A skateboarder starting from rest accelerates down a ramp at 2 m/s for 2 s. What is the final speed of the skateboarder

Mathematics
1 answer:
Sedaia [141]3 years ago
7 0

Initial speed of the skateboard (u) = 0 m/s (Starts from rest)

Acceleration of the skateboard (a) = 2 m/s²

Time taken by the skateboard (t) = 2s

By using equation of motion, we get:

\bf \longrightarrow v = u + at \\  \\ \rm \longrightarrow v = 0 + 2 \times 2 \\  \\ \rm \longrightarrow v = 4 \: m {s}^{ - 1}

\therefore Final speed of the skateboard(v) = 4 m/s

Segments RT and SU are diameters of circle O.<br><br> What is m?<br> 258°<br> 266°<br> 274°<br> 282°
Lynna [10]

we know that

The minor arc ST is equal to the angle ∠SOT by central angle

∠SOT=∠ROU ------> by vertical angles

In this problem we have

∠ROU=94\°

substitute

∠SOT=94\°

so

minor arc ST=94\°

Find the major arc SRT

we know that

The major arc plus the minor arc is equal to 360\°

minor arc ST+major arc RST=360\°

Solve for major arc RST

major arc RST=360\°-94\°=266\°

therefore

<u>the answer is</u>

266\°

Given EFGH and E=45°, what is the measure of angle F?
Goryan [66]
Remember that opposite angles are congruent. 

So,

we know that <E= <G

That is 45+45= 90 degrees 

We also know that consecutive angles are supplementary. E and F would equal 180 degrees. 

180-45=135

<F= 135 degrees. 

We can check this by seeing if all the angles add up to 360 degrees/

135+135+45+45

=360 <== this works

I hope this helps!

The triangular pyramid shown is made up of four congruent triangles. The length of the base is 8 inches, and the height of the b
Aneli [31]

Answer:

(B) Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4 (one-half (8) (6.9))

Step-by-step explanation:

Base of the Pyramid = 8 Inches

Height of the Triangular Face = 6.9 Inches

In any solid shape, the Lateral surface area is the sum of all sides except its top and bottom bases.

Since the four triangles are congruent:

Lateral Surface Area = 4 X Area of One Triangle

Area of a Triangle = \frac{1}{2}$ X Base X Height

Area of one Triangular Face = \dfrac{1}{2}(8)(6.9)

Therefore:

Lateral Surface Area = 4\left(\dfrac{1}{2}(8)(6.9)\right)

Therefore, Talia is correct.
