Any number besides 20, 30, 40, 50, 21, 31, and 41 should work. The numbers with 0s have no ones and the numbers with 1s have only one one.
Answer:
given x+1 > 10,
x > 10 - 1
x > 9
which means x MUST BE more than 9 , which also means 9 isnt included in the inequality therefore x = 9 is not a solution.
Answer:
Step-by-step explanation:
In Δ ABC & ΔADC
AC bisect ∠BCD given
∠ACB ≅ ∠ACB AC bisect ∠BCD
DC ⊥ AD Given
BC ⊥ AB Given
∠ABC = ∠ADC Right angles are ≅
AC ≅ AC Common to both triangle ΔABC & ΔADC
ΔABC ≅ ΔADC AAS congruent
BC ≅ DC CPCT
Correct question is;
A football is kicked up into the air. Its height, H, above the ground, in meters, at t seconds can be modelled by () = 24 − 4.9²
(a) Determine the expression for the instantaneous rate of change in height at time t.
(b) Determine ' (2) What does ' (2) represent?
Answer:
A) '() = 24 − 9.8
B) '(2) = 4.4 m/s
It means that at a distance of 2 m above the ground, the speed of the ball is 4.4 m/s
Step-by-step explanation:
We are given the function to represent the height as;
() = 24 − 4.9²
A) expression for the instantaneous rate of change in height at time t will be gotten by differentiation of the height function. Thus;
'() = 24 − 9.8
B) '(2) = 24 - 9.8(2)
'(2) = 4.4 m/s
This means that at a distance of 2 m above the ground, the speed of the ball is 4.4 m/s
(0,0)(1,2)......(0,0) is the origin
slope = (2-0) / (1-0) = 2/1 or just 2
y = mx + b
slope(m) = 2
(1,2)...x = 1 and y = 2
now we sub, we r looking for b, the y intercept
2 = 2(1) + b
2 = 2 + b
2 - 2 = b
0 = b
ur equation is : y = 2x + 0...or just y = 2x
