Solve for x using the special right triangle

Answer:

C. [tex] 2\pi[/tex]

Step-by-step explanation:

Central angle [tex] ( \theta) = \frac{\pi}{2} = 90\degree[/tex]

Radius (r) = 4

[tex] l(\widehat{EF}) = \frac{ \theta}{360 \degree} \times 2\pi \: r \\ \\ = \frac{90 \degree}{360 \degree} \times 2\pi(4) \\ \\ = \frac{1}{4} \times 2\pi(4) \\ \\ l(\widehat{EF}) = 2\pi[/tex]

Answer: (The first number are the years and the second are the amount of Komodo's) (0, 0) (1, 4) (2, 20) (3, 100) (4, 500) (5, 2,500)

Step-by-step explanation:

If there are 4 Komodo's in the first year because that's when they moved in, then there would be zero in the 0 year.

If they keep multiplying their population by 5 each year then for every year, you would multiply the existing population of that year by 5

Starting at year 1 which is (1, 4)  multiply that by 5 to get 20 and so on to get the function.

I hope this helps!

Answer:

The locations of each irrational number are the following:

[tex]\sqrt{16}[/tex] - Point [tex]a[/tex]

[tex]\sqrt{27}[/tex] - Point [tex]b[/tex]

[tex]\sqrt{32}[/tex] - Point [tex]c[/tex]

Step-by-step explanation:

[tex]\sqrt{16}[/tex] is an irrational number that is also rational, since [tex]4^{2} = 16[/tex]. Then, [tex]\sqrt{16}[/tex] must be point [tex]a[/tex].

Both [tex]\sqrt{27}[/tex] and [tex]\sqrt{32}[/tex] are greater than [tex]\sqrt{25} = 5[/tex] and less than [tex]\sqrt{36} = 6[/tex]. Then, both are between 5 and 6. Since [tex]\sqrt{27} < \sqrt{32}[/tex], [tex]\sqrt{27}[/tex] must be point [tex]b[/tex] and [tex]\sqrt{32}[/tex] must be point [tex]c[/tex].

Answer:

90 mi/h

Step-by-step explanation:

Calculate speed, distance, or time using the formula d = st, distance equals speed times time. The Speed Distance Time Calculator can solve for the unknown sdt value given two known values.

Time can be entered or solved for in units of seconds (s), minutes (min), hours (hr), or hours and minutes and seconds (hh:mm:ss).  

To solve for distance use the formula for distance d = st, or distance equals speed times time.

distance = speed x time

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

distance = rate x time

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

time = distance/speed

Answer:

  x = -6

Step-by-step explanation:

The three marked angles total 180°, the number of degrees in a semicircle.

  (x +51) +65 +70 = 180

  x = 180 -186 = -6 . . . . . . . . subtract 186 and simplify

The value of x is -6.

Answer:

Sam is incorrect because you would not add the two times together. Hence there being 2 people working it would take you guys less time. You would actually subtract the times to get 5 minutes

Step-by-step explanation:

Answer:

Sam 's thinking is incorrect.

Step-by-step explanation:

Because If Sam takes 10 minutes to paint 25 square feet, then 5 minutes will be paint 12.5 sf... So if 15 minutes will paint 37.5 square feet. (by Sam)

---For me: if 5 mutes to paint 25 square feet.--->10 minutes will be 50 sf---> then 15 minutes will paint 75 square feet...

So If Same and I paint together will be 12.5 + 75 = 112.5 square feet
---Not 50 square feet...

What Sam says is incorrect....He can't add times together., that' s wrong.

Answer:

63 cm

Step-by-step explanation:

VZ = 42cm

ZX = 21

42/2= 21

What is 42 + 21 ?

There you go, you have your answer!

VX = 63cm

Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

If Z is the centroid of the triangle VWY

VZ = ZX

VX = VZ + ZX

The value of VX is 84 cm.

Option D is the correct answer.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Point Z is a centroid of the triangle VWY.

VZ = 42 cm

Now,

Centroid means,

VZ = 42 cm

VZ = ZX

VX = VZ + ZX

VX = 42 + 42 = 84 cm

Thus,

The value of VX is 84 cm.

Option D is the correct answer.

A. Linear

Step-by-step explanation:

The equation ([tex]t(x)=x+5[/tex]) is a linear equation. As per its definition, a linear equation is an equation where all terms are to the first degree, meaning that none of the terms have an exponent. The equation, ([tex]t(x)=x+5[/tex]) falls under this category, as none of its terms has an exponent, therefore, the equation is a linear equation.

The area of 1 slice is of 19 square inches.

Step-by-step explanation:

Area of a circle:

The area of a circle of radius r is given by:

[tex]A = \pi r^2[/tex]

A large pizza has a radius of 7 in.

So its area of the pizza, in square inches, is of:

[tex]A = \pi(7)^2 = 49\pi = 49*3.14 = 153.86[/tex]

The pizza is cut into 8 slices of equal size. What is the area of 1 slice, rounded to the nearest whole number?

Area of the pizza divided by 8. So

153.86/8 = 19.2

Rounding to the nearest whole number, the area of 1 slice is of 19 square inches.

Step-by-step explanation:

Answer:

a) = x1`-x2`/ Sp √ ( 1/n₁ + 1/n₂)

b)  it is assumed that the population standard deviations are known (which is sometimes met and sometimes not known).

c) The Confidence interval = [ 19131.77, 36868.23]

Step-by-step explanation:

Part a:

The 99% confidence interval for the difference between the average salaries of male and female neurologists is given by

(x1`-x2`) ±t∝/2(υ)* √ ( Sp²/n₁ + Sp²/n₂)

= x1`-x2`/ Sp √ ( 1/n₁ + 1/n₂)

where Sp ²= s₁² ( n1-1) + s₂²(n2-1) /(n1-1) + (n2-1)

Part B:

1) the sample should be normally distributed

2) it is assumed that the population standard deviations are known (which is sometimes met and sometimes not known).

Part C:

Calculations

1) H0: μ₁=μ₂ against the claim Ha: μ₁ ≠μ₂

2)The test statistic is

t= x1`-x2`/ √ ( Sp²/n₁ + Sp²/n₂)

where

Sp ²= s₁² ( n1-1) + s₂²(n2-1) /(n1-1) + (n2-1)

= 15,000²(17) + 22,000²(22) / 37

Sp ²= 103378640

3) D.f = n1+n2-2 =21+18-2 = 37

4) for 2 tailed test the critical value of t is obtained by

t≥ t∝/2 ( d.f)=t≥ t0.005 (37)= ±2.7154= ± 2.72

5) Putting the values

(x1`-x2`) ±t∝/2(υ)* √ ( sp²/n₁ + sp²/n₂)

28000 ± (2.72 * 3265.89)

=[ 19131.77, 36868.23].

The Confidence interval = [ 19131.77, 36868.23]
