Answer: see explanation

Step-by-step explanation:

The 10 cm distance is measured perpendicularly to the chord, forming a right angle and bisecting the chord. Thus half of the chord, the segment from the center of the chord, and a radius to the end of the chord form a right triangle. The hypotenuse is 26 cm and one leg is 10 cm, so the other leg is given by the Pythagorean theorem: a^2 + 10^2 = 26^2, giving a = 24 cm. Since a is half the chord, the chord is 2a = 48 cm in length.

Hence, the length of a chord of a circle is [tex]48cm[/tex].

What is the circle?

A circle is defined as a two-dimensional figure, which is round in shape where all the points on the surface of the circle are equidistant from the center point is called “[tex]P[/tex]”.

Here given that,

A circle of radius [tex]26[/tex]cm if the chord is [tex]10[/tex]cm from the center of the circle.

So,

The  [tex]10[/tex]cm from the center of the circle is perpendicular of the chord and the hypotenuse is  [tex]26[/tex]cm .

As we know

[tex]H^2=B^2+P^2[/tex]    .......[tex](1)[/tex]

Substituting the values in the equation [tex](1)[/tex], we get

[tex](26)^2=(10)^2+B^2\\B^2=676-100\\B^2=576\\B=\sqrt{576}\\B=24cm[/tex]

Hence, the length of a chord of a circle is [tex]48cm[/tex].

we get that, the value of x for the given angles in the diagram is 10°.

We can see that:

∠  NMG + ∠ GML = ∠ NML

Substituting the values of the angles in the equation, we get that:

46 ° + 8 x - 5° = 11 x + 11 °

Combining the like terms:

8 x + 41° = 11 x + 11°

Taking variables on one side:

11 x - 8 x = 41° - 11°

Combining the like terms again:

3 x = 30°

Divide both sides by 3:

x = 30° / 3

x = 10°

Therefore, we get that, the value of x for the given angles in the diagram is 10°.

-5 and 7 are real and rational numbers also they are integers.

Numbers which can be written in the form of p/q are rational numbers where q must not be zero.

According to the given question we have to determine what kind of numbers are -5 and 7.

In a most simple way we can say that - 5 is an negative integer and 7 is a positive integer.

But -5 can be written as -5/1 which is a rational number also and 7 can also be written as 7/1 so we can also say they are integers al well as rational numbers.Lastly they are real numbers as they don't have any imaginary part 'i' in it.

The inequality that give the number of logic boards that will give a profit for the product is profit = x($479-$109)-$323,902.

Given that, a company produces a logic board for computers. The annual fixed cost for the board is $323,902, and the variable cost is $109 per board. So, we have to write an inequality which will gives the number of logic boards that will give a profit for the product, if the logic board sells for $479.

We simply use the formula that,

profit + annual fixed cost = number of logic board sold x (logic board sales price-variable cost of logic board)

Let the number of logic board sold be x.

profit + $323,902 = x($479-$109)

profit = x($479-$109)-$323,902

Therefore, we can denote the above listed information in profit = x($479-$109)-$323,902 term. This is the required answer.

Modelling the situation, it is found the price of the ticket without the coupon is of $9 when all the six friends spent $ 42 to buy the tickets.

Total money spent by 6 friends on purchasing of the movie tickets = $ 42

So, the money spent for the purchase of 1 ticket will be calculated by dividing the $ 42 by 6.

So, cost of 1 ticket = 4 42 / 6 = $ 7

Coupon is of $2-off.

This means that with the coupon, $2 is subtracted from the ticket price.

So, price of ticket will be = $ 7 + $ 2 = $ 9.

Alfonso borrowed $750 from the bank with 4% simple interest and borrowed $1,750 from the bank with 3.5% simple interest.

How do we calculate the amount borrowed?

Let:

x = amount borrowed from the bank that charged 4% simple interest

y = amount borrowed from the bank that charged 3.5% simple interest

Therefore, we have:

x + y = 2,500 ............................... (1)

0.04x + 0.035y = 91.25 ............................. (2)

From equation (1), we have:

x = 2,500 - y ....................... (3)

Substituting equation (3) into (2) and solving for y, we have:

0.04(2,500 - y) + 0.035y = 91.25

100 - 0.04y + 0.035y = 91.25

100 - 0.005y = 91.25

-0.005y = 91.25 - 100

-0.005y = -8.75

y = -8.75 / -0.005

y = $1,750

Substituting for y in equation (3), we have;

x = 2,500 - 1,750

x = $750

The rent option will cost 120 more dollars than the outright cost of the computer .

The outright cost of the computer is $864.

The store also offers a rent to own option which will cost $41 per week for 24 weeks.

Therefore, the total cost for the rent option is as follows:

cost of the computer for rent option = 41 × 24

cost of the computer for rent option = 984 dollars

Therefore,

difference in cost = 984  - 864

difference in cost = 120 dollars

The slope of a linear demand curve is negative

The demand curve's negative slope indicates that there is an inverse link between price and demand.

It is true that the demand curve's negative slope indicates an inverse link between price and quantity desired. According to the demand curve, demand declines as prices increase and rises as prices decrease.

This statement is false since it only applies to Giffen products, where the demand curve has a positive slope and a direct correlation between price and quantity desired.

Because unit requests rise when prices decrease and decline when prices rise, the demand curve often slopes downward (i.e., is negative). Demand increases when prices are low, but demand decreases when prices are high.

The easiest way to solve this is to make them all common denominators.

The common denominator for this problem is 24.
