Answer:

Exact form: 65/24

Decimal form: 2.7083

Mixed number form: 2 17/24

Step-by-step explanation:

4 3/8 - 1 2/3 = 2 17/24

The answer explains the positive and negative square roots of 64.

When dealing with the square roots of a number like 64, remember that the square root of 64 is 8, both positive and negative. This is because (-8) x (-8) equals 64 just like (8) x (8) equals 64, following the rule that multiplying two negative numbers results in a positive number.

3(y-4) =2y+6

3y - 12 = 2y +6

y = 18

so length is 42 in.

width is 14 in.

After solving the given equations, the length of the rectangle is 42 inches and the width of the rectangle is 14 inches.

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

The given data in the question,

According to the given diagram,

Length of the rectangle, L = 2y + 6 inches    (i)

Width of the rectangle, W = y - 4 inches   (ii)

The width of the rectangle is 1/3 of the length,

1/3(2y + 6) = (y - 4)

2y + 6 = 3y - 12

y = 18.

Substitute y = 18 in equation (i)

L = 2(18) + 6

L = 42 inches

Substitute y = 18 in equation (ii)

W = (18 - 4)

W = 14 inches.

Answer:

It will travel 9 miles in 10 minutes

Step-by-step explanation:

A car travels 9/10 miles/minute

In 10 minutes, it will travel

10*9/10 = 9 miles

Final answer:

A car traveling at 9/10 of a mile per minute will travel 9 miles in 10 minutes by simply multiplying the car's speed by the time traveled.

Explanation:

To calculate how far a car traveling at a speed of 9/10 of a mile per minute will travel in 10 minutes, we simply multiply the speed of the car by the amount of time it travels.

Speed of car = 9/10 mile/minute

Time = 10 minutes

Distance traveled = Speed of car × Time

Distance traveled = (9/10) mile/minute × 10 minutes

Now we perform the multiplication:

Distance traveled = 9/10 × 10

Distance traveled = 9 miles

Answer:

- q² - q + 72

Step-by-step explanation:

To express the given expression as a polynomial in standard form, we would first multiply the individual elements in one parenthesis with the elements in the second.

We would then rearrange the outcome and simplify it algebraically.

The arrange it in the order of the unknown variable.

As such,

(9+q)(8-q) = 9(8-q) +q(8-q)

= 72 -9q + 8q - q²

= 72 - q - q²

= - q² - q + 72

To form the expression (9+q)(8-q) into a polynomial in standard form, we multiply the terms using the distributive property to get -q² - q + 72.

The student has asked for the expansion of a binomial expression into polynomial form, in this case, expanding (9+q)(8-q). The process involves using the distributive property, also known as the FOIL method (First, Outer, Inner, Last), to multiply each term in the first binomial by each term in the second.

Expanding the binomials, we have:

First: 9 × 8 = 72

Outer: 9 × (-q) = -9q

Inner: q × 8 = 8q

Last: q × (-q) = -q²

Combining like terms (-9q and 8q) gives -q and then adding to the remaining terms, we have:

72 - q - q²

Reordering to get the polynomial in standard form (highest degree first), the result is:

-q² - q + 72

(w/3)-10

Hope this helps!

w/3 - 10 is an expression for the above-described series of operations.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Given, divide w by 3, then subtract 10 from the result Do not simplify any part of the expression.

We need to Create an expression for the above sequence

divide w by 3

=> w/3

then subtract 10

=> w/3 - 10

Since it's written in the problem that does not simplify hence, we would simplify this equation further.

Therefore, an expression for the sequence of operations described above is w/3 - 10

Answer:

A) The graph represents the data appropriately.

Step-by-step explanation:

The graph above is a true representation of data showing the percent of political parties people who agreed with court.

From the graph above, three categories of political parties people are concerned; which are, the Democrats, the Republicans and the Independents.

It can therefore be deduced that 62% of the Democrats agreed with court. By implication, the percent of the Democrats who disagreed with court is 38%. Conversely, 54% of people agreed with court for both the Republicans and the Independents respectively. This implies that the percent of both the Republicans and the Independents who did not agree with court is 46% respectively.

