A small radio transmitter broadcasts in a 60 mile radius. If you drive along a straight line from a city 75 miles north of the transmitter to a second city 76 miles east of the transmitter, during how much of the drive will you pick up a signal from the transmitter?

Answer:

4nx5=n-7

-7/19

Step-by-step explanation:

Let's Write this equation step by step.

The sum of 4 times a number and 5

That means: 4nx5

The difference of the number and 7

That means: n-7

Now, combine:

4nx5=n-7

-7/19

ANSWER:

STEP-BY-STEP EXPLANATION:

We have the following expression:

When you raise an exponent to another exponent, multiply therefore:

The quadrilaterals, parallelogram,square, rectangle has rotational symmetry but no reflectional symmetry

A trapezoid has neither a rotational symmetry nor a reflectional symmetry

But for an isosceles with only one pair of parallel sides has a reflectional symmetry but no rotational symmetry

Thus, the correct answer is

an isosceles with only one pair of parallel sides

We have here a special case where the line is vertical. In this case, the line has an "infinite" slope (or it is not defined). Therefore, since the line is vertical and contains the point (10, 14), the line is given by the equation:

The standard form of the line is given by the general equation:

Then, we can rewrite the equation as follows:

We can see that this line contains the point (10,14):

We can see that the vertical line, x + 0y = 10 passes through the point (10, 14).

In summary, the line is given by x + 0y = 10 (A = 1, B = 0, C = 10).

This is a simultaneous system of equations, we would need both equations, to solve for the variables.

we have

2x - 3y = 6 - ---i

x +7y = 2------ii

Let's modify equation ii, x +7y = 2 means x = 2 - 7y

Anywhere we see x in equation i, lets put in 2 - 7y instead

2( 2 - 7y) - 3y = 6

4 - 14y - 3y = 6

4 - 17y = 6

-17y = 2

y = -2/17

Lets put this result in equation ii

Solution

We want to find the equation of the line given in the graph

We can see the four points on the graph where the line pass through

The points are

We first obtain the slope (m)

The formula for finding the slope is given as

Using the points (0,2) and (-4,0) (indeed we can pick any two points, we will still obtain the same answer)

Here

We can use any of the points above to find the equation

Equation of a line is given by

Using (4,4)

Option D is correct

Using (2,3)

Let:

• A ,be the number of millilitres (mL) of solution A used.

• B ,be the number of mL of solution B used.

We know that Dale uses four times as much solution A as solution B, meaning

Now, we know that we will end up with 570 mL of pure alcohol in the final solution. Using the dilution of both A and B (20% means 0.2 and 15% is 0.15) we would have that:

We would have the following system of equations:

Substituting equation 1 in equation 2 and solving for B :

Substituting in equation 1 and solving for A:

This way, we can conclude that 2400 mL of solution A and 600mL of solution B were used.

We will have the following:

*First: We have that the equation of the circle will be given by:

Here (h, k) is the coordinate of the center of the circle and r is the radius of the circle.

*Second: We will replace the center of the circle and determine the radius:

*Third: We determine the radius of the circle by using the point given:

*Fourth: We have the following expression representing the circle:

So, we replace the point (-2, sqrt(5)) to determine whether or not it belongs to the circle, that is:

Thus proving that the point (-2, sqrt(5)) does lie in the circle.

When we're dilating a line, we can either multiply the function value by a constant

or the argument of the function

Since the y-intercept of both functions is the same, then the multiplied quantity was the argument of the function.

We want to know the constant associated to the transformation

We have the following values for both functions

For the same y-value, we have the following correlations

and this is our answer.

Given that H is the circumcenter of the triangle.

It means, the length between each vertex point of the triangle and the point H is the radius of the circle.

Thus, the line DH=CH=BH are the radius of the circle.

It is given that DH=14.

Therefore CH=14.

Hence the value of CH is 14.

The endpoints are a side of a rectangle ABCD in the coordinate plane at A(3,4), B(6,1) Find the equation of the line the given segment

---------------------

Let's rewrite the given equations in the slope-intercept form:

Since:

We can conclude that the lines are parallel.

We are given the following word problem

"61 less than twice Vidy's score​"

Let us translate the word problem into an algebraic expression

Let v represents Vidy's score

twice Vidy's score means 2 times v

61 less than means to subtract 61 from 2 times v

So, the algebraic expression becomes

The equation of the line that goes through the point (5, -1) and is parallel to the given equation is; 3x + 2y = -7.

Recall from line geometry that parallel lines have equal slopes.

Therefore, by computing the slope of the equation given as follows; we have;

3x + 2y = 19.

By rearranging the equation in the slope-intercept form; y = mx + c; we have;

y = (-3/2)x + 19/2

Therefore, the slope of both lines is same and is; -3/2.

Therefore, By using the point slope equation of a straight line; (y - y1) = m (x - x1); we have;

(y - (-1)) = -3/2(x - 5)

2y + 2 = -3x - 5

3x + 2y = -7.

Ultimately, the required equation is; 3x + 2y = -7.

For the division, notice that we can multiply both numbers by 100, to get the following:

then, we can make the long division:

therefore, the result of 59.25 ÷ 0.75 is 79

For the multiplication, we can write the following:

notice that since both factors have 2 digits and 1 digit each after the decimal point, the final result will have 3 digits after the decimal point,

Therefore, the result of 1.06 × 7.3 is 7.738

Answer

The amount of flour left in the bag = 1.82 kg

Explanation

Concetta had 2 kg of flour.

She uses 180 g of the flour to make biscotti.

We are then asked to calculate how much flour is left in kilograms.

Amount of flour left = (Initial Amount of flour) - (Amount of flour used)

Initial amount of flour = 2 kg

Amount of flour used = 180 g = 0.18 kg

Amount of flour left = (Initial Amount of flour) - (Amount of flour used)

Amount of flour left = 2 - 0.18 = 1.82 kg

We will investigate how to determine the end behaviours of polynomial functions.

The function given to us is:

Whenever we try to determine the end-behaviour of any function. We are usually looking for value of f ( x ) for the following two cases:

The most important thing to note when dealing with end-behaviour of polynomial functions is that the behaviour is pre-dominantly governed by the highest order term of a polynomial. The rest of the terms are considered small or negligible when considering end-behaviours of polynomials.

The highest order terms in the given function can be written as:

Then the next step is to consider each case for the value of ( x ) and evaluate the value of f ( x ) respectively.

Similarly repeat the process for the second case:

Combining the result of two cases we get the following solution:
