Answer:

C

Step-by-step explanation:

The rate of change of a function in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b } = [ 0, 4 ]

From the graph

f(b) = f(4) = 75 and f(a) = f(0) = 15, thus

average rate of change = \frac{75-15}{4-0} = \frac{60}{4} = 15

B. Complete each inequality using <or> |-15| ○ |-5| -15 ○ -5​
ycow [4]

Answer:

|-15| > |-5|

-15 < -5​

Step-by-step explanation:

|-15| ○ |-5|

Absolute value means take the positive value

15 ○ 5

15 is greater than 5

15 > 5

-15 ○ -5​

negative 15 is less than -5

-15 < -5​

Answer for a lot of points!
earnstyle [38]

Given :

  • ZC = 90°

  • CD is the altitude to AB.

  • \angleA = 65°.

To find :

  • the angles in △CBD and △CAD if m∠A = 65°

Solution :

In Right angle △ABC,

we have,

=> ACB = 90°

=> \angleCAB = 65°.

So,

=> \angleACB + \angleCAB+\angleZCBA = 180° (By angle sum Property.)

=> 90° + 65° + \angleCBA = 180°

=> 155° +\angleCBA = 180°

=> \angleCBA = 180° - 155°

=> \angleCBA = 25°.

In △CDB,

=> CD is the altitude to AB.

So,

=> \angle CDB = 90°

=> \angleCBD = \angleCBA = 25°.

So,

=> \angleCBD + \angleDCB = 180° (Angle sum Property.)

=> 90° +25° + \angleDCB = 180°

=> 115° + \angleDCB = 180°

=> \angleDCB = 180° - 115°

=> \angleDCB = 65°.

Now, in △ADC,

=> CD is the altitude to AB.

So,

=> \angleADC = 90°

=>\angle CAD =\angle CAB = 65°.

So,

=> \angleADC + \angleCAD +\angleDCA = 180° (Angle sum Property.)

=> 90° + 65° + \angleDCA = 180°

=> 155° +\angleDCA = 180°

=> \angleDCA = 180° - 155°

=> \angleDCA = 25°

Hence, we get,

  • \angleDCA = 25°
  • \angleDCB = 65°
  • \angleCDB = 90°
  • \angleACD = 25°
  • \angleADC = 90°.

Bro i need some help and I dont wanna get the question wrong so help please??
Rzqust [24]

Answer:

see below

Step-by-step explanation:

a) 1/7 is the smallest, so a is in the correct t location.

b) is 1/3, which is larger than 1/4

c) is 2/10 or 1/5, which is smaller than 1/4

so on the graph, b and c are backwards. c should be to the right of 1/4, and b should be to the left.

Which term of the arithmetic sequence 1, 5, 9, 13, ... is 169?<br> It is the<br> th term.
sveta [45]

Answer:

43rd term

Step-by-step explanation:

Arithmetic sequences are basically linear functions, so the same value is added every time. So, knowing that Asub1 is equal to one, and Asubn is equal to 169 we can take 169-1 and divide by our common difference. This is four as 5-1=4 and 9-5=4.

So, (169-1)/4=42.

This is however 42 terms after Asub1, so this would be the 43rd teen of the sequence!
