Answer:

b = square root of 125

Put into calculator and put to 1dp

Step-by-step explanation:

Pythagorean theorem is

a^2 + b^2 = c^2

The a and b are the two short sides and c is always the hypotenuse

We just put the numbers in

10^2 + b^2 = 15^2

Now we can rearrange so that b^2 is by its self on the left side

b^2 = 15^2 - 10^2

Now just solve by putting into calculator

b^2 = 125

And finally square root to get b^2 down to b

b = square root of 125

Put into calculator and put to 1dp

Answer: b= 11.2

10^2 + b^2 = 15^2

100 + b^2 = 225

b^2 = 125

b= $\sqrt{125}$

b= 11.2

Graph y=-2x. give the domain and range. is the function dicrete or continou?

r-ruslan [8.4K]

Answer:

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

Step-by-step explanation:

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

The selling price of an item is $ 440 After 6 months of not selling, it is marked down by 30%. After another 6 months of not

liq [111]

440...marked down by 30% means u pay 70%
70% of 440 = 0.70(440) = 308

308 ..marked down by 10% means u pay 90%
90% of 308 = 0.90(308) = 277.20 <== price after markdowns

Use the quadratic formula to solve x^2-4x+3. Show your work. Then describe the solution

mars1129 [50]

Quadratic formula is x=(-b+-sqrt(b^2-4ac))/(2a)

a= 1, b=-4, and c=3

Therefore, x=(-(-4)+-sqrt((-4)^2-4(1)(3))/(2(1))

Solve for both the plus and minus equations; the answers will be the roots to the quadratic equation.
