Answer:
y = (-4/3)x + 4
Step-by-step explanation:
Let y = mx + b, be the equation of the line in slope intercept form where we need to find m and b.
Perpendicular to y = (3/4)x - 5, means that m = - (1 / (3/4) ) = - 4/3
So, at this point, y = (-4/3)x + b.
Crossing the x - axis at 3 means that (3, 0) is a point on the line, where we note that x=3 and y=0.
Thus, we plug in these values into the equation y = (-4/3)x + b, to get
0 = (-4/3)(3) + b
0 = -4 + b, so that
b = 4.
Hence, the answer is:
y = (-4/3)x + 4
Answer: 14.29%
Step-by-step explanation:
Let C be the cost of 1 article and S the selling price for 1 article. The profit, P, for 1 article would be:
P = S - C
For n articles, the total profit would be
nP = nS - nC
Profit percentage would be (P/S)*100%
---------------------------------------------------------
We know that 21C = 18S: This can be written as C = (18/21)S
P = S - C
P = S - (18/21)S
P = (3/21)S or P=(1/7)S
Profit percentage would therefore be
(P/S)*100%
((1/7)S/S)*100%
(1/7)*100%
= 14.29%
Answer:
Step-by-step explanation:
In this problem, we are given expression in exponent form and we have to simplify the expression.
The expression is ![[4(5^{3} )]^{\frac{1}{2} }](https://tex.z-dn.net/?f=%5B4%285%5E%7B3%7D%20%29%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D)
Now, we know that 
So, 
Now, 500 can be written as 100 × 5 = 10² × 5
Therefore, ![[4(5^{3} )]^{\frac{1}{2} } = (500)^{\frac{1}{2} } = 10\sqrt{5}](https://tex.z-dn.net/?f=%5B4%285%5E%7B3%7D%20%29%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%20%3D%20%28500%29%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%20%3D%2010%5Csqrt%7B5%7D%20)
{Since 500 = 100 × 5 = 10² × 5} (Answer)
