Using a linear function, it is found that he would have to ride his bicycle 7.9 miles a day to meet his goal.

A linear function is modeled by:

y = mx + b

In which:

For this problem, we have that:

When x = 4, y = 39.6, hence:

39.6 = 4m + 8

4m = 31.6

m = 31.6/4

m = 7.9.

Answer:

The Martins used their sprinkler for 35 hours, while the Kellys used their sprinkler for 25 hours.

Step-by-step explanation:

As the Martins and the Kellys used their sprinklers for 60 hours combined last summer, and the water output rate of the Martins' sprinkler is 30 liters per hour, while the Kelly's is 35 liters per hour To determine how many hours each family used their sprinklers, knowing that in total 1925 liters of water were used, the following logical reasoning must be carried out:

There is a 5 liter difference between the Kelly sprinkler and the Martin sprinkler. If both used 30 liters of water per hour, for 60 hours 1800 liters (30 x 60) would have been used. Therefore, there is an excess of 125 liters that corresponds to an excess of consumption, attributable to the Kelly sprinkler, which consumes 5 liters more of water per hour than the Martin's. Thus, since 125/5 equals 25, in total the Kellys used their sprinkler for 25 hours, while the Martins did it for 35 hours.

This reasoning is proved with the following calculation:

25 x 35 = 875

35 x 30 = 1,050

875 + 1,050 = 1,925

For these types of problems, You must look at the coefficients and variables separately and find the GCF for each. Then, combine the two

First, take 12 and 9

Factors of both

9- 1, 3, 9

12- 1, 2, 3, 4, 6, 12

So the gcf of 12 and 9 is 3

Now do the variables a and a^2

a^2 is just a twice

The GCF is a

Now combine a and 3

Step-by-step explanation:

12% of 50=6 pennies

40% of 50= 20 dimes

6+5= 11 nickels

11+20+6= 37 coins

50 total coins-37= 13 quarters

13 quarters = $3.25

20 dimes = $2.00

11 nickels = $0.55

[tex]\frac{1}{\sin \left(10^{\circ \:\:}\right)}\:\:\frac{1}{\sin \:\left(10^{\circ \:\:}\right)}=4[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{1}{\sin \left(10^{\circ \:}\right)}-\frac{\sqrt{3}}{\cos \left(10^{\circ \:}\right)}=4[/tex]

Taking the left-hand side and solving it

[tex]\frac{1}{\sin \left(10^{\circ \:}\right)}-\frac{\sqrt{3}}{\cos \left(10^{\circ \:}\right)}[/tex]

as

[tex]\frac{1}{\sin \:\left(10^{\circ \:\:}\right)}=5.76[/tex]

and

[tex]\frac{\sqrt{3}}{\cos \left(10^{\circ \:\:}\right)}=1.76[/tex]

so the expression becomes

[tex]\frac{1}{\sin \left(10^{\circ \:\:}\right)}\:\:\frac{1}{\sin \:\left(10^{\circ \:\:}\right)}=5.76-1.76[/tex]

                           [tex]=4[/tex]

Thus, we conclude that

[tex]\frac{1}{\sin \left(10^{\circ \:\:}\right)}\:\:\frac{1}{\sin \:\left(10^{\circ \:\:}\right)}=4[/tex]

Answer and Explanation:

No, they did not use a ruler to compute the values of trig functions. They used geometry to prove theorems about trigonometry, then used those results and ordinary computations involving addition, subtraction, multiplication, division, and square roots to determine the entries in trigonometric tables.

Claudius Ptolemy (85 C.E.–165) created the first trig tables that we know of, and he included proofs of the theorems he used. One of the main theorems he used is what is now called Ptolemy’s theorem.

In order to prove his sum and difference forumlas, Ptolemy first proved what we now call Ptolemy’s theorem.

Ptolemy’s theorem. The product of the diagonals of a cyclic quadrilateral is equal to the sum of the products of the opposite sides.

A cyclic quadrilateral is a quadrilateral inscribed in a circle as ABCD. Ptolemy’s theorem says:

AC ⋅ BD = AB ⋅ CD + AD ⋅ BC

When one of the diagonals (like ) is a diameter of the circle, that gives you a way to determine the trig functions for sum and differences of angles.

Sometimes, the sum and difference formulas for sine and cosine are still called Ptolemy’s formulas.

sin(α + β) = sin α cos β + cos α sin β

cos(α + β) = cos α cos β − sin α sin β

sin(α − β) = sin α cos β − cos α sin β

cos(α − β) = cos α cos β + sin α sin β

Ptolemy started with angles he knew the trig functions for. These included angles in various isosceles triangles: 45°-45°-90°, 60°-60°-60°, and 36°-72°-72°, the last one described by Euclid in Proposition IV.10. That gave him the trig functions for 36°, 60°, and 90°. Using half-angle formulas (mentioned by Hipparchus (190–120 B.C.E.), he could compute trig functions for half of those angles and a quarter of those angles. Then using the sum and difference formulas he computed the rest of the numbers in his trig table.

The absolute value of the equation will not work because the value of x would have to be negative for the perimeter to be 6 ft plus or minus 1.5 ft.

The perimeter of the rectangle is given as:

Perimeter = 2(Length + Breadth)

The perimeter of a rectangle is 6 feet plus or minus 1.5 feet.

So, we have:

Perimeter = 2(Length + Breadth) =  6 feet ± 1.5 feet.

Then  Substitute values for length and width

2(Length + Breadth) =  6 feet ± 1.5 feet.

2(4 + x) =  6 feet ± 1.5 feet.

Now,

2(4 + x) =  6 feet + 1.5 feet.

8 + 2x = 6.5 ft

2x = 6.5 - 8

x = -0.25 ft

2(4 + x) =  6 feet - 1.5 feet.

8 + 2x = 4.5 ft

2x = 4.5 - 8

x = -1.75ft

Here Both values of x are negative.

This means that the absolute value model can't work, because a rectangle cannot have a negative dimension.

According to the given statement the volume of medicine will give to the patient = 0.27ml.

A substance's density is defined as its mass per unit volume. The most common symbol for density is, but the Latin letter D is also an option.

Density is an important topic because it tells us which compounds will float and which will sink when placed in some kind of liquid. Substances float in general if their density is smaller than the density of the liquid in which they are immersed.

ρ = m/v

ρ = density

m = mass

V = volume

Medicine = 4500mg

The medication comes in 5g/0.3mL

We know that:

mL = mg / 1000

So,

ml = 4500/1000

    = 4.5ml

Formula for finding volume = weight/density

                                              = 4.5/(5/.3)

                                              = (4.5 * 0.3)/5

                                               = 0.27ml

According to the given statement the volume will give to the patient = 0.27ml.
