Answer: ∠T=45°

Step-by-step explanation:

If triangle RST is congruent to triangle LMN, then the angles R=L, S=M, and T=N. Knowing that the sum of angles in a triangle= 180 degrees, then:

∠R+∠S+∠T=180°

∠R=65°

∠M=∠S=70°

180°-∠R-∠S=∠T

180°-65°-70°=

∠T=45°

The number of total bears counted in 2002 will be: A. 1060 bears.

To determine the total bear estimate, we will use the mark-recapture formula. In this formula, we equate the number of the population to MC/R where:

M = Number marked initially

C = Number captured in the second sample

R = The recaptured number

Also, R/C = M/N

For the given problem,

M = 2008

C = 38

R = 72

So, N =  2008 * 38/72

= 1059 approximately 1060 bears.

So, the bear population will amount to 1060.

It can be seen that x = (3 ± √(9 + 32√3)) / 8, which can be expressed in surd form as (3 + √(9 + 32√3)) / 8 or (3 - √(9 + 32√3)) / 8.

To find x using the sine rule, we need to solve the equation:

sine(45) / x = sine(30) / (2x + 2√3)

Simplifying this equation, we have:

(2x - 1) / x = 1 / (2x + 2√3)

Cross-multiplying and simplifying further, we get:

(2x - 1)(2x + 2√3) = x

Expanding the brackets, we have:

[tex]4x^2 + 4\sqrt3x - 2x - 2\sqrt3 = x[/tex]

Rearranging the terms and simplifying, we get:

[tex]4x^2 - 3x - 2\sqrt3 = 0[/tex]

Using the quadratic formula, we can solve for x:

x = (-(-3) ± √((-3)^2 - 4(4)(-2√3))) / (2(4))

x = (3 ± √(9 + 32√3)) / 8

Therefore, x = (3 ± √(9 + 32√3)) / 8, which can be expressed in surd form as (3 + √(9 + 32√3)) / 8 or (3 - √(9 + 32√3)) / 8.

Answer:

La suma de los cuatro ángulos de un cuadrilátero es igual a 360 grados. Entonces, si dos ángulos miden 60° y 80°, la suma de esos ángulos es de 140 grados.

Los otros dos ángulos están en una proporción de 2:9, lo que significa que la suma de sus medidas es de 11 partes. Si representamos las medidas de estos ángulos como 2x y 9x, respectivamente, entonces podemos escribir la ecuación:

2x + 9x = 11 partes

11x = 11 partes

x = 1 parte

Por lo tanto, el ángulo más pequeño mide 2x = 2 partes o 2 × 1 = 2 grados, y el ángulo más grande mide 9x = 9 partes o 9 × 1 = 9 grados.

En resumen, los dos ángulos faltantes miden 2° y 9°.

Step-by-step explanation:

The derivative of the function is f' ( x ) = 9 / ( 4 + 3x ) ( ln 2 )

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = log₂ ( 3x + 4 )³

On simplifying , we get

On taking the derivative of the function , we get

f' ( x ) = d/dx ( log₂ ( 3x + 4 )³ )

d/dx ( log₂ ( 3x + 4 )³ ) = 1/ ln ( 2 ) [ d/dx( 3x + 4 )³ ]

On applying chain rule , we get

f' ( x ) = 1/ ln ( 2 ) 1/( 3x + 4 )³ ( 9 ( 3x + 4 )² )

So , cancelling out the similar terms , we get

f' ( x ) = 9 / ( 4 + 3x ) ( ln 2 )

The vertex is at (1, 4).

The vertex is at (-1, -4).

The axis of symmetry is x = 1.

The axis of symmetry is x = -1.

The x-intercepts are (3, 0) and (-1, 0).

The x-intercepts are approximately (-2.3, 0) and (0.3, 0).

The y-intercept is (0, 3).

The y-intercept is (0, -6).

We have,

To solve the equations using the quadratic formula, we need to rewrite them in the standard form ax² + bx + c = 0.

-x² + 2x + 3 = 0 can be rewritten as -1x² + 2x + 3 = 0

Here, a = -1, b = 2, and c = 3

Using the quadratic formula, we have:

x = (-b ± √(b² - 4ac)) / 2a

x = (-2 ± √(2² - 4(-1)(3))) / 2(-1)

x = (-2 ± √(16)) / -2

x = 1 ± 2

So, x = 3 or x = -1

2x² + 4x - 6 = 0 is already in the standard form with a = 2, b = 4, and c = -6

Using the quadratic formula, we have:

x = (-4 ± √(4² - 4(2)(-6))) / 2(2)

x = (-4 ± √(52)) / 4

x = (-2 ± √(13)) / 2

To find the vertex of each parabola, we can use the formula x = -b / 2a and then substitute the value of x into the equation to find y.

For -x² + 2x + 3 = 0

We have a = -1 and b = 2, so the vertex is at

x = -b / 2a = -2 / (2(-1)) = 1.

Substitute x = 1 into the equation to find y:

y = -1(1)² + 2(1) + 3 = 4.

So the vertex is at (1, 4).

For 2x² + 4x - 6 = 0,

We have a = 2 and b = 4, so the vertex is at x = -b / 2a = -4 / (2(2)) = -1. Substitute x = -1 into the equation to find y: y = 2(-1)² + 4(-1) - 6 = -4.

So the vertex is at (-1, -4).

The axis of symmetry is a vertical line that passes through the vertex.

