Answer:

Step-by-step explanation:

13) x⁴-12x² +36    

(a-b)² = a²-2ab+b²

a = x² ; b = 6

(x²)² - 2 * x² * 6 + 6² =  (x² - 6)²

14) w⁴- 14w² - 32 =     w⁴+ 2w² - 16w² - 32  = w² (w² + 2) - 16 (w²+2)

                           = (w² + 2) (w² -16 )

15) k³ + 7k² - 44k = k ( k² + 7k -44)  = k ( k+11 ) ( k-4 )

16) 2a³ +28a²+96a =2a(a²+14a+48) = 2a(a+6)(a+8)

17) -x³ +4x² +21x = (-x) ( x² - 4x - 21) = (-x)(x-7)(x+3)

18) m⁶ - 7m⁴ -18m² = m² ( m⁴-7m²-18) = m² (m²-9)(m²+9)

                             = m² (m+1) (m-1)(m²+9)

19) 9y⁶ +6y⁴ + y²= y² ( 9y⁴+6y²+1) = y² (3y²+1)²

20) 8c⁴+10c² -3 = (4c +1)(2c-3)

Radda [10]
All you need to do is 267 times 93 to get the exact answer. the questions says ABOUT how many sticks so we can round the numbers. we can turn 267 into 270 and 93 into 90 and then multiply 270 by 90 to get 24,300 popsicle sticks

The slope of the the tangent line to a curve at a point. Calc derivative help
pickupchik [31]

Answer:

y = 108x + 216

Step-by-step explanation:

given

y = 4x³ then \frac{dy}{dx} = 12x² = m_{tgt}

x = 3 ⇒ m = 12(- 3)² = 108

equation of tangent in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept ), hence

y = 108x + b

To find b substitute (- 3, - 108) into the equation

- 108 = -324 + b ⇒ b = - 108 + 324 = 216

y = 108x + 216 ← equation of tangent
