Answer:
x = 5 + √3, 5 - √3
which is 6.73 , 3.27 to the nearest hundredth.
Step-by-step explanation:
(x - 5)^2 = 3
Take the square root of both sides:
x - 5 = +/- √3
x = 5 + √3, 5 - √3
Generally, anyone living in your house is typically covered when driving your car, unless expressly excluded on the policy.
Permisive use also also allows you to allow your friends or family members who don’t live with you to use your car.
Permissive use means that if you give another driver permission to take your car, they will be covered by your car’s insurance coverage.
So if you allow <span>your
roommate (who doesn't have car insurance) to drive your car to run an
errand.
What will likely happen if there is a single-car accident
causing moderate damage to your car while your roommate is driving is that the insurance of your car will cover such accident.</span>
Answer:
- maximum current: 7
- time to reach maximum: 1
Step-by-step explanation:
The equation can be rewritten to vertex form to find the maximum value:
I = -5(t^2 -2t) +2 . . . . . . factor leading coefficient from variable terms
I = -5(t^2 -2t +1) +2 -(-5(1)) . . . . . add and subtract the square of half the t coefficient
I = -5(t -1)^2 +7 . . . . . . write in vertex form
The vertex of the graph is at (t, I) = (1, 7).
The maximum current of 7 is reached at t=1.
The numbers are 105 and 50
<em><u>Solution:</u></em>
Let "x" be the first number
Let "y' be the second number
Twice a number plus twice a second number is 310
Therefore,
twice of x + twice of y = 310
2x + 2y = 310 ---------- eqn 1
The difference between the numbers is 55
x - y = 55 -------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
From eqn 2,
x = 55 + y ------ eqn 3
<em><u>Substitute eqn 3 in eqn 1</u></em>
2(55 + y) + 2y = 310
110 + 2y + 2y = 310
4y = 310 - 110
4y = 200
<h3>y = 50</h3>
<em><u>Substitute y = 50 in eqn 3</u></em>
x = 55 + 50
<h3>x = 105</h3>
Thus the numbers are 105 and 50
