Answer:

quadratic parent function

Step-by-step explanation:

squares cannot be negative no matter what you cannot square a number into a negative number which is why there are no negative y values because y is a function of X

Please help math finals!!!What is the equation of the line that has a slope of 14 and goes through the point (8,−3)

katovenus [111]

I'm taking the same final test.

The answer is y= 1/4x - 5

How? Well in this case we are using the formula y= mx + b

Substituting it with the given point (8, -3) and the slope 1/4

it'll look like -3 = 1/4 (8) + b

Next we solve.

-3 = 1/4 (8) + b

-3 = 8/4 + b

-3 = 2 + b

-2 -3 = b

-5 = b

so we now we know that b = -5.

All we have to do is substitute that into the equation to get our final answer (this time, without the point 8,-3).

Our answer in the end is y = 1/4x -5

What is the increase in temperature that comes with an increase of 1 cycle per second in the rotation

Alex17521 [72]

Answer:

The increase in temperature is $0.8\°C$

Step-by-step explanation:

we know that

The formula to calculate the rate or slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(11,23.8)\ B(13,25.4)$

Substitute the values

$m=\frac{25.4-23.8}{13-11}$

$m=0.8\frac{\°C}{cycle\ per\ second}$

therefore

The increase in temperature is $0.8\°C$

Two sides of a triangle measure 8 ft and 12 ft, respectively. The included angle is 65˚. Approximately how long is the third sid

Virty [35]

Answer:

Approximately 11 feet.

Step-by-step explanation:

Let the length of the third side of the triangle be represented by x. Applying Cosine rule, we have:

$c^{2}$ = $a^{2}$ + $b^{2}$ - 2abCos C

⇒ $x^{2}$ = $8^{2}$ + $12^{2}$ - 2(8 x 12) Cos $65^{o}$

= 64 + 144 - 192 x 0.42262

= 208 - 81.143

= 126.857

x = $\sqrt{126.857}$

= 11.2631

x ≅ 11

The length of the third side of the triangle is approximately 11 feet.
