The quadratic function y = –10x2 + 160x – 430 models a store’s daily profit (y) for selling a T-shirt priced at x dollars. What

asambeis [7]

Answer:

x = 4 or x = 12

Step-by-step explanation:

Given:

y = -10x² + 160x - 430

When y = $50

50 = -10x² + 160x - 430

50 + 430 = -10x² + 160x

480 = -10x² + 160x

-10x² + 160x - 480 = 0

Divide through by -10

x² - 16x + 48 = 0

Solve the quadratic equation using factorization method

+48 = -12 × -4

-16 = -12 -4

Therefore,

-12 and -4 are both factors

x² - 16x + 48 = 0

(x - 4 )(x - 12 ) = 0

x - 4 = 0

x = 4

x - 12 = 0

x = 12

Determine if p2+14p+49 is a perfect trinomial

shusha [124]

Answer:

Step-by-step explanation:

p² + 14p + 49 = p² + 2 * 7p + 7²

Comparing with a² + 2ab + b²,

a= p and b = 7

So 2ab = 2*p*7 = 14 p

So, p² + 14p + 49 is a perfect trinomial

Find 0,8,3 round the nearest degree

MArishka [77]

The measure of $\theta$ is 68 degrees

<h3>How to solve the angle?</h3>

The complete question is in the attached image

The value of $\theta$ is calculate using the following cosine function

$\cos(\theta) = \frac 38$

Evaluate the quotient'

$\cos(\theta) = 0.375$

Take the arc cos of both sides

$\theta = \cos^{-1}(0.375)$

Evaluate the arc cos

$\theta = 67.97$

Approximate to the nearest degree

$\theta = 68$

Hence, the measure of $\theta$ is 68 degrees
