If a line is perpendicular to another line, it has an opposite reciprocal slope. The opposite reciprocal of -4/5 is 5/4.

Based on the picture I drew, the y intercept is (0,3), so the equation should be y = 5/4 + 3.

Answer:

y = 5/4 x + 8


Step-by-step explanation:

y= - 4/5x + 3

Slope = -4/5

Perpendicular slope = 5/4


Point (4, 13)

13 = 5/4 (4) + b

13 = 5 + b

b = 8


y = 5/4 x + 8

Anna purchased a house for $416,000 and obtained a mortgage for $394,000. She purchased 4 discount points and 5 origination poin
mrs_skeptik [129]
Cost of discount/origination points = 1% of the mortgage*number of  pints in question.

In the current scenario:
Mortgage taken = $394,000
Discount points = 4
Origination points = 5

Then,
Cost of discount points = 0.01*394,000*4 = $15,760
Cost of origination points = 0.01*394,000*5 = $19,700

I don't understand the bottom with 1/2= and 0.48=! It says find the corresponding equivalent for either the decimal or fraction
zepelin [54]
So basically, you have to find the decimal that equals 1/2 and the fraction that equals 0.48, but it has to be in simplest form. If you divide 1 by 2, you get 0.5, which would be the answer to 1/2=. For 0.48=, you would start by putting 48 over 100 because if you read the decimal aloud, it is 48 hundredths and 0.48 goes to the hundredths place. Then, you would begin to simplify 48/100. A common divisor for those 2 numbers is 2, but you could also use 4. I am going to use 4, so 48/100=12/25. Now that you have the fraction 12/25, look to see if there are any common factors. There are none, so 0.48=12/25. 
Hope this helps!! :)

an isosceles triangle has a vertex angle of 21.21 degrees. two sides of the triangle are each 17.91 ft long. whats the area of t
lubasha [3.4K]

Answer:

The area of triangle is A=58.02\ ft^{2}

Step-by-step explanation:

Let

B -----> the measure of the vertex angle of the isosceles triangle ABC

a and c -----> the two congruent sides of the isosceles triangle ABC

we know that

The area of a triangle applying the law of sines is equal to

A=\frac{1}{2}(a)(c)sin(B)

we have

a=c=17.91\ ft

B=21.21\°

substitute in the formula

A=\frac{1}{2}(17.91)(17.91)sin(21.21\°)

A=58.02\ ft^{2}