However, the graph fails to provide us with information about what the people agree on; probably the outcome of an election or appointment of a minister.

The graph is not misleading in any way and it is not necessary that the vertical scale begin at zero. Therefore, the data represents the graph appropriately.

Answer:

x =-1

y =-1

Step-by-step explanation:

to solve this system of equation, using substiution method

3x-4y=1 ........................ equation 1

x=2y+1 ............................  equation 2

subbstitute for x into equation 1

3x-4y=1 ........................ equation 1

3(2y + 1) - 4y = 1

6y + 3 -4y = 1

2y + 3 = 1

collect the like terms

2y = 1- 3

2y= -2

divide both sides by  the coefficient of y which is y

2y/2 = -2/2

y = -1

put the value of y =-1 into equation 2

x=2y+1 ............................  equation 2

x = 2(-1) + 1

x = -2 + 1

x = -1

therefore x =-1 y = -1

Transformations can be applied to functions to change the appearance of

the (slope and intercept) of the function.

The result of the transformation are presented as follows;

Reasons:

The given function is; f(x) = 3·x + 2

The function -5·(3·x + 2) is the same as -5 × f(x) = -f(x)

Therefore;

-5·(3·x + 2)  → -5·f(x)

The function 3·x - 5 + 2 = 3·x + 2 - 5 = f(x) - 5

Therefore;

3·x - 5 + 2  → f(x) - 5

The function 3·(x - 5) + 2 by comparison to 3·x + 2 is obtained when x is replaced by (x - 5), therefore;

f(x) = 3·x + 2

f(x - 5) = 3·(x - 5) + 2

3·(x - 5) + 2 → f(x - 5)

The function 3·(-5·x) + 2 is obtained when x in f(x) is replaced by (-5·x),

which gives;

f(x) = 3·x + 2

∴ f(-5·x) = 3·(-5·x) + 2

Which gives;

3·(-5·x) + 2 → f(-5·x)

Answer:

t = 1.277 sec and t = 2.848 sec

Step-by-step explanation:

This problem is much more easily done by graphing it than by computing it using algebra.

The values of t we're looking for are the ones that make x = 0, so we want the solutions of [tex]0.6sin(2t)+0.4cos(2t)=0[/tex] on the interval [0, 3].

According to the graph, this is true when t = 1.277 seconds and t = 2.848 seconds.

Answer:

t = 1.28, 2.85

Step-by-step explanation:

x = 0.6sin(2t)+0.4cos(2t)

x = 0, so

0.6sin(2t)+0.4cos(2t) = 0

0.6sin(2t) = -0.4cos(2t)

Convert into tan(2t) by dividing both sides by 0.6cos(2t):

tan(2t) = -0.4/0.6

tan(2t) =-2/3

Since t lies in [0,3] ,

2t lies in [0,6]

tan(2t) =-2/3

Basic angle:

0.5880026035

Tan is negative is second and fourth quadrants

Answer:

the equation is y = (-2/15 in/min)x + 43 in

Step-by-step explanation:

We'll represent elapsed time with the letter t.  Then 12 p.m. corresponds to t = 0 sec.  Between 12 p.m. and 12:15 p.m., the change in time was 15 min and the change in water depth was (45 - 41) in., or 4 in.

Thus, the water depth changes by 4 in (a decrease) over 30 min.  

Part A:  The water depth rate of change is -4 in/30 min, or -2 in/15 min, or

(-2/15 in)/min (the depth is decreasing).

Part B:  We need to derive a linear function that describes the water depth at any given time x (or t).  Two points on the graph of this line are

(15 min, 45 in) and (35 min, 41 in):  the 'run' is 30 min and the 'rise' is -4 in.

As in Part A, the slope of this line is (-2/15 in)/min.

The desired equation is then y = mx + b, or 45 in = (-2 in/15 min)(15 min) + b, or 45 in = 2 in + b, or  43 in = b.  Then, in its most general form,

the equation is y = (-2/15 in/min)x + 43 in
