How many 3 inch segments are in a line 120 inches long

Answer:

base = [tex]x^4 - 3x^3+11x-4[/tex]

Step-by-step explanation:

An isosceles triangle has 2 sides of equal length (a) and base (b)

⇒ perimeter of an isosceles = 2a + b

Given:

[tex]\implies \textsf{perimeter}=2a+b[/tex]

[tex]\implies 7x^4 - 3x^3-x-6=2(3x^4 - 6x-1)+b[/tex]

[tex]\implies 7x^4 - 3x^3-x-6=6x^4 - 12x-2+b[/tex]

[tex]\implies x^4 - 3x^3+11x-4=b[/tex]

Therefore, base = [tex]x^4 - 3x^3+11x-4[/tex]

Answer:

Perimeter=sum of sides

[tex]\\ \tt\longmapsto 3x^4-6x-1+3x^4-6x-1+y=7x^4-3x^3-x-6[/tex]

[tex]\\ \tt\longmapsto 6x^4-12x-2+y=7x^4-3x^3-x-6[/tex]

[tex]\\ \tt\longmapsto y=x^4-3x^3+11x-4[/tex]

As per questions,

Angle SKR = 90° (Diagnols dissecting each other in a Kite forms a right angle)

[Option C]

Angle RAT = 32° (Given RAT means that the value is given for the middle alphabet, which means A is 64°. As RAK is half of full angle A, so, 64÷2 )

[Option A]

Angle ARS = 116° (180°-64° = 116°)

[Option D]

Angle KRS = 58° (We know that ARS is 116°, So, KRS is its half, which means 116÷2)

[Option B]

All of the above as all the given sides have 90° angle.

[Option D]

Answer:

y = 6.20 + 12.4(x - pi/4)

Step-by-step explanation:

dy/dx = 2e^x secx + 2e^x secx * tanx= 2e^x secx (1 + tanx)

At x = pi/4, use sec(pi/4) = [tex]\sqrt{2}[/tex]. tan(pi/4) =1

so dy/dx = 2e^(pi/4) * [tex]\sqrt{2}[/tex] * (1 + 1) = [tex]4 \sqrt{2} e^{\pi/4}[/tex] ≈ 12.4 (This is the slope of the tangent line)

When x = pi/4, y =  2e^(pi/4) * [tex]\sqrt{2}[/tex]  = [tex]2 \sqrt{2} e^{\pi/4}[/tex]= 6.20

Then the equation of the tangent line is

y = 6.20 + 12.4(x - pi/4)

Using the z-distribution, as we have the standard deviation for the population, we have that the correct option is:

The p-value is of 0.0772. Fail to reject the null hypothesis that there is no difference in the GPA's.

At the null hypothesis, we test if there is no difference in the means, that is:

[tex]H_0: \mu_T - \mu_H = 0[/tex]

At the alternative hypothesis, we test if there is a difference, that is:

[tex]H_1: \mu_T - \mu_H \neq 0[/tex]

For each sample, we have that:

[tex]\mu_T = 3.22, s_T = \frac{0.002}{\sqrt{50}} = 0.00028284271[/tex]

[tex]\mu_H = 3.24, s_H = \frac{0.08}{\sqrt{50}} = 0.01131370849[/tex]

Hence:

[tex]\overline{x} = \mu_T - \mu_H = 3.22 - 3.24 = -0.02[/tex]

[tex]s = \sqrt{s_T^2 + s_H^2} = \sqrt{0.00028284271^2 + 0.01131370849^2} = 0.0113[/tex]

It is given by:

[tex]z = \frac{\overline{x} - \mu}{s}[/tex]

In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis, hence:

[tex]z = \frac{\overline{x} - \mu}{s}[/tex]

[tex]z = \frac{0.02 - 0}{0.0113}[/tex]

[tex]z = -1.77[/tex]

Using a z-distribution calculator, considering a two-tailed test, as we are testing if the mean is different of a value, with z = -1.77, it is found that the p-value is of 0.0772.

Since the p-value is greater than the significance level of 0.05, the correct option is:

The p-value is of 0.0772. Fail to reject the null hypothesis that there is no difference in the GPA's.

The value of sin2 Θ is in the 4th quadrant is -24/25

Explanation:

Given the expression of cosΘ= 3/5 with Θ in quadrant 4;

According to SOH, CAH TOA;

cosΘ= adjacent/hypotenuse

Get the opposite

5² = opp² + 3²

opp²  = 25 - 9

opp² = 16

opp = 4

SinΘ = opp/hyp

SinΘ = 4/5

Sin2Θ = 2sinΘ cosΘ

Sin2Θ = 2(-4/5)(3/5)

Sin2Θ = -24/25

Hence the value of sin2Θ is in the 4th quadrant is -24/25

Answer:

y = -1x+2

Step-by-step explanation:

(1,1)(7,-5)

y2-y1/x2-x1 = slope

-5-1/7-1 = -6/6= -1

y-y1 = slope(x-x1) // equation formula

y-1=-1(x-1)

y = -1x + 1 +1

y = -1x+2

Answer:

area of ΔABC = 48 cm²

Step-by-step explanation:

We have been provided with height of 6 cm and have to find base.

using Pythagoras theorem:

a² + b² = c²

a² + 6² = 10²

a² = 100 -36

a² = 64

a = √64

a = 8

Area of both triangles:

[tex]\frac{1}{2}[/tex] * base * height

[tex]\frac{1}{2}[/tex] * 8 * 6

24 cm²

area of both triangles: 24 cm² * 2 = 48 cm²

Apply Pythagorean theorem

[tex]\\ \tt\hookrightarrow AN^2=10^2-6^2[/tex]

[tex]\\ \tt\hookrightarrow AN^2=8^2[/tex]

[tex]\\ \tt\hookrightarrow AN=8cm[/tex]

Area

[tex]\\ \tt\hookrightarrow \dfrac{1}{2}bh[/tex]

[tex]\\ \tt\hookrightarrow \dfrac{1}{2}(16)(10)=8(10)=80cm^2[/tex]

Required area:-80/2=40cm^2

Answer:

Let the dryer cost x.

Then, the washer costs (x+87)

Together, they cost (x) + (x+87) = 787

2x+87 = 787

2x = 700 [subtract 97 from both sides]

x = 350 [divide both sides by 2]

The dryer cost $350.

Check: The washer cost $437. Together, they cost $787 [good to check, right?]

Answer:

= -(5c - 0.4d)^2

Step-by-step explanation:

4cd - 25c^2 - 0.16d^2

= 4cd - (5c)^2 - (0.4d)^2

= -[(5c)^2 -2*5*0.4cd + (0.4d)^2]
