Write an equation of a line that passes through the point (4,3) and is perpendicular to the graph of the equation y=−13x+4.
lilavasa [31]

Answer:

y = -13x + 55

Step-by-step explanation:

perpendicular formula : m1 × m2 = -1

y = -13x + 4

now we take the grafient of the equation which is 13 :

m × 13 = -1

m = -13

so now we hv a new gradient then we can find the equation use the formula y = mx + c :

m = -13 point = ( 4 , 3 )

sub them into the formula,

3 = -13 (4) + c

3 = -52 + c

3 + 52 = c

55 = c

c = 55

now we rewrite again the c and the m to become a complete equation : y = -13x + 55

How much money has to be invested at 2.3% interest compounded continuously to have $41,000 after 17 years?
Llana [10]
For this, we have to calculate how much money has to be invested at 2.3% interest compounded continuously to achieve $41,000 after 17 years

Formula: A= P * ( 1+r)^t
A= $41,000
r=0.023
t= 17
<span>41,000= P * (1+0.023)^17
</span>41,000= P * (1.023)^17
41,000= P * 1.4719
P= 41,000 : 1.4719
P= $27,731.59
Therefore, the answer is C. $27,731.59 
I checked by doing the opposite, and I got $41,000.01, which is the closest to the question<span>

Work Out<br> 8^1/3 ÷ 5^-2
svp [43]
I believe the answer would be 50

explanation:

calculate
2 ÷ 5^-2

use negative power rule x^-a = 1/x^a
2 ÷ 1/5^2

simply 5^2 to 25
2 ÷ 1/25

use this rule a ÷ b/c = a • c/b
2 • 25

simplify

Solve. −3.5=−4.6x−5.1 Enter your answer as a fraction in simplest form in the box.
Law Incorporation [45]

Answer:

<u>x = 8/23</u>

Step-by-step explanation:

<u>Adding 3.5 to each side</u>

  • -3.5 + 3.5 = -4.6x - 5.1 + 3.5
  • -4.6x - 1.6 = 0

<u>Adding 4.6x to each side</u>

  • -4.6x - 1.6 + 4.6x = 0 + 4.6x
  • 4.6x = -1.6

<u>Dividing each side by 4.6</u>

  • 4.6x/4.6 = -1.6/4.6
  • <u>x = 8/23</u>
