ANSWER

23.6 feet

EXPLANATION

The given triangle is a right triangle.

The hypotenuse is 27 ft.

The given angle I s 29°

The unknown side x, is adjacent to the given angle.

We use the cosine ratio to get,

[tex] \cos(29 \degree) = \frac{adjacent}{hypotenuse} [/tex]

[tex] \cos(29 \degree) = \frac{x}{27} [/tex]

We multiply both sides by 27 to get;

[tex]x = 27\cos(29 \degree) [/tex]

[tex]x = 23.6ft[/tex]

to the nearest tenth.

Answer:

x = 23.6

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

To find the value of x

From the figure we can see a right angled triangle, ABC

Cos 29 = Adjacent side/Hypotenuse

 = AB/AC

 = x/27

x = 27 * Cos 29

 = 27 * 0.87

 = 23.6

Therefore x = 23.6

Answer:

$8.10

Step-by-step explanation:

First step is to determine the tax rate, which you can easily figure out with the first sentence, since you have $4.48 tax on $56 purchase.  The tax rate is then:

TR = 4.48 / 56 = 0.08 or 8%

Now, the question can be rephrased as "What's the total difference, including taxes, between a purchase of $66.25 (A) and another of $58.75 (B)"

Let's find out the total cost for both purchases:

A = 66.25 * 1.08 = 71.55 (66.25 + 8% tax)

B = 58.75 * 1.08 = 63.45 (58.75 + 8% tax)

Difference is then 71.55 - 63.45 = 8.10

The $66.25 purchase of goods will cost $8.10 more than the $58.75 purchase of goods once the 8% tax is applied.

Step-by-step explanation:

in this exercise, when asking you to simplify the fraction, you are actually asking to rationalize the denominator, that is, you operate the fraction until any square root of the denominator disappears

In order to do that, the first thing to do is multiply both the denominator and the numerator by the root that you want to eliminate, that is, by [tex]\sqrt{5}[/tex] :

[tex]\frac{5}{\sqrt{5}}*\frac{\sqrt{5} }{\sqrt{5} }  =\frac{5*\sqrt{5} }{\sqrt{5} *\sqrt{5} } = \frac{5\sqrt{5} }{\sqrt{5} ^{2} } =\frac{5\sqrt{5} }{5} =\sqrt{5}[/tex]

Answer:

x= -1, y= 1

Step-by-step explanation:

2x + 6y = 4.........(1)

8x - 5y = 45........(2)

multiply equation (1) by 4

8x + 24y = 16......(3)

subtract equation (3) by (2)

29y = 29

y = 1

then substitute y=1 in equation (1)

2x + 6(1) = 4

solving for x

x = -2/2 = -1

The solution to the system of equations 2x + 6y = 4 and 8x - 5y = 45 is x = 5 and y = -1, found by using the method of elimination.

To find the solution of the system of equations containing 2x + 6y = 4 and 8x - 5y = 45, we will use the method of elimination.

First, we will manipulate the first equation to line up with the second equation regarding the x coefficient. We do this by multiplying the entire first equation by 4, giving us 8x + 24y = 16 which we will call equation (3).

Next, we subtract equation (2) from equation (3) to eliminate the x variable: (8x + 24y) - (8x - 5y) = 16 - 45, leading to 29y = -29.

Dividing both sides by 29 gives us the value of y: y = -1.

To find x, substitute y = -1 back into the original equation (1): 2x + 6(-1) = 4. Solving for x we get 2x - 6 = 4, therefore 2x = 10 and x = 5.

We can conclude that the solution to the system of equations is x = 5 and y = -1.

Answer:

The current at t = 0 is

[tex]I (0) = 2[/tex] units of current

Step-by-step explanation:

If the current flowing through an electric circuit is defined as the derivative of the charge as a function of time and we have the equation of the charge as a function of time, then, to find the equation of the current, we derive the equation of the charge.

[tex]q (t) = 3t ^ 2 + 2t-5[/tex]

[tex]\frac{dq(t)}{dt} = 3 (2) t ^ {2-1} +2t ^ {1-1} -0[/tex]

Simplifying the expression we have:

[tex]\frac{dq(t)}{dt} = 6t + 2t ^0\\\\\frac{dq(t)}{dt} = 6t + 2 = I (t)[/tex]

Finally, the equation that defines the current of this circuit as a function of time is:

[tex]I (t) = 6t +2[/tex]

Now to find the current at t = 0 we make [tex]I (t = 0)[/tex]

[tex]I (0) = 6 * 0 +2[/tex]

[tex]I (0) = 2[/tex] units of current

ANSWER

6w = 100

EXPLANATION

The formula for calculating the perimeter of a rectangular building is P=2l +2w.

