PLEASE HELP!! S is the center of the circle. Suppose that JK=12, LK=12, NS=8, and PS= 2x - 6. Fine the following

Answer:

Step-by-step explanation:

The figure must also have the rotational symmetry of 180/270°.

In geometry, symmetry is defined as a balanced and proportionate similarity that is found in two halves of an object. It means one-half is the mirror image of the other half. The imaginary line or axis along which you can fold a figure to obtain the symmetrical halves is called the line of symmetry.

Types of symmetries are rotational symmetry, reflection symmetry, translation symmetry, and glide reflection symmetry. These four types of symmetries are examples of different types of symmetry on a flat surface called planar symmetry.

Answer: Choice A) 3n^2

A monomial has exactly one term. So the answer is between choices A and C based on this fact alone. We can rule out choice C as this has a coefficient of 2. Choice A has a coefficient of 3 and an exponent of 2 (so its degree 2). This is a quadratic monomial.

Answer:

total area = K + R = 448  + 1,165.5  = $1,613.5  sq. in.

Step-by-step explanation:

Use formulas for area of Kite and area of rhombus.

K = area of Kite

R = area of rhombus

K = (1/2) *(diagonal 1)*(diagonal 2)

R = (1/2)*(diagonal 1)*(diagonal 2)

K = (1/2)*(28 in.)*(32 in.) = 14 * 32 = 448 sq. in.

R = (1/2)*(37 in.)*(63 in.) = 1,165.5  sq. in.

total area = K + R = 448  + 1,165.5  = $1,613.5  sq. in.

y = - 24

Step-by-step explanation:

[tex]y = (x - 4)(x + 6) \\ plug \: x = 0 \\ y = (0 - 4)(0 + 6) \\ y = ( - 4)(6) \\ y = - 24 \\ \purple{ \bold{ \therefore \: y - intercept = - 24}}[/tex]

Answer:

The other solution is -0.56

Step-by-step explanation:

Quadratic equation :[tex]4x^2 + 45x + 24 = 0[/tex]

General quadratic equation : [tex]ax^2+bx+c=0[/tex]

Om comparing :

a=4

b = 45

c=24

Formula : [tex]x =\frac{-b \pm \sqrt{b^2-4ac}}{2a}[/tex]

Substitute the values in the formula :

[tex]x=\frac{-45 \pm \sqrt{45^2-4(4)(24)}}{2(4)}\\x=\frac{-45 + \sqrt{45^2-4(4)(24)}}{2(4)},\frac{-45 - \sqrt{45^2-4(4)(24)}}{2(4)}\\x=-0.5613,-10.688[/tex]

So, One solution is −10.69.

So, Other solution is −0.56

Hence  the other solution is -0.56

The second solution to this equation is −0.56.

In the given quadratic equation 4x2 + 45x + 24 = 0, the quadratic formula is used to find the solutions, or roots, of the equation.

This formula is x = [-b ± sqrt(b² - 4ac)] / (2a).

For this specific equation, a is 4, b is 45, and c is 24.

Since it's already given that one root is -10.69, the other root should be obtained by substituting the values into the formula and choosing the alternative sign:

x = [-45 - sqrt(45² - 4*4*24)] / (2*4) this calculation would give −0.56, which is the other solution to the equation.

7a²/16

Step-by-step explanation:

Area of the triangle PTS

½ × a × a

a²/2

Length of PS:

sqrt(a² + a²)

asqrt(2)

Length of MS:

¼asqrt(2)

Triangles MCS and TPS are similar

With sides in the ratio:

¼asqrt(2) : a

sqrt(2)/4 : 1

Area of triangle SMC:

A/(a²/2) = [(sqrt(2)/4)]²

2A/a² = 1/8

A = a²/16

Area of PTMC

= a²/2 - a²/16

= 7a²/16

Step-by-step explanation:

This is a much more interesting problem than what we usually see here.

Let's just start by assuming a=1 so we have two unit squares.

PMC and PTC are two congruent triangles, each right triangles with one leg of length 1 and a shared hypotenuse PC.

We'll put it on the grid at P(0,0), T(1,0).

Angle TPM is 45 degrees and PM=1 so

M(cos 45, sin 45) = M(1/√2, 1/√2)

MK has slope -1, thru M, so is

y = -x + √2

C's on that line at x=1, so C's x coordinate is 1, so its y coordinate is √2 - 1

C(1, √2 - 1)

OK, that's enough to compute the area.

