Recall that the discriminant is b² - 4ac
So, substitute, b = 4, a = -1 and c = -2

Δ = 16 - 4(-1)(-2) = 16 - 8 = 8

Kathy Parker's employer pays 65% of the total cost of her $5,489 health insurance premium. What is her biweekly deduction for th
zzz [600]

Answer:

$73.89

Step-by-step explanation:

We have been given that Kathy Parker's employer pays 65% of the total cost of her $5,489 health insurance premium.

This means Kathy pays 35% of her health insurance premium.

Let us find 35% of $5489.

\text{Amount of health insurance premium paid by Cathy per year}=\frac{35}{100}\times\$5489

\text{Amount of health insurance premium paid by Cathy per year}=0.35\times\$5489

\text{Amount of health insurance premium paid by Cathy per year}=\$1921.15

As we are asked to find Cathy's biweekly deduction for the insurance we will divide amount of premium paid by Cathy by 26 as biweekly is paid 26 times per year.

\text{Cathy's biweekly deduction}=\frac{\$1921.15}{26}

\text{Cathy's biweekly deduction}=\$73.89

Therefore, Cathy's biweekly deduction for the insurance is $73.89.

Write the equation y=-1/2x+3 in standard form.
cricket20 [7]
Begin by multiplying both sides by 2 to get rid of the fraction.  The standard form for a line is Ax + By = C, no fractions allowed.  By multiplying we get 2y=-1x+3.  Now move the -1x over by adding and we have the standard form we are looking for: x + 2y = 3.

Can you please help me with this question ?​
mihalych1998 [28]

Answer:

It is a Cuboid

Area of the base = 12x9

Area of the top = 12x9

Area of the right lateral faces = 9x7

Area of the left lateral faces = 9x7

Area of the front face = 12x7

Area of the rear face = 12x7

Total surface area is the sum of above (please do it yourself)

The volume = base surface Area x height

= 12x9x7 = 756

Be reminded to put in the right unit for Area and volumn
