Find the standard form of the equation of the parabola with a focus at (-4, 0) and a directrix at x = 4.
<span>x/9 = 8/36 </span>
<span>x = 9 * 8/36 [multiplying each side by 9] </span>
<span>x = 2 </span>
<span> </span>
<span>x/90 = 4.4/12 </span>
<span>x = 90 * 4.4/12 [multiplying each side by 90] </span>
<span>x = 33 </span>
<span>Both proportions should be expressed as lemon juice to water, or water to lemon juice. Either way would give a correct answer: </span>
<span>2/7 = j/28 [lemon juice to water] </span>
<span>8 = j [multiplying each side by 28] </span>
<span>7/2 = 28/j [water to lemon juice] </span>
<span>7j = 56 [multiplying each side by 2j] </span>
<span>j = 8 [dividing each side by 7] </span>
<span>The length proportion is 24 in to 32 ft. </span>
<span>The actual house is 24 ft tall. </span>
<span>Let x represent the doll house height, in inches. Then </span>
<span>x/24 = 24/32 </span>
<span>x = 24 * 24/32 = 18 inches</span>
Answer:
Step-by-step explanation:
x=1
There should be a point the line is going through, (1,2).
We have given that,
N55.60 for 1yr 6 months at the rate of 2%
We have to determine the principal which will yield simple interest of N55.60 for 1yr 6 months at the rate of 2%.
<h3>
What is the simple interest?</h3>
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
x = inches
y = miles
per 1 inch = 2 miles
so on the graph, there should be a point the line is going through, (1,2).