From the question, the perimeter of the garden is 100 feet.

It was given that, the length of a rectangular garden is 3 times the width.

This implies that,

[tex]l = 3w[/tex]

We substitute into the formula to get:

[tex]2(3w)+2w = 100[/tex]

[tex]6w+2w = 100[/tex]

This simplifies to:

[tex]8w = 100[/tex]

The equation that can be used to find the width of the rectangular garden is 8w = 100.

To find the width of the rectangular garden, we can set up an equation based on the given information. Let's say the width of the garden is w. If the length is 3 times the width, then the length would be 3w. The perimeter of a rectangle is calculated by adding up all the sides, so in this case, it would be 2w + 2(3w) = 100 feet. Simplifying this equation gives us 8w = 100 feet. Therefore, the equation that can be used to find the width of the garden is 8w = 100.

Answer:

x = 4.1

Step-by-step explanation:

The line segment from the centre to the chord is a perpendicular bisector Thus one half of the chord = 15.6 ÷ 2 = 7.8

Consider the right triangle formed with legs x and 7.8 and hypotenuse 8.8

Using Pythagoras' identity on the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other two sides, then

x² + 7.8² = 8.8²

x² + 60.84 = 77.44 ( subtract 60.84 from both sides )

x² = 16.6 ( take the square root of both sides )

x = [tex]\sqrt{16.6}[/tex] ≈ 4.1

Equation of tangent line : y= -2x +6

Step-by-step explanation:

the instantaneous rate of change of the function [tex]f(x) = 6x^2 - x[/tex] at the point (-1,7)

To find instantaneous rate of change we take derivative

[tex]f(x) = 6x^2 - x[/tex]

[tex]f'(x) = 12x-1[/tex]

Now we plug in  -1 for x

[tex]f'(-1) = 12(-1)-1=-13[/tex]

Instantaneous rate of change = -13

the equation of the line tangent to the function f(x) at the point (1,4)

[tex]f(x) = -x^2 + 5[/tex]

To find slope of tangent line take derivative

[tex]f'(x) = -2x[/tex]

Plug in 1 for x . given point is (1,4)

[tex]f'(1) = -2(1)=-2[/tex]

so  slope = -2

use equation [tex]y-y1=m(x-x1)[/tex]

[tex]y-4=-2(x-1)[/tex]

[tex]y-4=-2x+2[/tex]

Usually you prove the medians are concurrent way before you get the Ceva's Theorem.  But we do the problem as given.  Next time try to include the whole problem in the photo.

FA=FB, BE=EC, CG=GA

Answer: C. Definition of median

The medians go to the midpoints of the sides, so we have congruent segments from the foot.

FA/FB=1, BE/EC=1, CG/GA=1

Answer: A. Division of equal segment lengths yields 1

This one is cut off so we can't read the full justification, but we have equal segments so their ratio is 1.

(FA/FB)(BE/EC)(CG/GA)=1

Answer: E. Substitution property

Again the justification is cut off, but we have three things equal to 1, when we multiply them together we still get 1.

Medians are Concurrent

Answer: B. Ceva's Theorem

This is really the converse of Ceva's Theorem; we have the required ratio product equal to 1, so we know the medians are concurrent.   Technically they might be parallel (which is concurrent in the projective sense, meeting at infinity).  So we really need to show they're not parallel as well, which they can't be, but they left that part out.

14√2

Step-by-step explanation:

The answer to this question is:

y = -2x - 1

Answer:

False

Step-by-step explanation:

The angle between a tangent and radius is right.

Use the converse theorem of Pythagoras to determine.

If the square on the longest side is equal to the sum of the squares on the other two sides then the triangle is right and the segment is a tangent.

longest side = 13.1 ⇒ 13.1² = 171.61

11.3² + 6.65² = 127.69 + 44.2225 = 171.9125

Since 171.61 ≠ 171.9125 the line is not a tangent

The area of a circle is

[tex]a = r {}^{2} \pi[/tex]

So we get

[tex]a = 2.5 {}^{2} \pi[/tex]

so we get 19.6 rounded to the nearest tenth

Now we subtract that from the area of the square which is 25

We get 5.4

So the answer shoild be 5.4ft

Hopefully this is correct and helps you!

Answer:

5.4 ft²

Step-by-step explanation:

The area of the yellow region = area of square - area of circle

area of square = 5² = 25

note that the diameter of the circle = 5, thus radius = 2.5

area of circle = π × 2.5² = 6.25π

yellow region = 25 - 6.25π ≈ 5.4 ft²
