Answer:

3m 6cm or 306cm

Step-by-step explanation:

50+6= 56

50+50= 100= 1m

2m+1m= 3m

3m+6cm= 3m 6cm

Answer:

100cm = 1m so 2m 50cm = 250cm + 56cm= 306cm which means the answer is 3m 6 cm

(b) Find the angle between u and v to the nearest degree.
yulyashka [42]

<u>Question 1 (b)</u>

<u />u \cdot v=11\\\\|u|=\sqrt{3^{2}+(-1)^{2}}=\sqrt{10}\\\\|v|=\sqrt{4^{2}+1^{2}}=\sqrt{17}

So,

\cos \theta=\frac{11}{\sqrt{10}\sqrt{17}}\\\\\theta=\cos^{-1} \left(\frac{11}{\sqrt{10}\sqrt{17}} \right) \approx \boxed{32^{\circ}}

<u>Question 2 (b)</u>

<u />u \cdot v=22\\\\|u|=\sqrt{5^{2}+2^{2}}=\sqrt{29}\\\\|v|=\sqrt{4^{2}+1^{2}}=\sqrt{17}

So,

\cos \theta=\frac{22}{\sqrt{29}\sqrt{17}}\\\\\theta=\cos^{-1} \left(\frac{22}{\sqrt{29}\sqrt{17}} \right) \approx \boxed{8^{\circ}}

Find the measure of ∠A, round to the nearest tenth.
Marina CMI [18]
I think is 70 because you first sum 18 + 6, then your answer is 24 and you subtract 90 - 24 because the triangle is a right angle that is 90 degrees. That got me 66 and I round it to the nearest tenth and I get 70.

Can someone solve this for me with their explanation please?
Lana71 [14]

First you want to subtract 36

so it looks like this \sqrt[4] {(4x+164)^3}=64

Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)

{(4x+164)^3}=64^4 which is equal to {(4x+164)^3}=16777216

Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]

Then you end up with the equation 4x+164=256

Then subtract 164 to both sides

4x=92

then divide 92 by 4

Then you get x=23

Answer:

Yes

Step-by-step explanation:

The domain is {-19, 19}

The range is {0,16}

We can write as ordered pairs to obtain:

(-19,0), (19,16)

None of the first coordinates of the ordered pairs repeats.

Hence the relation represents a function.

See attachment for mapping diagram.
