Answers
Answer:
I’m not sure what you need but this equation has: indefinitely many solutions because they are equivalent
Step-by-step explanation:
-5.3w+8.0w-11.6=14-25.6+2.7w
2.7w-11.6=14-25.6+2.7w
2.7w-11.6= -11.6+2.7w
what is the slope of the line that passes through the points (7, -5) and (10, -7.5)?
A:
[tex] \frac{5}{6} [/tex]
B:
[tex] \frac{6}{5} [/tex]
C:
[tex] - \frac{5}{6} [/tex]
D:
[tex] - \frac{6}{5} [/tex]
Answers
Answer:
C. [tex]-\frac{5}{6}[/tex]
Step-by-step explanation:
just use the equation [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] So our first point (7,-5) will be [tex]x_1=7,y_1=-5[/tex]and our second point (10, -7.5) will be [tex]x_2=10,y_2=-7.5[/tex] Then substitute[tex]slope=\frac{(-7.5)-(-5)}{(10)-(7)}=\frac{-2.5}{3}=-\frac{5}{6}[/tex]The legs of a right triangle are 6 cm and 12 cm long.

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

A tree is currently 10 feet tall and grows 2 feet per year. Show your work for full credit.
a. Model this scenario with an arithmetic sequence in explicit form. (2)
b. Rewrite the explicit form of the sequence using function notation. (2)
c. How tall will the tree be in 15 years? (1)
Answers
Answer:
(a) An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) 38ft tall
Step-by-step explanation:
The tree is currently 10 feet long and grown 2 feet per year.
The arithmetic sequence is
10 , 12, 14 , 16 , 18 ..............
a( initial value) = 10 , d (common difference) = 2
Explicit forms
(a) An = a +(n-1)d
An = 10 + (n-1)2
= 10 + 2n -2
An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) Height of the tree after 15 years
F(15) = 10 + (15-1)2
= 10 + 28
= 38ft
So the tree will be 38ft tall after 15 years.

Answer:
5. 3050ft³ (rounded to 3 s.f.)
6. 4190ft³(rounded to 3 s.f.)
7. 4600ft³(rounded to 3 s.f.)
Formulas (For easier reference):
Volume of a cone: pi×r²×[tex]\frac{h}{3}[/tex]
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:
5. Volume of cone = pi×9²×[tex]\frac{(16-10)}{3}[/tex]
= 162pi
Volume of cylinder = pi×9²×10
= 810pi
Volume of figure = 162pi+810pi
= 972pi
= 3050ft³ (rounded to 3 s.f.)
6. Volume of sphere = [tex]\frac{4}{3}[/tex]×pi×10³
= 1333[tex]\frac{1}{3}[/tex]pi
= 4190ft³(rounded to 3 s.f.)
7. Volume of hemisphere = [tex]\frac{2}{3}[/tex]×pi×(26÷2)³
= 1464[tex]\frac{2}{3}[/tex]pi
= 4600ft³(rounded to 3 s.f.)

sin^2(a) I believe. Delete my response if needed.
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) :

∠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
