Multiply the ones 472×7​

Mathematics
1 answer:
nydimaria [60]3 years ago
3 0

The answer you will get is 3304, and in order to get this, you could use a simple step which is adding, so we would do 472 + 472 + 472 + 472 + 472 + 472 + 472, which gives you 3304. Adding is much faster and easier way to do it to get your answer.

Hope this helped!

Identify the zeros of the function f(x) =2x^2 − 2x + 13 using the Quadratic Formula. SHOW WORK PLEASE!! I NEED HELP!!
babunello [35]

Answer:

x=\frac{1+5i} {2}   and  x=\frac{1-5i} {2}

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

in this problem we have

f(x)=2x^{2} -2x+13  

Equate the function to zero

2x^{2} -2x+13=0  

so

a=2\\b=-2\\c=13

substitute in the formula

x=\frac{-(-2)\pm\sqrt{-2^{2}-4(2)(13)}} {2(2)}

x=\frac{2\pm\sqrt{-100}} {4}

Remember that

i=\sqrt{-1}

so

x=\frac{2\pm10i} {4}

Simplify

x=\frac{1\pm5i} {2}

therefore

x=\frac{1+5i} {2}   and  x=\frac{1-5i} {2}

Given sin A = 12/13 and that angle A is in Quadrant 1,
UkoKoshka [18]

We have been given that \text{sin}(A)=\frac{12}{13} and angle A is in quadrant 1. We are asked to find the exact value of \text{cot}(A) in simplest radical form.

We know that sine relates opposite side of right triangle with hypotenuse.

\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

This means that opposite side is 12 units and hypotenuse is 13 units.

We know that cotangent relates adjacent side of right triangle with adjacent side.

\text{cot}=\frac{\text{Adjacent}}{\text{Opposite}}

Now we will find adjacent side using Pythagoras theorem as:

\text{Adjacent}^2=\text{Hypotenuse}^2-\text{Oppoiste}^2

\text{Adjacent}^2=13^2-12^2

\text{Adjacent}^2=169-144

\text{Adjacent}^2=25

Let us take positive square root on both sides:

\sqrt{\text{Adjacent}^2}=\sqrt{25}  

\text{Adjacent}=5

Therefore, adjacent side of angle A is 5 units.

\text{cot}(A)=\frac{5}{12}

Therefore, the exact value of cot A is \frac{5}{12}.
