Answer:
The discriminant of the quadratic equation is 0
Step-by-step explanation:
Here, we want to calculate the discriminant of the given quadratic equation
Mathematically, we have the discriminant calculated by the following formula;
D = b^2 - 4ac
where;
b represents the coefficient of x which is -2
a is the coefficient of x^2 which is 1/7
c is the last number which is 7
Substituting these values;
D = (-2)^2 -4(1/7)(7)
D = 4 - 4
D = 0
Answer:
≈109.5
Step-by-step explanation:
9526 divided by 87 =109.494253
Answer:
$191
Step-by-step explanation:
Find how much she will be paying over the 24 months:
34(24)
= 816
Add the down payment to this:
816 + 70
= 886
Find the difference between this and 695:
886 - 695
= 191
So, the difference will be $191 more
Step 1) Divide the figure into separate shapes
Large rectangle: 8 x 9
Medium rectangle: 4 x 6
Quarter circle: r = 3
Step 2) Find the area of each shape
Large rectangle: A = 8 x 9 = 72
Medium rectangle: A = 4 x 6 = 24
Quarter circle: A = 1/4 x 3.14 x 3^2 = 7.065 + 3 = 10.065
Step 3) Add the areas together
A = 72 + 24 + 10.065 = 106.065 square millimeters (may need to round to 106.07, but rounding not given in the problem)
Hope this helps! :)
If its talking about the temperature decreased it would be -11 but it's asking for an integer
