Answer:

The next two terms for the geometric sequence are 250 and - 1,250

Step-by-step explanation:

1. Let's find the next two terms for the geometric sequence which first three terms are as follows:

- 2, 10, - 50.....

Aₓ = Aₓ₋₁ * - 5 ; A₁ = - 2

A₁ = - 2

A₂ = A₁ * - 5 = -2 * - 5 = 10

A₃ = A₂ * - 5 = 10 * - 5 = - 50

A₄ = A₃ * - 5 = - 50 * - 5 = 250

A₅ = A₄ * - 5 = 250 * - 5 = - 1,250

The next two terms for the geometric sequence are 250 and - 1,250

Part 6) The distance between their houses is [tex]=4\sqrt{2}\ mi[/tex]

Part 7) [tex]234.31\ mi[/tex]

Part 8) 120 feet of wire is required

Step-by-step explanation:

Part 1) we know that

To find the length of the hypotenuse in a right triangle apply the Pythagorean Theorem

[tex]c^2=a^2+b^2[/tex]

where

c is the hypotenuse (the greater side)

a and b are the legs

we have

[tex]a=11\ cm\\b=5\ cm[/tex]

substitute

[tex]c^2=11^2+5^2[/tex]

[tex]c^2=146[/tex]

[tex]c=\sqrt{146}\ cm[/tex]

Part 2) we know that

To find the length of the hypotenuse in a right triangle apply the Pythagorean Theorem

[tex]c^2=a^2+b^2[/tex]

where

c is the hypotenuse (the greater side)

a and b are the legs

we have

[tex]a=8\ in\\b=8\ in[/tex]

substitute

[tex]c^2=8^2+8^2[/tex]

[tex]c^2=128[/tex]

[tex]c=\sqrt{128}\ in[/tex]

simplify

[tex]c=8\sqrt{2}\ in[/tex]

Part 3) we know that

To find the length of the diagonal in a rectangle apply the Pythagorean Theorem

[tex]d^2=b^2+h^2[/tex]

where

d is the diagonal of rectangle

b and h are the base and the height of rectangle

we have

[tex]b=15\ cm\\hb=6\ cm[/tex]

substitute

[tex]d^2=15^2+6^2[/tex]

[tex]d^2=261[/tex]

[tex]d=\sqrt{261}\ cm[/tex]

simplify

[tex]d=3\sqrt{29}\ cm[/tex]

Part 4) we know that

To find the length of the diagonal of a computer monitor apply the Pythagorean Theorem

[tex]d^2=w^2+h^2[/tex]

[tex]d^2=12^2+9^2[/tex]

[tex]d^2=225[/tex]

[tex]d=\sqrt{225}\ in[/tex]

simplify

[tex]d=15\ in[/tex]

Part 5) we know that

To find out the length of the ramp apply the Pythagorean Theorem

[tex]L^2=x^2+y^2[/tex]

where

L is the length of the ramp

x  is the horizontal distance of the ramp

y  is the vertical distance of the ramp

we have

[tex]x=10\ ft\\y=3.5\ ft[/tex]

substitute

[tex]L^2=10^2+3.5y^2[/tex]

[tex]L^2=112.25[/tex]

[tex]L=10.59\ ft[/tex]

Part 6) we know that

To find the distance between their houses apply the Pythagorean Theorem

[tex]c^2=a^2+b^2[/tex]

where

substitute

[tex]c^2=4^2+4^2[/tex]

[tex]c^2=32[/tex]

[tex]c=4\sqrt{2}\ mi[/tex]

Part 7) we know that

The speed is equal to divide the distance by the time

[tex]speed=distance/time[/tex]

so

the distance is equal to multiply the speed by the time

[tex]distance=speed*time[/tex]

First train

speed=60 mph

time=3 hours

distance=60(3)=180 miles

Second train

speed=50 mph

time=3 hours

distance=50(3)=150 miles

To find out how far apart are the trains at the end of 3 hours apply the Pythagorean Theorem

[tex]c^2=a^2+b^2[/tex]

where

c is the hypotenuse (distance between the trains)

a and b are the legs

we have

[tex]a=180\ mi\\b=150\ mi[/tex]

substitute

[tex]c^2=180^2+150^2[/tex]

[tex]c^2=54,900[/tex]

[tex]c=234.31\ mi[/tex]

Part 8)  we know that

For one tree is needed three wire

To find out the length of one wire apply the Pythagorean Theorem

[tex]c^2=a^2+b^2[/tex]

where

c is the hypotenuse (length of one wire)

a and b are the distance above the ground and the distance from the base

we have

[tex]a=3\ ft\\b=4\ ft[/tex]

substitute

[tex]c^2=3^2+4^2[/tex]

[tex]c^2=25[/tex]

[tex]c=5\ ft[/tex]

so

For one tree is required ----> (5)3=15 ft

therefore

For 8 trees is required

Multiply by 8

15(8)=120 ft

Answer:

The speed of the boat in still water is 12 km/hour.

Step-by-step explanation:

Given:

Boat goes 50 km downstream and 30 km upstream. The speed of the stream 3 km/hour.

Now, to find the speed of the boat in still water:

Let the speed of boat in still water be [tex]x km/hour[/tex].

The speed of the downstream be [tex]x+3[/tex]

And, the speed of the upstream be [tex]x-3[/tex]

And, now we find the time by putting the formula:

[tex]Time = \frac{Distance}{Rate}[/tex]

So, downstream time is:

[tex]downstream\ time = \frac{50}{x+3}[/tex]

So, upstream time is:

[tex]upstream\ time = \frac{30}{x-3}[/tex]

According to question:

Time upstream = Time downstream

[tex]\frac{30}{x-3} = \frac{50}{x+3}[/tex]

By cross multiplication:

[tex]30\times (x+3)= 50\times (x-3)[/tex]

[tex]30x+90=50x-150[/tex]

By taking variables in one side and taking numbers on the other side we get:

[tex]90+150=50x-30x[/tex]

[tex]240=20x[/tex]

Dividing both sides by 20 we get :

[tex]12=x[/tex]

Therefore, the speed of the boat in still water is 12 km/hour.

