Answer:

rate of interest is 6 percent per annum.

Step-by-step explanation:

Formula for simple interest is given

SI = p*r*t/100

where

SI is simple interest

p is principal

r is the rate of interest

t is the time

_______________________________

Given

p = 6400

SI = 768

t = 2 years

r we have to find

lest sue the above formula and plug the given value in it

768 = 6400*r*2/100

=> 768 = 128r

=> r = 768/128 = 6

Thus, r = 6%

thus, rate of interest is 6 percent per annum.

Answer:

The function f(x) was translated right 3 units and up 2 units.

Step-by-step explanation:

F(x)=(2/3)^x

If we move it right for 3 units, we get

f(x)= (2/3)^(x-3)

If we move up 2 units , we get

g(x)= (2/3)^(x-3) +2

Step-by-step explanation:

3−2(x+1)=2x−7

3+(−2)(x)+(−2)(1)=2x+−7(Distribute)

3+−2x+−2=2x+−7

(−2x)+(3+−2)=2x−7(Combine Like Terms)

−2x+1=2x−7

−2x+1=2x−7

Step 2: Subtract 2x from both sides.

−2x+1−2x=2x−7−2x

−4x+1=−7

Step 3: Subtract 1 from both sides.

−4x+1−1=−7−1

−4x=−8

Step 4: Divide both sides by -4.

−4x−4=−8−4

Answer

1360

Step-by-step explanation:

4x10 is 40 so you'd have to multiply 40x34 which is 1360

136×10 is the amount of water used by the airplane to deliver 34

trips.

Multiplication is a method of finding the product of two or more numbers

Given that Airplanes are sometimes used to fight fires.

A certain airplane can deliver 4 x 10 liters of water in one trip.

We need to find how much water can the  airplane deliver in 34

trips

Let us find the water used for one trip.

1 trip is 4 x 10 liters which is 40 litres.

Now we have to find for 34 trips.

We have to multiply 34 with 40 litres

34×40

Thirty four times forty

1360

Now we have to convert it to the scientific notation 136×10

Hence, 136×10 is the amount of water used by the airplane to deliver 34

trips.

Answer:

14 miles

Step-by-step explanation:

Assuming each horse was only ridden once

then a total of 13 horses were ridden for a total of 182 miles

182 miles / 13 horses  = 14  miles  horse

Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.

Note that the fact that there were 3 riders is irrelevant.

Step-by-step explanation:

Step-by-step explanation:

(1-3i)-(2-i)=

1-2-3i+i=

-1-2i

1-2-3i+i

= -1-2i

Step-by-step explanation:

I simplified it in a simple way by arranging like terms together and did the calculation. Here the like term of 1 is -2 and for -3i it's i. so 1-2= -1 and -3i+i= -2i according to integers rule.

Answer:

4.5 is the range

Step-by-step explanation:

Ok, so it's asking for range, Range means The Highest number minus the smallest number.

What is the highest number? it's "2.3"

What is the lowest number? it's "-2.2"

so subtract those numbers and you get your answer!

Wait... why is the range 4.5? well, you do 2.3-(-2.2) when there are 2 minuses, you switch it to a + sign. so, 2.3+2.2=4.5!

Step-by-step explanation:

Since the graph is nonlinear, you can rule out answers that say or suggest 'constant change.'

Answer:

Independent variable: distance

Dependent variable: number of letters recognized on an eye chart

Step-by-step explanation:

Independent variables are stand-alone. This means that it does not depend on another variable but affects the dependent variable.

Dependent variables are dependent on another variable. When the independent variable changes, dependent variables are changed.

Since the hypothesis is that the distance affects the number of letters recognized,

the distance causes a change in the number of letters recognized not the other way around.

Thus, the dependent variable is the number of letters recognized on the eye chart while the independent variable is the distance.

Answer:x=30

Step-by-step explanation:

So first you have to find x so add all your sides together:

Equation: 45+2x+0.5x+x=150

Combine like terms: 45+3.5x=150

Subtract 45 from -45 -45

both sides: 3.5x=105

Then divide by 3.5: x=30

Now that you have your x substitute it in:

2(30)=60

0.5(30)=15

and the last one is x=30

And there you have all your sides! If you wanna check it just add up all the sides and it should equal 150.

Answer:

264.6

Step-by-step explanation:

Answer:

264.6

Step-by-step explanation:

ok first of all if you are subtracting a negative the it becomes a positive

136 - (-128.6)

136 + 128.6

this is what goes on in my head you don't have to do it this way but i do

100 + 100 = 200

30 + 20 = 50

6 + 8.6 = 14.6

200 + 50 + 14.6 = 264.6

x= 1 + 5 √2

x= 1 - 5 √2

The values of x in the expression are x = 1 + √51 and x = 1 – √51.

We have,

Expanding the left side of the equation, we get:

(x – 1)2 = x2 – 2x + 1

So, we have:

x2 – 2x + 1 = 50

Subtracting 50 from both sides, we get:

x2 – 2x – 49 = 0

Now, we can use the quadratic formula to solve for x:

x = [2 ± √(22 – 4(1)(–49))] / (2)

x = [2 ± √(204)] / (2)

x = [2 ± 2√51] / (2)

x = 1 ± √51

Therefore,

The values of x are x = 1 + √51 and x = 1 – √51.

Answer:

29/24π

Step-by-step explanation:

To get coterminal angles, you simply have to add or subtract 2π

In this problem, we are looking for a coterminal angle that is between

0 and 2π, so we will add 2π to −19/24π.

−19/24π+2π

=

−19/24π+48/24π

=

29/24π

29/24π

is the answer to the question.

[tex]\frac{11\pi }{4}[/tex] is the coterminal between of [tex]\frac{19\pi }{4}[/tex] between (0, 2[tex]\pi[/tex]).

Coterminal angles are the angles that have the same initial side and share the terminal sides.

To find the coterminal angle of an angle, we just add or subtract multiples of 360 degrees from the given angles.

According to the given question.

We have

Angle = [tex]\frac{19\pi }{4}[/tex]

Since, the coterminal angle is to be between 0 and 2π.

Therefore, we subtract 2π from [tex]\frac{19\pi }{4}[/tex]to get coterminal angle.

⇒ [tex]\frac{19\pi }{4} -2\pi[/tex] [tex]= \frac{19\pi -8\pi }{4} =\frac{11\pi }{4}[/tex]

Hence, [tex]\frac{11\pi }{4}[/tex] is the coterminal between of [tex]\frac{19\pi }{4}[/tex] between (0, 2[tex]\pi[/tex]).
