4 0

Answer: 1. Peer review involves scientists openly publishing details of the methods they used, the results of

their experiments, and the reasoning behind their hypotheses for other scientists working in the

same field to evaluate. = B true .

2. Data from controlled experiments can provide evidence that one variable causes another. = B true .

Step-by-step explanation:

Peer review is when a scientist conducts an experiment and then gives all of their information and findings to peers in order for them to follow the findings and see if the first findings are rational.

The line containing the median of the trapezoid whose vertices are R(-1, 5) , S(1, 8), T(7, -2), and U(2, 0).
bearhunter [10]

Answer:

y=-\dfrac{5}{3}x+6.5

Step-by-step explanation:

Given: trapezoid RSTU with vertices R(-1, 5), S(1, 8), T(7, -2), and U(2, 0).

Plot these points on the coordinate plane. As you can see, lines RU and ST are parallel lines and segments ST and RU are bases of the trapezoid.

The median of the trapezoid (the middle line) passes through the midpoints of the sides RS and TU. Find these midpoints:

M\left(\dfrac{x_S+x_R}{2},\dfrac{y_S+y_R}{2}\right)\Rightarrow M(0,6.5)\\ \\N\left(\dfrac{x_T+x_U}{2},\dfrac{y_T+y_U}{2}\right)\Rightarrow N(4.5,-1)

The equation of the line MN is

\dfrac{x-0}{4.5-0}=\dfrac{y-6.5}{-1-6.5}\\ \\\dfrac{x}{4.5}=\dfrac{y-6.5}{-7.5}\\ \\y=-\dfrac{5}{3}x+6.5

What are the x-intercepts of y=sin(x)+1
Stella [2.4K]

Answer:

x = n\pi + ( { - 1)}^{n}  \times  \frac{3\pi}{2}

Step-by-step explanation:

We want to find the x-intercepts of

y =  \sin(x)  + 1

At x-intercept, y=0.

0 =  \sin(x)  + 1

\sin(x)  =  - 1

Take sine inverse of both sides to get:

x =  { \sin }^{ - 1} ( - 1)

x = n\pi + ( { - 1)}^{n}  { \sin }^{ - 1} (  1)

The x-intercepts are:

x = n\pi + ( { - 1)}^{n}  \times  \frac{3\pi}{2}

for n being an integer
