Which graph shows y=x^2+3x-4

Ivahew [28]

Answer:

Third graph in the photo

Step-by-step explanation:

x^2+3x-4 can be factored as (x+4)(x-1). When y=0, x must be -4 or 1 to satisfy the equations, and thus the roots of the graph are at x=-4 and x=1. When x=0, y=(4)(-1)=-4. The only graph that satisfies both of these requirements is the third/last one.

densk [106]

Answer:

270 students is the highest number of students that can attend the Planetarium field trip each day

Step-by-step explanation:

Here, we want to know the highest number of students that can attend the planetarium each day

from the question;

The highest number per group is 15 students

The highest number of group is 18 groups

So the highest number of attendees will be;

15 * 18 = 270 students

Hi there,<br> I need help to solve the perimeter and the surface area of this shape.<br> Thanks!

leonid [27]

Answer: Perimeter = 6π ≈ 18.84

Area = 15π ≈ 47.10

<u>Step-by-step explanation:</u>

This is a composite of a big semicircle with diameter of 10 --> radius (r) = 5

plus a medium semicircle with diameter of 6 --> r = 3

minus a small semicircle with diameter of 4 --> r = 2

Perimeter of a semicircle = $\dfrac{1}{2}(2\pi r)=\pi r$

$P_{big}=\pi (5)\quad =5\pi\\P_{medium}=\pi (3)\quad =3\pi\\P_{small}=\pi (2)\quad =2\pi\\P_{composite} =5\pi+3\pi -2\pi\\.\qquad \qquad =\large\boxed{6\pi}$

Area of a semicircle = $\dfrac{1}{2}(\pi r^2)$

$A_{big}=\dfrac{1}{2}\pi (5)^2\quad =12.5\pi\\\\A_{medium}=\dfrac{1}{2}\pi (3)^2\quad =4.5\pi\\\\A_{small}=\dfrac{1}{2}\pi (2)^2\quad =2\pi\\\\A_{composite} =12.5\pi+4.5\pi -2\pi\\\\.\qquad \qquad =\large\boxed{15\pi}$
