An object with a starting velocity of 15 m/s accelerates at 3 m/s2. How far does the object travel within 10 seconds?

Anna007 [38]

Answer: 300 m

Step-by-step explanation:

$distance(s)=v_it+\dfrac{1}{2}at^2 \quad \text{where}\ v_i \text{is initial velocity, a is acceleration, t is time}$

$s=(15)(10)+\dfrac{1}{2}(3)(10)^2$

= 150 + 150

= 300

Find the remainder when

Alona [7]

Dividing f(x) by 2x + 5 leaves the same remainder as division by x + 5/2. By the remainder theorem, it is equal to f (-5/2), so the remainder here is

f (-5/2) = 8 (-5/2)³ + 4 (-5/2)² - 13 (-5/2) + 3 = -129/2

*ANSWER FAST* x-1/x-2 + x-3/x-4 = 3 1/3 [x≠2 , x≠4] find

Natali5045456 [20]

Answer:

x = 5, x = $\frac{5}{2}$

Step-by-step explanation:

Given

$\frac{x-1}{x-2}$ + $\frac{x-3}{x-4}$ = 3 $\frac{1}{3}$

$\frac{(x-1)(x-4)+(x-3)(x-2)}{(x-2)(x-4)}$ = $\frac{10}{3}$

$\frac{x^2-5x+4+x^2-5x+6}{x^2-6x+8}$ = $\frac{10}{3}$

$\frac{2x^2-10x+10}{x^2-6x+8}$ = $\frac{10}{3}$ ( cross- multiply )

10(x² - 6x + 8) = 3(2x² - 10x + 10) ← distribute both sides

10x² - 60x + 80 = 6x² - 30x + 30 ← subtract 6x² - 30x + 30 from both sides

4x² - 30x + 50 = 0 ( divide through by 2 )

2x² - 15x + 25 = 0 ← in standard form

(2x - 5)(x - 5) = 0 ← in factored form

Equate each factor to zero and solve for x

2x - 5 = 0 ⇒ 2x = 5 ⇒ x = $\frac{5}{2}$

x - 5 = 0 ⇒ x = 5
