Let
x--------> the number

we know that
11²=121
12²=144

then
x² must be greater than 121  and less than 144

case a) <span>√115
if x=</span><span>√115
then
 x</span>²=115-------> is not greater than 121

case b) <span>√121 
</span>if x=√121
then
 x²=121-------> is not greater than 121

case c) <span>√136
</span>if x=√136
then
 x²=136-------> is greater than 121 and is less than 144------> is ok

case d) <span>√150
</span>if x=√150
then
 x²=150------> is not less than 144

therefore

the answer is
√136

IS IT (A , B ) CAN SOMEONE HELP PLEASE !!!!!!!!!!!!!!!!!
andriy [413]

Answer: 1% is your answer

It's (1/100) * 100 or 1% is the percentage strength of a 1:100 solution.

Step-by-step explanation:

l NOTE:

l To change ratio strength to percent strength, it is

sometimes convenient to "convert" the last two zeros in

a ratio strength to a percent sign (%),

l change the remaining ratio to a common fraction, and

then to a decimal fraction in expressing percent.

l Examples:

l 1:100 =1/1% = 1%

l 1:200 = ½% = 0.5%

l 3:500 = 3/5% = 0.6%

l 1:2500 = l/25% = 0.04%

l 1:10,000 = 1/100% = 0.01%

Find the standard form of the equation of the hyperbola satisfying the given conditions: X intercept +/- 6; foci at (-10,0) and
uysha [10]

Answer:

\frac{x^{2}}{36} - \frac{y^{2}}{64}=1

Step-by-step explanation:

Given an hyperbola with the following conditions:

  • Foci at (-10,0) and (10,0)
  • x-intercept +/- 6;

The following holds:

  • The center is midway between the foci, so the center must be at (h, k) = (0, 0).
  • The foci are 10 units to either side of the center, so c = 10 and c^2 = 100
  • The center lies on the origin, so the two x-intercepts must then also be the hyperbola's vertices.

Since the intercepts are 6 units to either side of the center, then a = 6 and a^2 = 36.

Then, a^2+b^2=c^2\\b^2=100-36=64

Therefore, substituting a^2 = 36. and b^2=64 into the standard form

\frac{x^{2}}{a^2} - \frac{y^{2}}{b^2}=1\\We \: have:\\ \dfrac{x^{2}}{36} - \dfrac{y^{2}}{64}=1
