). 

All the other ratios are solved similarly, so I think you can do it. 
XD hopefully I explained it correctly, but you should also ask an adult to help you and/or correct your homework when you're done.

Assume that men's weights are normally distributed with a mean of 172 lb and standard deviation of 29 lb (national health survey

dezoksy [38]

The probability is 0.0606.

We find the z-score associated with this sample using the formula:

$z=\frac{X-\mu}{\frac{\sigma}{\sqrt{n}}}$

Using our information, we have:
$z=\frac{167-172}{\frac{29}{\sqrt{81}}}=-1.55$

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this score is 0.0606.
