Angle B is 102° bc 180-78=102 and if sides DB and BC are congruent, angles D and C must also be, so you can use the original 78 and divide by 2 to get 39° for angle C

Rewrite, differentiate and simplify:<br> 3/(2x)^3

Llana [10]

$\frac{dy}{dx}$ = - $\frac{9}{8x^{4} }$

let y = $\frac{3}{(2x)^{3} }$ = $\frac{3}{8}$ $x^{-3}$

differentiate using the power rule

$\frac{d}{dx}$ ( $ax^{n}$ ) = na $x^{n-1}$

$\frac{dy}{dx}$ = - $\frac{9}{8}$ $x^{-4}$ = - $\frac{9}{8x^{4} }$

What is the image point of (6,1) after a translation left 5 units and down 1 unit?

11Alexandr11 [23.1K]

Answer:

(1, 0 )

Step-by-step explanation:

A translation of 5 units left means subtract 5 from the x- coordinate

A translation of 1 unit down means subtract 1 from the y- coordinate, thus

(6, 1 ) → (6 - 5, 1 - 1 ) → (1, 0 )

80 - [50 - {20 ÷ 2 – (16 - 2÷ 2) ÷ 3}]

trapecia [35]

Answer:

Step-by-step explanation:

We have to solve the problems in the parenthesis first.

(16-2÷2)= (16-1)=(15)

20÷2-15÷3

(20÷2)-(15÷3)

10-5=5

50-5= 45

80-45= 35

Hope this helps!