Answer

x = 50 mph (level rate)

x-30 = 20 mph (mountain rate)

Explain:

time = time

160/(x-30) = 400/x

160x = 400(x-30)

160x = 400x - 12000

-240x = -12000

Answer:

i think maybe 600k?

Step-by-step explanation:

To find out how much more interest is paid on a $195,000 home with a 20% down payment and a balance financed with a 30-year mortgage at 6% compared to 3.5%, one must calculate the total interest for each rate over the 30-year period and then compare the two totals.

To determine the difference in the amount of interest paid over the life of a 30-year mortgage because of different interest rates, we need to calculate the total interest for both scenarios. With a $195,000 home and a 20% down payment, the amount to be financed is $156,000 (since 20% of $195,000 is $39,000, and $195,000 - $39,000 = $156,000).

For the 6% mortgage rate, the monthly payment can be found using the formula for a fixed-rate mortgage, which is P[r(1+r)^n]/[(1+r)^n-1], where P is the principal ($156,000), r is the monthly interest rate (0.06/12), and n is the number of payments (360). Similarly, we calculate the monthly payment for the loan at 3.5% interest.

Once the monthly payments are determined, we can calculate the total payment over 30 years for each rate by multiplying the monthly payment by 360. The difference between the two total payments will give us the additional interest paid due to the higher interest rate.

Answer: Kremena needs to deposit $1,101 today to earn a total of $1,250 in 3 years at 4.5% simple interest rate

Step-by-step explanation:

Interest = Principal (P) × Rate (R) × Time (T)

Amount = Principal (P) + Interest

Amount = P + PRT

Amount = P (1 + RT)

1250 = P (1 + (0.045 × 3))

1250 = P (1 + 0.135)

1250 = P (1.135)

Principal = 1250 ÷ 1.135

Principal = approx. 1101

Final answer:

Kremena needs to deposit approximately $1,101 today at a simple interest rate of 4.5% to have $1,250 in 3 years.

Explanation:

To find out how much Kremena needs to deposit today to have her account worth $1,250 in 3 years at a simple interest rate of 4.5%, we use the simple interest formula:

I = P * r * t, where:

Kremena wants the final amount (A) to be $1,250. The final amount is the sum of the principal and the interest earned: A = P + I. Therefore, we rearrange the simple interest formula to calculate P:

P = (A - (I = A * r * t)) / (1 + r * t)

Here, I = A - P, which means:

P = A / (1 + r * t)

Plugging in the numbers:

P = $1,250 / (1 + 0.045 * 3)

P = $1,250 / 1.135

P ≈ $1,101

Therefore, Kremena must deposit approximately $1,101 today to have $1,250 in 3 years at a 4.5% simple interest rate.

We can use the points (2, -2) and (4, -1) to solve.

Slope formula: y2-y1/x2-x1

Answer:

[tex]\theta =2\pi k,\ \ k\in Z\ \\\text{or}\ \\\theta=-\dfrac{2\pi}{3}+2\pi k,\ \ k\in Z[/tex]

Step-by-step explanation:

Given:

[tex]\cos \theta-\sqrt{3}\sin \theta=1[/tex]

Divide this equation by 2:

[tex]\dfrac{1}{2}\cos \theta-\dfrac{\sqrt{3}}{2}\sin \theta=\dfrac{1}{2}[/tex]

Note that

[tex]\cos \dfrac{\pi }{3}=\dfrac{1}{2}\\ \\\sin \dfrac{\pi }{3}=\dfrac{\sqrt{3}}{2}[/tex]

So, the previous equation is

[tex]\cos \dfrac{\pi}{3}\cdot \cos \theta-\sin \dfrac{\pi}{3}\cdot \sin \theta=\dfrac{1}{2}[/tex]

Remind that

[tex]\cos x\cos y-\sin x\sin y=\cos (x+y),[/tex]

then

[tex]\cos \left(\dfrac{\pi}{3}+\theta\right)=\dfrac{1}{2}[/tex]

The solution of this equation is

[tex]\dfrac{\pi}{3}+\theta=\pm \arccos \dfrac{1}{2}+2\pi k,\ \ k\in Z\\ \\\dfrac{\pi}{3}+\theta=\pm \dfrac{\pi}{3}+2\pi k,\ \ k\in Z\\ \\\theta =2\pi k,\ \ k\in Z\ \text{or}\ \theta=-\dfrac{2\pi}{3}+2\pi k,\ \ k\in Z[/tex]

There are 152 men, 76 women and 38 children.

Step-by-step explanation:

Total persons = 266

Let,

Find square root:

Answer = 12

Answer:

250 students

Step-by-step explanation:

Another way of saying this is:

40% of all six-grade students are 100 of them.

So,

40% of total is equal to 100

We can translate this into an algebraic equation and solve for the total number of students.

Let total number of students be "t"

Also, note "of" means "multiplication" and "is" means "equal"

Lets translate word equation to algebraic:

"40% of total is equal to 100"

40% * t = 100

Converting percentage to decimal by dividing by 100, we have:

40% = 40/100 = 0.4

Now, we have:

0.4 * t = 100

We can now solve for t:

[tex]0.4 * t = 100\\t=\frac{100}{0.4}\\t=250[/tex]

Hence,

the total number of students is 250