P(0,0), T(1,0), C(1, √2 - 1), M(1/√2, 1/√2)

area(PMCT) = area(PTC) + area(PCM)= 2 area(PTC)

The area of a right triangle is half the product of its legs.

area(PMCT) = 2 (1/2) (1) ( √2 - 1)

area(PMCT) =  √2 - 1

When we have sides a, the area scales by a²,

Answer: a²(√2 - 1)

Answer:

y = 11x

Step-by-step explanation:

First we find the slope

m = (y2-y1)/(x2-x1)

   = (11-0)/(1-0)

   = 11/1

=11

We know the y intercept is 0 ( the y value where x is zero)

We can use the slope intercept form of the equation for a line

y = mx+b where m is the slope and b is the y intercept

y = 11x+0

y = 11x

Step-by-step explanation:

The number of periods of REM sleep Georgia has in the 6 hours (390 minutes) as stated in the question is 8.667 periods.

Using the standard time conversion, the number of periods is 8 hours.

To determine the number of periods of REM sleep that Georgia has, we need to divide the total number of minutes of sleep by the interval at which she falls into the REM sleep.

From the given information:

The number of periods of REM sleep she has in 390 minutes of sleep is:

= 390 minutes/ 45 minutes

= 8.667 periods.

NOTE: We have only 360 minutes in 6 hours since 60 minutes = 1 hour.

= 360 minutes/ 45 minutes = 8 periods.

Step-by-step explanation:

Both bags have the numbers 5, 6, 7, 8, 9 and 10. Thus, there are 6 similar number in both bags.

The probability of picking the number 5 in both bags is:

P(5)= 1/10  * 1/10=  1/ 100

It is the same probability of picking the number 6 or 7 or 8 or 9 or 10 in both bags.

P ( 6)= 1/100

P ( 7 ) =  1 /100

P (8)=  1 /100

P ( 9 ) =  1 /100

P ( 10 ) = 1 /100

Answer:

13.04 units to the nearest hundredth.

Step-by-step explanation:

Use the Pythagoras theorem:

c^2 = a^2 + b^2  where a, b and c are the sides of  a right triangle with c the hypotenuse.

In our triangle ( x = length of the hypotenuse):

x^2 = 13^2 + 1^2

x^2 = 169 + 1 = 170

x = √170

= 13.04.

If we are doing this mentally the best we can do is say that the hypotenuse is a small amount greater than 13.

Answer:

q < 7

Step-by-step explanation:

Given:

[tex]\frac{-q}{7} > -1[/tex]

Required:

Find the value of q.

First, multiply both sides by 7

[tex]7 * \frac{-q}{7} > -1 * 7[/tex]

-q > -7

Then, multiply both sides by -1

q < 7

Note that the sign of the inequality changed.

When multiplying or dividing an inequality by a number less than 0 (in other words, a negative numbers), the sign of the inequality will change.

Hence, the solution to the expression above is

q < 7

The bug crawl in total of 90 feet of distance .

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangle triangle, is a triangle in which one angle is a right angle or two sides are perpendicular. The relation between the sides and other angles of the right triangle is the basis for trigonometry.

According to question

Ataut telephone wire extends from the top of a 40-foot tall telephone pole to a stake in the ground 9 feet away

So, according to diagram

AB= 9 feet

AC = 40 feet

BC =[tex]\sqrt{AB^{2} +AC^{2} }[/tex](Pythagoras theorem)

BC = [tex]\sqrt{9^{2} +40^{2} }[/tex]

BC=[tex]\sqrt{81 + 1600 }[/tex]

BC = [tex]\sqrt{ 1681 }[/tex]

BC= 41 feet

As bug start from the stake in the ground up the wire to the top of the

telephone pole. Then the bug crawled down to the bottom of the pole and back to the stake which means perimeter of right angle triangle.

Perimeter of triangle = AB + BC + AC

= 9 + 41 + 40

= 90 feet

Hence, the total distance travelled by bug is 90 feet .

Answer:

x = ± 3, x = ± 2i

Step-by-step explanation:

Given

[tex]x^{4}[/tex] - 5x² - 36 = 0

Use the substitution u = x² then the equation is

u² - 5u - 36 = 0 ← in standard form

(u - 9)(u + 4) = 0 ← in factored form

Equate each factor to zero and solve for u

u - 9 = 0 ⇒ u = 9

u + 4 = 0 ⇒ u = - 4

This indicates there will be 2 real roots and 2 complex roots

Change back to find values of x, that is

u = 9 ⇒ x² = 9 ⇒ x = ± [tex]\sqrt{9}[/tex] = ± 3 ← real roots

u = - 4 ⇒ x² = - 4 ⇒ x = ± [tex]\sqrt{-4}[/tex] = ± 2i ← imaginary roots
