Figure B is a line segment because it stops on both ends.

Figure C is a line because it has arrow on both ends.

Figure D is an angle, because it is 2 rays joined at a vertex.

A rectangle has a width of 5 meters and a length of 7 meters a similar rectangle has a width of 15 meters what is the length of
JulsSmile [24]
Similar rectangles have or form similar ratios. Hence to solve this, you have to get the ratio of the measurements:
Let N be the length of the similar rectangle
  5/7 = 15/N
5(N) = 7(15) -> cross multiply
  5N = 105
 5N/5 = 105/5 -> divide both sides of the equation by 5
    N = 21
Therefore, 21 meters in the length of the similar rectangle
To check - 
5/7 = 15/21 (cross multiply)
105 = 105

Approximate the area under the curve over the specified interval by using the indicated number of subintervals (or rectangles) a
devlian [24]

Answer:

The area under the function \int\limits^3_1 {9-x^2} \, dx \approx 7.25..

Step-by-step explanation:

We want to find the Riemann Sum for \int\limits^3_1 {9-x^2} \, dx with 4 sub-intervals, using right endpoints.

A Riemann Sum is a method for approximating the total area underneath a curve on a graph, otherwise known as an integral.

The Right Riemann Sum is given by:

\int_{a}^{b}f(x)dx\approx\Delta{x}\left(f(x_1)+f(x_2)+f(x_3)+...+f(x_{n-1})+f(x_{n})\right)

where \Delta{x}=\frac{b-a}{n}

From the information given we know that a = 1, b = 3, n = 4.

Therefore, \Delta{x}=\frac{3-1}{4}=\frac{1}{2}

We need to divide the interval [1, 3] into 4 sub-intervals of length \Delta{x}=\frac{1}{2}:

\left[1, \frac{3}{2}\right], \left[\frac{3}{2}, 2\right], \left[2, \frac{5}{2}\right], \left[\frac{5}{2}, 3\right]

Now, we just evaluate the function at the right endpoints:

f\left(x_{1}\right)=f\left(\frac{3}{2}\right)=\frac{27}{4}=6.75

f\left(x_{2}\right)=f\left(2\right)=5=5

f\left(x_{3}\right)=f\left(\frac{5}{2}\right)=\frac{11}{4}=2.75

f\left(x_{4}\right)=f(b)=f\left(3\right)=0=0

Next, we use the Right Riemann Sum formula

\int\limits^3_1 {9-x^2} \, dx \approx \frac{1}{2}(6.75+5+2.75+0)=7.25

Eva8 [605]

Answer:

There are many conclusions we can come to for this!

70% of the flips were heads, and 30% are tails

28/40 was heads, and 12/40 were tails

There were more heads than tails

There were 14 more heads than tails

:)
