Step-by-step explanation:

in this condition we are given simple interest time and rate

so principal is missing so we should use the formula of principal that is

P=I×100/T×R

but we should convert that month in to years and we convert it by dividing it by 12.

What are the solutions to the quadratic equation 3(x – 42 = 752

Neporo4naja [7]

X=292.6

Step 1: distribute 3 through parentheses
3x-126=752

Step 2: move the constant to the right and change it sign
3x= 752+126

Step 3: add the numbers
3x= 878

Step 4: divide both sides by three
X= 878/3 or 292.6

Solve using identities

jeka57 [31]

Answer:

Solution given

Cos $\displaystyle \theta_{1}=\frac{13}{15}$

consider Pythagorean theorem

$\bold{Sin²\theta+Cos²\theta=1}$

Subtracting $Cos²\theta$ both side

$\displaystyle Sin²\theta=1-Cos²\theta$

doing square root on both side we get

$Sin\theta=\sqrt{1-Cos²\theta}$

Similarly

$Sin\theta_{1}=\sqrt{1-Cos²\theta_{1}}$

Substituting value of $Cos\theta_{1}$

we get

$Sin\theta_{1}=\sqrt{1-(\frac{-13}{15})²}$

Solving numerical

$Sin\theta_{1}=\sqrt{1-(\frac{169}{225})}$

$Sin\theta_{1}=\sqrt{\frac{56}{225}}$

$Sin\theta_{1}=\frac{\sqrt{56}}{\sqrt{225}}$

$Sin\theta_{1}=\frac{\sqrt{2*2*14}}{\sqrt{15*15}}$

$Sin\theta_{1}=\frac{2\sqrt{14}}{15}$

Since

In III quadrant sin angle is negative

<h3> $\bold{Sin\theta_{1}=-\frac{2\sqrt{14}}{15}}$ </h3>

Function form <br> 5x-7y=14

Ira Lisetskai [31]

Function form is when you put x in, you get y so the correct equaiton should be y=so and so

so

5x-7y=14
subtrac 5x form both ssides
-7y=14-5x
divide both sides by 7
-y=2-5/7x
multiply by -1
y=5/7x-2
that is it
