Answer:

(-3.08,0).

Step-by-step explanation:

We have been given that one of the x-intercepts of the parabola y=3x^2+6x-10 is approximately (1.08, 0). We are asked to find the another x-intercept of parabola.

We will use quadratic formula to solve our given problem.

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

Upon substituting our given values in above formula we will get,

x=\frac{-6\pm \sqrt{6^2-4*3*-10}}{2*3}

x=\frac{-6\pm \sqrt{36+120}}{6}  

x=\frac{-6\pm \sqrt{156}}{6}    

x=\frac{-6+\sqrt{156}}{6}\text{ or }x=\frac{-6-\sqrt{156}}{6}

x=-1+2.081665999466\text{ or }x=-1-2.081665999466

x=1.081665999466\text{ or }x=-3.081665999466

x\approx 1.08\text{ or }x\approx -3.08

Therefore, the other x-intercept of the parabola is approximately (-3.08,0).

3x^2 + 6x - 10 = 0

x  = [-6 +/- sqrt(^2 - 3*3*-10)] / 2*3

=  1.08 and -3.08

Other x -intercept is (-3.08,0)

Black_prince [1.1K]

An appropriate cautious reading of a receipt entail making sure that the

items charged are the same as the items received and checking to see if all

of the discounts were applied properly,

When an item is bought, a receipt is usually issued which confirms that

payment has been made for the goods or services. Receipt however should

be properly checked to detect any error in the course of the transaction.

Making sure that the items charged are the same as the items received and

to avoid shortages of the resources of the parties involved.

Write an explicit formula for an,<br> the nth<br> term of the sequence 31, 37,43, ....
Alchen [17]

Answer:

The formula for the nth term of this sequence is: 31 + (n-1)X6

Step-by-step explanation:

This is an arithmetic sequence (ie. each term is the last term with a fixed value added to it).

T1 =31

T2 = 37 = T1 + 6 = 31 + 6

T3 = 43 = T2 + 6 = 31 + 6 + 6 = 31 + 6X2

…

In general, the nth term is 31 + 6(n-1)

beni is shopping for a new cell phone plan. company a charges$72.25for a new phone and $85.50 per month.company b charges $151.2
tigry1 [53]
Missing questions and subsequent solutions:
(a) Write an equation for company A for cost, C, number of months, n, that Beni will pay for the phone.

Solution:
For company A:
C = 72.25 + 85.50n

(b) Write an eqyation for company B for cost, C, and number of months, n, that Bei will pay for the phone.

Solution:
For company B:
C = 151.25 + 65.75n

(c) Write an inequality when the cost from company A is better than cost from company B.

Solution:
72.25 + 85.50n ≤ 151.25 + 65.75n
(85.50-65.75)n ≤ (151.25 - 72.25)
19.75 n ≤ 79
n ≤ 4

(d) Value of n for which cost from the two companies will be the same.

Solution:
If cost for companies A and B are the same, then
72.25 + 85.50n = 151.25 + 65.75n
(85.5 - 65.75)n = 151.25 - 72.25
19.75n = 79
 n = 79/19.75 = 4 months

After 4 months,
C = 72.25 + 85.5*4 = $414.25
