Answer 1
Answer:

Answer:

79

Step-by-step explanation:

Since the triangles are similar, the sides that are the same length have angles that are the same size at the top.
Answer 2
Answer: Congruent triangles always have at least 3 identical elements — like if both have a right angle, a 30° angle and a 12cm side.

We are given that these two are congruent in the text. We have two identical elements so far — angle of 35 and the side opposite the angle of 35 (which is what the little line in the middle means) — but we are missing that angle G.

Since angle G in the second triangle is in the same place as the angle of 79 in the first one (between the side with the line in it and the angle of 35), we know that angle will be also 79, given that the triangles are congruent (or identical, in other words). So your answer is 79°.

D) two quadratic graphs opening up. They intersect at 0, negative 4.

Answers

Answer:

  C)  Two intercepting parabolas are shown, one facing downward and one facing upward. The downward facing parabola has a maximum at (0,1) and intercepts the x axis at 1 and negative 1. The upward facing parabola has a minimum at (0,-4) and intercepts the x axis at 2 and negative 2

Step-by-step explanation:

As shown in the attached, the graph of y = -x² +1 has its vertex at (0, 1) and opens downward. It crosses the x-axis at ±1. The graph of y = x² -4 has its vertex at (0, -4), opens upward, and crosses the x-axis at ±2. The description of this graph matches choice C.

Use the table to write and solve an equation to and the number of points p you need to score in the fourth game so that the mean number of points is 20.The table is shown below

Game|Points
1 | 25
2 | 15
3 | 18
4 | p

Answers

Answer:

The values of p is:

                   p=22

Step-by-step explanation:

We know that mean of a data set is the average of all the data values i.e. it is the ratio of the sum of all the data points to the total number of data points.

Here the table is given as:

Game |  Points

      1    |   25

      2   |    15

      3   |    18

      4   |     p

Also, it is given that:

The mean number of points is 20.

i.e.

(25+15+18+p)/(4)=20\n\ni.e.\n\n(58+p)/(4)=20\n\n58+p=20* 4\n\n58+p=80\n\np=80-58\n\np=22
(25 + 15 + 18 + p) / 4 = 20
(58 + p) / 4 = 20
58 + p = 20 * 4
58 + p = 80
p = 80 - 58
p = 22....he would have to score 22 on the 4th game for the mean of the points to be 20

How do I factor 5x^2 + 28x + 32 ?

Answers

Factor:

5x^2 + 28x + 32  =======>  Solution:  ======>   ( x   +   4 ) ( 5x   +   8 )


Steps:  Factor

5x^2 + 28x + 32

Break the expressions into groups:

( 5x^2     +    20x )      +     ( 8x       +     32 )

Factor Out   5x^2   From  5x^2   +   20x   ======>     5x( x   +   4 )

Factor Out the  8   From    8x    +   32    ========>    8 ( x      +    4 )

=       5x (x     +    4 )       +     8 ( x      +     4 )

Factor Out Common term:

x     +        4

Answer =====>  Factor of;  ==>  5x^2 + 28x + 32     ( x      +    4 ) ( 5x      +   8 )



Hope that helps!!!!                                              : )

   
Hi! First, you want to work out your exponets. We have a 5x to the 2nd power (5x^2). Look at it as 5x•5x, “• means to multiply” so that will equal 25x. Next, put it back in the equation. That’ll be 25x+28x+32. Next step is to combine variables . The variables are 25x and 28x. this will equal, 53x. Put that back into the equation, which will now be 53x+32. This will be your answer since you cannot combine those two! Hope this works!

Answers

Answer: 81.85 km/hr

Converting m/sec into km/hr, 25 m/sec = 90 km/hr

Average =

Time = 50/90  =  5/9 hr

next 120 km at an average speed of 80km/h

=> Time = 120/80  = 3/2  hr

last part of its journey at an average speed of 90km/h in 35 Minutes

time = 35 minutes = 35/60 hr = 7/12 hr

Distance covered = 90 * 7 /12  = 105/2  km

Total Distance = 50 + 120  + 105/2  = 435/2 km

Total time = 5/9 + 3/2 + 7/12   =  ( 20 + 54 + 21) /36  = 95/36

Average speed =   (435/2)/(95 /36)  = 432 * 18  /95 = 81.85 km/hr