For -x² + 2x + 3 = 0, the axis of symmetry is x = 1.

For 2x² + 4x - 6 = 0, the axis of symmetry is x = -1.

To find the x-intercepts, we can set y = 0 in each equation and solve for x using the quadratic formula.

For -x² + 2x + 3 = 0, we have:

x = (-2 ± √(2² - 4(-1)(3))) / 2(-1)

x = (-2 ± √(16)) / -2

x = 1 ± 2

So the x-intercepts are (3, 0) and (-1, 0).

For 2x² + 4x - 6 = 0, we have:

x = (-4 ± √(4² - 4(2)(-6))) / 2(2)

x = (-4 ± √(52)) / 4

x = (-2 ± √(13)) / 2

So the x-intercepts are approximately (-2.3, 0) and (0.3, 0).

To find the y-intercept, we need to set x = 0 and solve for y.

Setting x = 0 in -x² + 2x + 3 = 0.

-0 + 0 + 3 = 3

Therefore, the y-intercept is (0, 3).

Setting x=0 in 2x² + 4x - 6.

2(0)² + 4(0) - 6 = -6

Therefore, the y-intercept is (0, -6).

Thus,

The vertex is at (1, 4).

The vertex is at (-1, -4).

The axis of symmetry is x = 1.

The axis of symmetry is x = -1.

The x-intercepts are (3, 0) and (-1, 0).

Answer:

63

Step-by-step explanation:

b x h = A

9 x 7 = 63

Answer: To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the final amount

P is the initial principal (the amount borrowed)

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the time period in years

In this case, we have:

P = $21,000

r = 8.75% = 0.0875

n = 1 (interest is compounded annually)

t = 13 years

So, plugging these values into the formula, we get:

A = 21,000(1 + 0.0875/1)^(1*13)

A = 21,000(1.0875)^13

A = $58,150.51

Therefore, if the loan is paid in full at the end of the 13-year period, $58,150.51 must be paid back, which includes the original principal plus the interest accrued over the 13-year period.

Answer: n = 70

Step-by-step explanation:

The sum of all angles in a triangle is 180 degrees. We know this because the formula for degree measure in a polygon is (180) * (n-2) where n is the number of sides. (ie a square with 4 sides would have 360 total degrees because (180) * (4-2) = 360)

Given the angle of 40 degrees we know that the remaining angles need to add up to 140 degrees. because n = n we can say that 2n = 140 divide by 2 and get n=70

The angles in the circle are as follows:

The central angle of an arc is the central angle subtended by the arc.

The measure of an arc is the measure of its central angle.Therefore,mBC = 107 degrees

The angle subtended by an arc at the center is twice the angle subtended at the circumference.

Therefore, m∠BAC = 107 / 2 = 53.5 degrees

The inscribed angle is half the intercepted arc angle.

Therefore, to find mBC, we solve:

On simplifying , we get

To find the difference between the sample means, we need to multiply the estimated standard error by the t-statistic and then divide by the square root of the sum of the reciprocals of the sample sizes.

Given that the estimated standard error is 2 points, the t-statistic is 1.500, and the sample sizes are n1 = 8 and n2 = 10, we can substitute these values into the formula:

Difference between sample means = (1.500) x (2) / √(1/8 + 1/10)

Calculating the sum of the reciprocals of the sample sizes:

1/8 + 1/10 = 5/40 + 4/40 = 9/40

Difference between sample means = (1.500) x (2) / √(9/40)

A √(9/40) = √(9) / √(40) = 3 / (2 x √(10))

Difference between sample means = 1.500 x 2 x (2 x √(10) / 3)

There are 58 Adventure Scouts slept outside on the camping trip.

Let's denote the number of scouts who slept in a cabin, tent, and outside as c, t, and o, respectively. We know that the total number of scouts is 115, so:

c + t + o = 115

We also know that twice as many scouts slept in a cabin as slept in a tent, so:

c = 2t

And we know that the same number of scouts slept outside as slept in a cabin, so:

o = c

We can use these equations to solve for the number of scouts who slept outside:

c + t + o = 115

2t + t + t = 115 (substituting c = 2t and o = c)

4t = 115

t ≈ 28.75

Since we can't have a fractional number of scouts, we need to round this up or down. However, we also know that the number of scouts who slept outside is the same as the number who slept in a cabin, which means that either c or o must be even (since c is twice t). Therefore, we'll round t up to 29 and use that to solve for c and o:

c = 2t ≈ 58

o = c ≈ 58

Step-by-step explanation:

4 2/3=8/3, times 1/7 (or divide by 7) equals 8/21.

It's important to note that shifting a function involves changing the corresponding variables (x or y) in the equation to achieve the desired translation.

The parabola y = x^2 represents a standard upward-opening parabola with its vertex at the origin (0, 0). To shift this parabola down by 3 units, we subtract 3 from the y-coordinate of each point on the original parabola. Thus, the equation of the shifted parabola becomes y = x^2 - 3.

Similarly, to shift the parabola to the left by 2 units, we subtract 2 from the x-coordinate of each point on the original parabola. The equation of the parabola shifted down by 3 units and to the left by 2 units is y = (x + 2)^2 - 3.

In the shifted parabola, the vertex will be at the point (-2, -3). The parabola retains its general shape, but its position in the coordinate plane has changed. It is now translated 2 units to the left and 3 units down compared to the original parabola y = x^2.
