The registration fees for the auto were determined from California's DMV website The registration fee is $182 plus 0.65% of the
dybincka [34]

We have to find 0.65% of 182

\\ \rm\longmapsto 0.0065\times 182

\\ \rm\longmapsto 1.183\$

Now total fee

\\ \rm\longmapsto 182+1.183=183.183\$

How do I solve this problem?
Anvisha [2.4K]

Answer:

y+11=-\frac{1}{4}(x-4)

Step-by-step explanation:

since the equation is perpendicular to y=4x-2, m=-1/4 (negative reciprocal). (x_1,y_1)=(4,-11), plug all the values into the equation y- y_1 = m(x-x_1) and we get y+11=-\frac{1}{4}(x-4)

In each part, a and b represent the length of a leg of a right triangle, and c represents the length of its hypotenuse. Find the
Pie

Answer:

c=13 and a=20

Step-by-step explanation:

Here you need to use the Pythagoras theorem :

c²=a² + b²

c = √a² + b²

c = √(12)²+(5)²

c= √144+25

c = √169

c = 13

2) c²=a²+b²

    b= √c²-b²

    b= √(29)²-(21)²

    b = √400

    b = 20

In 2 you change your formula just so that it can be easier and just calculate your length straight forward but you can also just do it in the original equation
