Each Friday, the sixth grade students in Mr. Shin's physical education class spend the first five minutes doing crunches. Instea

d of keeping track of the weekly total number of crunches, Mr. Shin keeps track of how they do compared to the week before, and then records the result as a positive or negative number. Record the number for each of the following:
Ben did 10 more crunches this week than last week. What number would Mr. Shin record?
Gail did 8 less crunches this week than last week. What number would Mr. Shin record?
Nathaniel did the same number of crunches this week as last week. What number would Mr. Shin record?

If the length of the shorter arc AB is 22 cm and C is the centre of the circle then the circumference of the circle is :​
Ahat [919]

Answer:

The circumference of the circle is 176cm

Step-by-step explanation:

Step 1.

Figure out how many of those segments would fit in a whole circle

360/45=8

Step 2.

We know that the length of AB is 22cm so we multiply that by the number of segments in a whole circle

22×8=176

Triangle A E C is shown. Line segment B D is drawn near point C to form triangle B D C.
AVprozaik [17]

∠BDC and ∠AED are right angles, is  a piece of additional information is appropriate to prove △ CEA ~ △ CDB

Triangle AEC is shown. Line segment B, D is drawn near point C to form triangle BDC.

<h3> What are Similar triangles?</h3>

Similar triangles, are those triangles which have similar properties,i.e. angles and proportionality of sides.

Image is attached below,
as shown in figure
∡ACE = ∡BCD ( common angle )
∡AED = ∡BDC ( since AE and BD are perpendicular to same line EC and make right angles as E and C)
∡EAC =- ∡DBC ( corresponding angles because AE and BD are parallel lines)

Thus, △CEA ~ △CDB , because of the two perpendiculars AE and BD.

What is the 20th term of the linear sequence?<br><br>1,7,13,19,25
Nimfa-mama [501]

Answer:

115

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 7 - 1 = 13 - 7 = 19 - 13 = 25 - 19 = 6

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = 6 , thus

a₂₀ = 1 + (19 × 6) = 1 + 114 = 115

F(x)=4x^3+3x-2 and g(x)=2x+2 what is the value of f(x)=g(x)?
Arlecino [84]

Answer:

x ≈ 0.916875

Step-by-step explanation:

→ Equate the expressions to each other

4x³ + 3x - 2 = 2x + 2

→ Get all the terms to one side

4x³ + x - 4

→ Solve for x

x ≈  0.916875
