Answer:
Step-by-step explanation:
∠X ≅∠Z : Given
∠ZYV≅∠XYU
∠ZVY≅∠XUY Because ∠ZYV≅∠XYU, ∠X ≅∠Z.
So ∠YVW≅∠YUW
Draw VU
ΔVWU is an isosceles triange so ∠UVW≅∠VUW
So ∠YVU≅∠YUV
Therefore ΔYVU is also an isosceles triangle and YV = YU
So ΔZYV≅ΔXYU ( ASA)
So XU = ZV ( because of CPCTC)
Therefore XU + WU = ZV = VW : XW = ZV
ΔXWV ≅ΔZWU ( ASA)

Step-by-step explanation:
tan²(α) (2 cos²(α) + sin²(α) - 1)
Recall that sin²(α) + cos²(α) = 1 for all α. Then sin²(α) - 1 = -cos²(α) :
tan²(α) (2 cos²(α) - cos²(α))
tan²(α) cos²(α)
Rewrite tan(α) = sin(α) / cos(α) :
(sin(α) / cos(α))² cos²(α)
(sin²(α) / cos²(α)) cos²(α)
Cancel the factors of cos²(α) :

24. Michael leaves his house at 0837 and travels by motorcycle to the railway station, which is 27 km from his
house.
(i) If he arrives at the station 36 minutes later, find the average speed at which he travels in km/h.
(ii) If the train, which is due at 0942, is 11 minutes late, how long will he have to wait?
Answers
Answer:
i) 45km/hr
ii)29 min
Step-by-step explanation:
average speed = distanced travelled / time elapsed
It took 36min and need to convert to hr
36min x [tex]\frac{hours}{60 min}[/tex] = [tex]\frac{36 hr}{60 min}[/tex] = [tex]\frac{9 }{15 }[/tex] hours
distanced travelled is 27 km;
average speed = 27km / (9/15hr) = 45 km/hr
Add 36min to 0837 becomes 0913, the train will arrive at 0942 and the wait will be the difference of 0942 - 0913 = 29 min

Answers
Answer:
inverse, 16, 4
Step-by-step explanation:
The constant of variation when eight apps are running, battery lasts for 4 hours is 32.
What is Inverse Variation?When a variable varies inversely with the other variable, i.e. on increasing one variable the other decreases is called Inverse Variation.
The battery life varies inversely with the number of apps running
The battery life is denoted by b
and the number of apps is denoted by a
then
[tex]\rm b\; \alpha \; (1/a)\\\\b = k /a[/tex]
here k is the proportionality constant
The battery lasts for 16 hours when the apps opened is 1
The battery lasts for 4 hours when the apps opened is 4
16 = k
The constant of variation when eight apps are running, battery will last for 4 hours
[tex]\rm 4 = k /8[/tex]
k = 32

Volume of cylinder: pi×r²×h
Volume of a sphere: [tex]\frac{4}{3}[/tex]×pi×r³
Volume of a hemisphere: [tex]\frac{2}{3}[/tex]×pi×r³
Step-by-step explanation:
You can just apply the formulas to the question:
