it depends what the number is
Answer:
they are all equal side so add them up
Step-by-step explanation:
Answer:
Range is [1, ∞)
Step-by-step explanation:
The values of x can be 1 up to infinity (the domain).
When x = 1 , f(x) = 1^2 = 1
when x = ∞, x^2 = ∞
So the range is [1, ∞)
Answer:
3.9%
Step-by-step explanation:
The formula for compound interest to apply is;
where;
A=amount at the end
P=starting amount/principal
n=number of compounding years
t=total number of years
r=interest rate expressed as a decimal
Given
P=$4200, n=2, t=4 and A=$4900 R=?
Substitute values in equation, take r=r
Divide both sides by 4200
Introduce root 8 to the left hand side, thus eliminating the power 8 in the right hand side
![\sqrt[8]{1.1667} =1+0.5r\\\\\\1.0195=1+0.5r\\\\\\1.0195-1=0.5r\\\\\\0.0195=0.5r\\\\\\\frac{0.0195}{0.5} =\frac{0.5r}{0.5} \\\\\\0.039=r](https://tex.z-dn.net/?f=%5Csqrt%5B8%5D%7B1.1667%7D%20%3D1%2B0.5r%5C%5C%5C%5C%5C%5C1.0195%3D1%2B0.5r%5C%5C%5C%5C%5C%5C1.0195-1%3D0.5r%5C%5C%5C%5C%5C%5C0.0195%3D0.5r%5C%5C%5C%5C%5C%5C%5Cfrac%7B0.0195%7D%7B0.5%7D%20%3D%5Cfrac%7B0.5r%7D%7B0.5%7D%20%5C%5C%5C%5C%5C%5C0.039%3Dr)
r=3.9%
The correct question is
<span>John mixed 3/4 liter of yellow paint with 1 1/4 liters of red paint to make 2 liters of orange paint. • He needed more orange paint. • To make a new batch of orange paint, he used exactly 1 liter of red paint. Using the same ratio, how many liters of yellow paint should John use to make the new batch of orange paint?
we know that
yellow paint---> 3/4 liters
red paint-----> 1 1/4 liters-----> (1*4+1)/4-----> 5/4 liters
ratio=yellow paint/red paint-----> (3/4)/(5/4)---> 3/5
if h</span>e used exactly 1 liter of red paint
<span>so
3/5=x/1------> x=3/5 liters of yellow paint
the answer is
</span>3/5 liters of yellow paint<span>
</span>
