−3(2.5−k)+0.5(7+8k).
Answer:
7k-4
Step-by-step explanation:
(-3)(2.5)+(-3)(-k)+(0.5)(7)+(0.5)(8k)
-7.5+3k+3.5+4k
Then you combine like terms
-7.5k+3k+3.5+4k
(3k+4k)+(-7.5+3.5)
7k+-4
A plane rises from take-off and flies at an angle of 8° with the horizontal runway. When it has gained 850 feet, find the distance to the nearest foot, the plane has flown.
850 ft
The plane has flown approximately ___ feet. (Round to the nearest foot.)
Answer:
[tex]C\approx 5748.2feet[/tex]
Step-by-step explanation:
From the question we are told that
Angle of elevation [tex]\thata=8 \textdegree[/tex]
Height of plane [tex]H=850feet[/tex]
Generally the equation for the Distance flown is given by
[tex]C=\frac{H}{sin \theta}[/tex]
[tex]C=\frac{800}{sin8}[/tex]
[tex]C=5748.237227[/tex]
[tex]C\approx 5748.2feet[/tex]
Therefore Distance flown is
[tex]C\approx 5748.2feet[/tex]
how long will it take a shelf fired from a cliff at an initial velocity of 800 metres per second at an angle of 30 degree below the horizontal to reach the ground 150 metre belowJason control rules of baseball with the horizontal component of velocity of 25 metres per second
0.373 seconds. First, calculate the initial vertical velocity of the shell. 800sin(30) = 800*0.5 = 400 m/s Now the formula for the distance traveled is d = 400 m/s * T + 0.5A T^2 Substituting known values gives. 150 = 400 m/s * T + 0.5*9.80m/s^2 T^2 150 = 400 m/s * T + 4.9 m/s^2 T^2 Arrange as a quadratic formula 0 = 400 m/s * T + 4.9 m/s^2 T^2 - 150 4.9 m/s^2 T^2 + 400 m/s * T - 150 = 0 Now solve for T using the quadratic formula with a=4.9, b=400, and c=-150 The calculated value is 0.373 seconds. Is this value reasonable? Let's check. The initial downward velocity is 400 m/s. So 150/400 = 0.375 seconds. Since the actual time will be a bit less due to acceleration by gravity and since the total time is so short, there won't be much acceleration due to gravity, the value of 0.373 is quite reasonable.

Suppose you flip a fair coin
1000 times. What do you think
is the probability of getting
exactly 500 heads?
Answer:
50
Step-by-step explanation:
first estimate probably 50% depends also in luck
Answer:
about 0.02
Step-by-step explanation:
If you toss a coin 1,000 times the average (mean) number of heads equals 500, yet the probability that you will get exactly 500 heads in 1,000 tosses is about 0.02.
The sum of the measures of two acute angles is always greater than 90 degrees
Answer:
One acute angle will always measure between 0° and 90° . Two acute angles can sum to be either greater than, less than, or equal to a right angle. Two acute angles can be complementary angles (adding to 90° ). Two acute angles alone cannot sum to make a straight angle (180° )
A bacteria culture grows with constant relative growth rate. The bacteria count was 1296 after 2 hours and 531441 after 6 hours. Answer the following questions. 1. What is the relative growth rate
Answer:
1)k=1.50408
2)=64
3)P(t)=64e^(1.50408t)
4)=118098
5)t=6.42 hrs
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW
A bacteria culture grows with constant relative growth rate. The bacteria count was 1296 after 2 hours and 531441 after 6 hours. Answer the following questions.
1. What is the relative growth rate?
2. What was the initial size of the culture?
3. Find an expression for the number of bacteria after t hours.
4. Find the number of cells after 5 hours.
5. When will the population reach 1000000?
To find relative growth rate, expression below can be used
P(t)= Po*e^(kt)
Where k= growth rate
Po= initial amount
t= time in hours
We were given The bacteria count as 1296 after 2 hours and 531441 after 6 hours. This can be expressed below as
P(2)= P(o)e^(2k)= 1296.........eqn(1)
P(6)= P(o)e^(6k)= 531441........eqn(2)
If we find the ratio of the two eqn we have
531441/1296 =[P(o)e^(6k)]/[P(o)e^(2k)]
410.0625= e^(4k)
If we take Ln of both side
ln 410.0625=ln(e^4k)
k=1.50408
1)= k=1.50408
2)
From P(2)= Po*e^(2k)= 1296
1296=Po × e^(2×1.50408)
1296= Po × e^(3.00816)
Po=1296/e^(3.00816)
=64
3) the expression is P(t)=64e^(1.50408t)
4). P(5)=64e^(1.50408×5)
=118098
5) P(t)= 1,000,000
1000000=64e^(1.50408t)
1000000/64 = 64e^(1.50408t)
Ln(15625)=ln[e^(1.50408t)]
9.657=e^(1.50408t)
t=6.42 hrs

f=6/2-g make g the subject
Answer:
[tex]g=\dfrac{2f-6}{f}[/tex]
Step-by-step explanation:
The given equation is :
[tex]f=\dfrac{6}{2-g}[/tex]
We need to find the value of g.
Cross multiplying both sides,
[tex]f(2-g)=6\\\\2f-fg=6\\\\2f-6=fg\\\\g=\dfrac{2f-6}{f}[/tex]
So, the value of g is equal to [tex]\dfrac{2f-6}{f}[/tex].

Solve for x
f f(x) is a linear function, which statement must be true? f(x) has no constant term. f(x) has no x2-term. f(x) has no terms with a coefficient other than 1. f(x) has no x-term. Mark this and return
Answer:
f(x) has not x^2 term.
Step-by-step explanation:
Linear function is in the form of y=mx+b
In the linear function y=mx+b there is a constant term b
There is also an x term.
m is the slope of f(x). The value of 'm' can be any number.
If we have x^2 term in f(x) then it is quadratic function.
Linear function must always have x with exponent 1
True option is f(x) has not x^2 term.
