Answer:
I wont tell you the answer but I can tell you how to solve this one.
Step-by-step explanation:
If they are both squared then square them. Once you have the hypotenuse and the leg squared subtract the leg from the hypotenuse. That's your answer. Then you un- square it by finding the square root of the new number. That square root is your answer
The answer is $1,026.
Solving: Use Simple interest formula, I=Prt.
Make the rate into a decimal (1.6% -> 0.016)
plug in the numbers into the formula. 950 x 0.016 x 5 = 76$.
76$ will be our interest, now to find the balance we would have to add the the starting money (950) with our interest (76$), resulting in our answer of $1,026 after 5 years.
Since this is not a rational function (with undetermined values in the denominator), but just a normal expression, we can just substitute t with the value toward which the function is approaching. Since this is a continuous function, it doesn't matter from which side it's approaching 0. In this case, let t=0, then sin(4t)=0, cos(4t)=1, then -2 sin^2(4t)+2tcos(4t)=0.
30% of 90 <em>whenever it says "of" put in a multiplication sign </em>
30% x 90 <em> take out the % sign (percent means divided by 100)</em>
30/100 =3/10 <em>simplify,then multiply by 90</em>
3/10 x 90 = 270/10 <em> simplify</em>
270 = 27
90 - 27 = 63 <em>subtract 27 because it is the amount read so far from the total</em>
Keisha has to read 63 more minutes to reach her goal.
The answer would be 2x-8=3x-5 not sure though so double check
