Answer:

$17.14

Step-by-step explanation:

Given : y = - 0.34x^2 + 4.43x + 3.46

To Find : Using the quadratic regression equation, what was the predicted profit in year 8

Solution :

y = - 0.34x^2 + 4.43x + 3.46

Where y is profit and x is year

Substitute x = 8

y = -0.34(8)^2 + 4.43(8) + 3.46

y =17.14

So, Option D is true

Hence the predicted profit in year 8 is $17.14

. Write the following expression in factored form using the greatest common factor.<br> 50a3 + 10a2
Tanya [424]

The factors of  50a³  are  1,  2,  5,  10,  25,  50,
   and their products with a, a² and a³ .

The factors of  10a²  are  1,  2,  5,  10,
    and their products with 'a' and a² .

Their common factors are  1, 2, 5, 10,
       and their products with 'a' and a².

Their greatest common factor is  10a² .

(Another way to spot it, easily, is to remember this helpful factoid:

                 If the smaller number is a factor of the larger number,
                 then the smaller number is their greatest common factor.

Using the greatest common factor, then . . .

           50a³ + 10a²  =     10a²(5a + 1) .

4/5(2x+5)−4=1<br><br> x = 1 1/4<br> x = 1 2/5<br> x = 5/8<br> x = 3 1/5
tia_tia [17]
The answer is x=5/8. The reason for this is when you divide it equal 0.625 then when you multiply that by 2 it equals 1.25. After you do that you add 5 which is 6.25. Now we divide 4/5 which is 0.8. Now, we multiply 6.25x0.8=5. 5-4=1. Therefore your answer is 5/8. Hope this helps :)
