The coordinate points of triangle ABC are A(5,0), B(2,1), and C(-4,-4). If the triangle is translated 8 units right and 5 units

Studentka2010 [4]

Answer:

A(13,-5)

B(10,-4)

C(4,-9)

Step-by-step explanation:

Translation of 8 units right >>> affects the "x" coordinate. Add 8 to each x coordinate.

Translation of 5 units down >>> affects the "y" coordinate. Subtract 5 from each y coordinate.

The coordinates are:

A (5,0)

B (2,1)

C (-4,-4)

New coordinates would be:

A (5+8,0-5)

B(2+8,1-5)

C(-4+8,-4-5)

Hence,

A(13,-5)

B(10,-4)

C(4,-9)

These are the new coordinates after the translation given.

A length of tape is 135 centimetres long. It is cut into two pieces. The first piece is twice

Annette [7]

Answer:

Step-by-step explanation:

let the longer tape be x

shorter tape be y

given

x+y=135⇒equation 1

also given

2y=x⇒equation 2

subtituting eq2 in eq1

2y+y=135

3y=135

y=135/3=45

hope this helps

Which function described below has the greatest rate of change? I WILL MARK BRAINLIEST

Ymorist [56]

Answer:

C III

Step-by-step explanation:

The rate of change of a linear function is the slope.

f(x) = mx + b is the equation of a linear function whose graph is a straight line. m is the slope.

I f(x) = 4x - 3; m = slope = 4

II f(x) = 1/2 x + 5; m = slope = 1/2

III We can use two points to find the slope.

Let's use points (1, 6) and (2, 12).

m = slope = (y2 - y1)/(x2 x1) = (12 - 6)/(2 - 1) = 6/1 = 6

The three slopes are 4, 1/2, 6.

The greatest rate of change is 6, so the answer is C III.

Find the derivative using the limit process of f (x) = - 10x

zubka84 [21]

Answer:

$\frac{d}{dx} f(x) =-10$

General Formulas and Concepts:

Calculus

Derivative Notation
Definition of a Derivative: $\lim_{h \to 0} \frac{f(x+h)-f(x)}{h}$

Step-by-step explanation:

Step 1: Define

f(x) = -10x

Step 2: Find Derivative

Substitute: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10(x + h)-(-10x)}{h}$
Distribute -10: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h-(-10x)}{h}$
Distribute -1: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h+10x}{h}$
Combine like terms: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10h}{h}$
Divide: $\frac{d}{dx} f(x)= \lim_{h \to 0} -10$
Evaluate: $\frac{d}{dx} f(x)=-10$
