What is the expression?

Answer:

y=x+3

Step-by-step explanation:

perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.

here is the equation: y=-x+4

the slope is -1

here is the equation to find the slope of the perpendicular line:

-1m=-1

multiply by -1

m=1

here is the new line so far: y=1x+b

now, we can substitute the point (2,5) into the equation, since the equation will pass through that point to find b (the y intercept)

5=1(2)+b

5=2+b

3=b

the equation of the line is y=1x+3, or y=x+3

Hope this helps!

Answer:

$60 in interest

Step-by-step explanation:

To find interest, use the tried and true method of I = Prt (I is the interest, P is the principal, r is the rate, and t is the time (in years))

I = 500* 2 * 6% (What I do is go on and multiply the principal by the time)

I = 1,000 * 6% (Now to convert 6% and 1,000 into fractions)

I = 1,000/1 * 3/50 (Cross-cancel if needed here; The GCF of 50 and 1,000 is 50)

I = 20/1 * 3/1 (Just remove the /1 part here, they're wholes!)

I = 20 * 3 (Multiply and you have your answer!)

I = $60

Answer:

Ivanna after 2 years of 6% intrest will have 561.8 $ in her accout.

Step-by-step explanation:

500 times 6% can be done like 500 x 0.06 which is 30. So 530. Then 530 time the 6% which is 530 x 0.06 is 31.8. So 530 + 31.8 = 561.8$

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.

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

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

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

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° )

[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].
