Answer:

x-intercept: (4, 0), (-5, 0)

y-intercept: (0, -20)

Explanation:

x² + x - 20

x² + 5x -4x -20

x(x+ 5) -4(x +5)

(x-4)(x + 5)

Their x-intercept: (at x intercept, y will be 0)

(x-4)(x + 5) = 0

x = 4, x = -5

Their y intercept: (at y intercept, x will be 0)

y = (x-4)(x + 5)

y = (0-4)(0 + 5)

y = -20

Answer:

x-intercepts : (4, 0) and (-5, 0)
y-intercept : (0, -20)

Step-by-step explanation:

Finding x-intercept(s)

The x-intercept's y-coordinate will be 0
⇒ 0 = (x - 4)(x + 5)
⇒ x = 4 and x = -5
The x-intercepts are : (4, 0) and (-5, 0)

Finding y-intercept

The y-intercept's x-coordinate will be 0
⇒ y = 0² + 0 - 20
⇒ y = -20
The y-intercept will be (0, -20)

Use the Shell Method to find the volume of the solid obtained by rotating region under the graph of f(x)=x^2+2 for 0≤x≤5 about x

Irina18 [472]

For each x in the interval 0 ≤ x ≤ 5, the shell at that point has

• radius = 5 - x, which is the distance from x to x = 5

• height = x ² + 2

• thickness = dx

and hence contributes a volume of 2π (5 - x) (x ² + 2) dx.

Taking infinitely many of these shells and summing their volumes (i.e. integrating) gives the volume of the region:

$\displaystyle 2\pi \int_0^5 (5-x)(x^2+2)\,\mathrm dx=2\pi\int_0^5 (10-2x+5x^2-x^3)\,\mathrm dx=\boxed{\frac{925\pi}6}$

You and your friend play a game. You answer 80% of the questions correctly and your friend answers 0.60 of the questions correct

bezimeni [28]

Answer:

Step-by-step explanation:

Assuming both players can answer the same question, the minimum number of questions is the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.

Let x be the number of questions, solving by trial and error:

$if\ x=2\\x*0.8=1.6\\x*0.6=1.2\\\\if\ x=3\\x*0.8=2.4\\x*0.6=1.8\\\\if\ x=4\\x*0.8=3.2\\x*0.6=2.4\\\\if\ x=5\\x*0.8=4\\x*0.6=3\\\\$

Therefore, the minimum number of questions in the game is 5.

Jim Tree sells trees. The mean length of the trees purchased was 68 inches with a standard deviation of 10 inches. Jim wants to

Zepler [3.9K]

Step-by-step explanation:

We know that,

$Z=\dfrac{X-\mu}{\sigma}$

Where,

X = raw score = 84

μ = mean = 68

σ = standard deviation = 10

Putting the values,

$Z=\dfrac{84-68}{10}=1.6$

The percent of his sales that were less than or equal to 84 inches, is

$P(Z\leq 1.6)=0.9452=94.52\%\approx 94.5\%$

Therefore, the remaining 100-94.5=5.5% were more than 84 inches.
