Answer:
Step-by-step explanation:
y = ½x-6
slope of line = ½
Slope of any perpendicular to the line = -2.
Equation for line of slope -2 that passes through (3,2):
y-2 = -2(x-3)
y = -2x + 8
Answer:
see explanation
Step-by-step explanation:
(a)
Since Y is the midpoint of XZ , then
XY = YZ , that is
4a - 4 = 3a + 2 ( subtract 3a from both sides )
a - 4 = 2 ( add 4 to both sides )
a = 6
(b)
XY = 4a - 4 = 4(6) - 4 = 24 - 4 = 20
XZ = 4a - 4 + 3a + 2 = 7a - 2 = 7(6) - 2 = 42 - 2 = 40
Answer:
The value of pressure at an altitude of 10000 ft = 10
Step-by-step explanation:
Given data
Atmospheric pressure = 14.7
Pressure at 4000 ft = 12.6
If temperature is constant then the atmospheric pressure is varies with the altitude according to law
P (h) = ------ (1)
where k= constant & h = height
12.6 = 14.7
0.857 =
㏑ 0.857 = - 4000 k
-0.154 = - 4000 k
k = 3.85 ×
Thus the atmospheric pressure at an altitude of 10,000 ft is
14.7 × ----- (2)
Product of k & h is
k h = 3.85 × × 10000
k h = 0.385
Put his value of k h = 0.385 in equation (2) we get
14.7 ×
10
This is the value of pressure at an altitude of 10000 ft.
Answer:
C
Step-by-step explanation:
according to sine rule,
sin(30)/8=sin(x)/11
solving above equation will give
x=43.3
Step-by-step explanation:
3 rows of corn provided 270 ears.
therefore 1 for provides 270/3 = 90 ears
so, to get 360 ears of corn, we need 360/90 = 4 rows of corn.
