You would do 7x4 wich will equal 28

to find the area of a rectangle you need to use this formula:

area = bh base x height

4 x 7 = 28 feet.

Match the equation with its graph y 3/4x- 2

This should be the right answer though. If you go to desmos.com and type in the equations it gives you the answer.

Hope that helps :)

F(x)=-9x^2-7x+8, x=5

VashaNatasha [74]

F(x) = -9x^2 - 7x + 8
f(5) = -9(5^2) - 7(5) + 8
f(5) = -9(25) - 35 + 8
f(5) = - 225 - 35 + 8
f(50 = - 252 <==

Describe the region enclosed by the circle x^2 +y^2 = 11x in polar coordinates.

vivado [14]

Answer:

the region of the circle in polar coordinate can be expressed as:

$\mathbf{- \dfrac{\pi}{2} \leq \theta \leq \dfrac{\pi}{2} , 0 \leq r \leq 11 cos \theta}$

Step-by-step explanation:

Given that:

$x^2 +y^2 = 11x$

This implies that :

$(x-5.5)^2 + y^2 = 5.5^2$

center (5.5, 0) and radius = 5.5

The relation between the cartesian coordinates (x,y) and the polar coordinates (r, θ) is as follows:

x = rcosθ

y = rsinθ

Thus, $x^2 + y^2 = r^2$

$x^2 + y^2 = 11x$

$(rcos \theta)^2 + (r sin \theta)^2 = 11(rcos \theta)$

$r^2 = 11r cos \theta$

Thus, the angle θ runs between $- \dfrac{\pi}{2}$ to $\dfrac{\pi}{2}$

Therefore, the region of the circle in polar coordinate can be expressed as:

$\mathbf{- \dfrac{\pi}{2} \leq \theta \leq \dfrac{\pi}{2} , 0 \leq r \leq 11 cos \theta}$

The number of typing errors made by a typist has a Poisson distribution with an average of five errors per page. If more than fi

xeze [42]

Answer:

0.61596

Step-by-step explanation:

Given that:

λ = 5 (5 errors per page)

Poisson distribution formula :

P(x = x) = (λ^x * e^-λ) / x!

Probability that page does not need to be retyped means that error on page is less than or equal to 5

P(x ≤ 5) = p(x = 5) + p(x = 4) +... + p(x = 0)

The individual probabilities can be obtained using the formula above or the use of a calculator

P(x ≤ 5) = 0.17547 + 0.17547 + 0.14037 + 0.08422 + 0.03369 + 0.00674

P(x ≤ 5) = 0.61596
