Answer:
$11,714
Step-by-step explanation:
C(x) = 0.7x² - 462x + 87,944
this is a quadratic equation that opens up
the vertex will be the minimum
From the quadratic formula the x coordinate of the vertex is
x = -b/2a
x = 462/(2 * 0.7)
x = 330
Plug in
c(330) = 0.7(330²) - 462(330) + 87,944
c(330) = 11,714
$11,714
Answer:5 there is no and
6 is not definite
7 yes
Step-by-step explanation:in 6 they can't multiply
7 they are lnverses
Option D:
Right triangle
Solution:
Let us first define obtuse, acute right triangle and supplementary.
<u>Obtuse angled triangle:</u>
If any one of the angle in the triangle is more than 90°, then the triangle is an obtuse angled triangle.
<u>Acute angled triangle:</u>
If all the angles of the triangle are less than 90°, then the triangle is an acute angled triangle.
<u>Right angled triangle:</u>
If any one of the angle in the triangle is exactly 90°, then the triangle is a right angled triangle.
<u>Supplementary:</u>
If sum of the angles is 180°, then the angles are supplementary angles.
But this is not a kind of triangle.
In given triangle one of the angle is 90°.
Therefore, this is a kind of right triangle.
Option D is the correct answer.
Answer:
A. -4 and 4
B. No solution.
Step-by-step explanation:
The given equation is
A.
Equate the denominators equal to 0 to find the restrictions on the variable.
Therefore, 
.
B.
We have,
Multiply both sides by (x-4)(x+4).
Add 4 on both sides.
Divide both sides by 5.
Here the solution is x=4 but it is the restricted value.
Therefore, the given equation has no solution.
