Answer:
[tex] \frac{63}{65} [/tex]
Step-by-step explanation:
We have to find the value of sinB & cosA . So to find the value of sinB , let's use the identity
[tex] { \sin }^{2} b + { \cos }^{2} b = 1[/tex]
By using the identity above gives
[tex] { \sin}^{2} b + ( { \frac{5 }{13} })^{2} = 1[/tex]
[tex] = > { \sin}^{2} b = 1 - \frac{25}{169} = \frac{144}{169} [/tex]
[tex] = > \sin(b) = \sqrt{ \frac{144}{169} } = \frac{12}{13} [/tex]
Now to find the value of cosA , we'll use the same identity.
[tex] {( \frac{3}{5} })^{2} + { \cos}^{2} a = 1[/tex]
[tex] = > { \cos }^{2} a = 1 - \frac{9}{25} = \frac{16}{25} [/tex]
[tex] = > \cos(a) = \sqrt{ \frac{16}{25} } = \frac{4}{5} [/tex]
Now we know that
[tex] \sin(a + b)=\sin(a)\cos(b)+\sin(b) \cos(a) [/tex]
So value of sin(a+b) =
[tex] \frac{3}{5} \times \frac{5}{13} + \frac{12}{13} \times \frac{4}{5} [/tex]
[tex] = \frac{3}{13} + \frac{48}{65} [/tex]
[tex] = \frac{63}{65} [/tex]
4. The perimeters of the rectangle and the triangle below are equal. Find the value of x.
Answer:
x=6
Step-by-step explanation:
the perimeter of the rectangle is equal to 2x + 16.
the perimeter of the triangle is equal to 3x + 10.
since they are equal now you can solve by saying 2x + 16 = 3x + 10
Now you solve for x
2x + 16 = 3x + 10
2x + 6 = 3x
6 = x

End behavior is when the graph goes left or right, does it go up or down.
In this graph, when it goes left it goes up, and when the graph goes right it goes down
as x => - infinity, f(x) => Infinity
as x => Infinity, f(x) => - infinity
The leading coefficient is negative.
The degree is even.

7. The path of a baseball after it has been hit is modeled by the function h = -0.0032d? + d + 3, where his
the height in feet of the baseball and d is the distance in feet the baseball is from home plate. Find the average
rate of change for the baseball between d = 100 and d = 200.
Answer:
[tex]A = 0.04[/tex]
Step-by-step explanation:
Given
[tex]h(d) = -0.0032d^2 + d + 3[/tex]
Required
Determine the average rate of change for d = 100 to 200
Average rate of change (A) is calculated as follows:
[tex]A = \frac{h(b) - h(a)}{b - a}[/tex]
In this case:
[tex]b = 200[/tex] and [tex]a = 100[/tex]
So: [tex]A = \frac{h(b) - h(a)}{b - a}[/tex] becomes
[tex]A = \frac{h(200) - h(100}{200 - 100}[/tex]
[tex]A = \frac{h(200) - h(100)}{100}[/tex]
Solving h(200)
[tex]h(d) = -0.0032d^2 + d + 3[/tex]
[tex]h(200) = -0.0032*200^2 + 200 + 3[/tex]
[tex]h(200) = 75[/tex]
Solving h(100)
[tex]h(d) = -0.0032d^2 + d + 3[/tex]
[tex]h(100) = -0.0032*100^2 + 100 + 3[/tex]
[tex]h(100) = 71[/tex]
So: [tex]A = \frac{h(200) - h(100)}{100}[/tex] becomes
[tex]A = \frac{75 - 71}{100}[/tex]
[tex]A = \frac{4}{100}[/tex]
[tex]A = 0.04[/tex]
Hence, the average rate of change is 0.04

Jayla’s goal is to write a 100 page book of poetry. She has already written 30 pages. Each day she writes 10 more pages. How many days will it take her to finish the book?
Answer:
100
Step-by-step explanation:
100-30=70
70÷10=7
7 days or 1 week
if it is not right please let me know
Answer:
7 days
Step-by-step explanation:
100 - 30 = 70
This means that she still needs to write 70 pages.
70/10 = 7
how to graph y=-8/3x+9
Step-by-step explanation:
this is the equation for a line in slope-intercept form
the y-intercept is 9, so find (0,9) on the graph
then, the slope is -8/3 (think "rise" over "run"), so from the point (0,9) you have to count down 8 (for -8) and then to the right 3 (for +3). from this point, you can now repeat the pattern of counting down 8 and right 3 and making points to connect.
when at least two points are connected, you have a line and that is your graph
Help me please, which postulate proves these two triangles are congruent?
Answer:
C
Step-by-step explanation:
These triangles do look congruent. However, in fact, we don’t have enough information. We need 3 parts of a trainable to be shown congruent for it to be congruent, including HL congruence (because this requires a right angle). In the diagram, only 2 sides are shown to be congruent. This isn’t enough information to prove that the triangles are congruent. Therefore, it is C.
I hope this helps! :)

graph the image of triangle PQR after a reflection across the line y = 2
Answer: Refer to the diagram below
P ' is at (-7, 9)Q ' is at (1, 9)R ' is at (-6, 4)================================================
Explanation:
The diagram shows how point R moves to R'. We move up 2 units going from R(-6,0) to (-6,2). This lands us on the line of reflection. Then we move another 2 units up to land on (-6,4) which is the location of point R'.
The other points P and Q follow the same idea. Though the distances will be different from R. For P and Q, we'll move 7 units up to arrive at the line of reflection, then another 7 units to arrive at the proper locations of P' and Q', which are (-7,9) and (1,9) respectively.
Answer:
If we draw the line of y=2 and if we find the reflections we have the new points of...
R(-6,4)Q(1,9)P(-7,9)Now all we have to do it plot these points, and then we have the triangle PQR
