Find the 2nd and 3rd term of the sequence 1, ___, ___, –11, –15, ...

Answer:

where is the figure? to calculate the surface area

Answer:

assuming that you want us to add them together here's the answer i got-

5y²−3y+3

Step-by-step explanation:

let us simplify step-by-step-

4y²−2y−5+y²(−y)+8

= 4y²+(−2y)+(−5)+y²+(−y)+8

combining like terms-

=4y²+−2y+−5+-y²+−y+8

=(4y²+y²)+(−2y+−y)+(−5+8)

=5y²+−3y+3

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Answer:

[tex]VW = 50[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find VW

To find VW, we make use of the following equivalent ratios.

[tex]YX : XW = ZX : XV[/tex]

Where:

[tex]YX = ZX - ZY = 42 - 28 = 14[/tex]

[tex]XV = XW + VW = 25 + VW[/tex]

So, we have:

[tex]14 : 25 = 42 : 25 + VW[/tex]

Express as fraction

[tex]\frac{14 }{ 25 }= \frac{42 }{ 25 + VW}[/tex]

Divide both sides by 14

[tex]\frac{1}{ 25 }= \frac{3}{ 25 + VW}[/tex]

Cross multiply

[tex](25 + VW) * 1 = 3 * 25[/tex]

[tex]25 + VW = 75[/tex]

Solve for VW

[tex]VW = 75 -25[/tex]

[tex]VW = 50[/tex]

Answer:

Yes, they are proportional

Step-by-step explanation:

First, simplify each fraction

30/80 can be simplified by dividing each number by 10

30/80

= 3/8

24/64 can be simplified by dividing each number by 8

24/64

= 3/8

So, each fraction will simplify to 3/8, meaning that they are proportional.

Step-by-step explanation: Well it took me 40 mins to get the answer and yes i know it shouldn't take that long but for a freshmanbut wow that was hard  , well 11 x 8 = 88 and 5 x 8 = 40 add that up 128 and for the 2nd question 11x 11= 121 then 5x 12= 60 and when you add it up you got 181 so what would the main numbers be that you used for both problems? it would be 11 for one  rose  and 5  for one shrubs. thanks for wasting my time on a hard question that took me 40 mins to answer

Answer:

The first blank is 9  for 9 cucumbers

The second blank is 8 dollars

Step-by-step explanation:

We can use ratios to solve

3 cucumbers           x cucumbers

--------------------- = ----------------------

2 dollars                   6 dollars

Using cross products

3*6 = 2x

18 = 2x

Divide by 2

18/2 = 2x/2

9 =x

We need 9 cucumbers

For the third row

3 cucumbers           12 cucumbers

--------------------- = ----------------------

2 dollars                   y dollars

Using cross products

3*y = 2*12

3y = 24

Divide by 3

3y/3 = 24/3

y = 8

We need 8 dollars

Step-by-step explanation:

If you would multiply out the negative you would get -3/2

Answer:

The 95% t-confidence interval for the difference in mean is approximately (-2.61, 1.16), therefore, there is not enough statistical evidence to show that there is a change in waiting time, therefore;

The change in the call waiting time is not statistically significant

Step-by-step explanation:

The given call waiting times are;

24.16, 20.17, 14.60, 19.79, 20.02, 14.60, 21.84, 21.45, 16.23, 19.60, 17.64, 16.53, 17.93, 22.81, 18.05, 16.36, 15.16, 19.24, 18.84, 20.77

19.81, 18.39, 24.34, 22.63, 20.20, 23.35, 16.21, 21.73, 17.18, 18.98, 19.35, 18.41, 20.57, 13.00, 17.25, 21.32, 23.29, 22.09, 12.88, 19.27

From the data we have;

The mean waiting time before the downsize, [tex]\overline x_1[/tex] = 18.7895

The mean waiting time before the downsize, s₁ = 2.705152

The sample size for the before the downsize, n₁ = 20

The mean waiting time after the downsize, [tex]\overline x_2[/tex] = 19.5125

The mean waiting time after the downsize, s₂ = 3.155945

The sample size for the after the downsize, n₂ = 20

The degrees of freedom, df = n₁ + n₂ - 2 = 20 + 20  - 2 = 38

df = 38

At 95% significance level, using a graphing calculator, we have; [tex]t_{\alpha /2}[/tex] = ±2.026192

The t-confidence interval is given as follows;

[tex]\left (\bar{x}_{1}- \bar{x}_{2} \right )\pm t_{\alpha /2}\sqrt{\dfrac{s_{1}^{2}}{n_{1}}+\dfrac{s_{2}^{2}}{n_{2}}}[/tex]

Therefore;

[tex]\left (18.7895- 19.5152 \right )\pm 2.026192 \times \sqrt{\dfrac{2.705152^{2}}{20}+\dfrac{3.155945^2}{20}}[/tex]

(18.7895 - 19.5125) - 2.026192*(2.705152²/20 + 3.155945²/20)^(0.5)

The 95% CI = -2.6063 < μ₂ - μ₁ < 1.16025996668

By approximation, we have;

The 95% CI = -2.61 < μ₂ - μ₁ < 1.16

Given that the 95% confidence interval ranges from a positive to a negative value, we are 95% sure that the confidence interval includes '0', therefore, there is sufficient evidence that there is no difference between the two means, and the change in call waiting time is not statistically significant.

Answer:

Answer: 2, 1.5 , -0.75

(b) [tex]4x-3y-10=0[/tex]

Step-by-step explanation:

Given

line is [tex]3x+4y-6=0[/tex]

Converting it into intercept form

[tex]\Rightarrow 3x+4y=6\\\\\Rightarrow \dfrac{3x}{6}+\dfrac{4y}{6}=\dfrac{6}{6}\\\\\Rightarrow \dfrac{x}{2}+\dfrac{y}{1.5}=1[/tex]

So, the x-intercept is [tex]2[/tex] and y-intercept is [tex]1.5[/tex]

The slope is given by

[tex]-\dfrac{\frac{1}{2}}{\frac{1}{1.5}}=-0.75[/tex]

(b) the line perpendicular to the above line and passing through [tex](1,-2)[/tex]

The slope of the required line

[tex]m=-\dfrac{1}{-0.75}\\\\m=\dfrac{4}{3}[/tex]

Equation of the line is given by

[tex]\Rightarrow \dfrac{y-(-2)}{x-1}=\dfrac{4}{3}\\\\\Rightarrow 3y+6=4x-4\\\Rightarrow 4x-3y-10=0[/tex]

Answer:

I only know the first question, If you leave that money for 1 year it would equal $480 basically,  $300 x 1.6 = $480.

Step-by-step explanation:

The required amount in your account after 2 years will be $337.08.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Here,
If you deposit $300 in an account with a 6% interest rate, the amount in your account after 1 year can be calculated as follows:

Find the interest earned after one year:

Interest earned = (6/100) x 300 = $18

Add the interest earned to the original amount:

Total amount after 1 year = $300 + $18 = $318

Therefore, the amount in your account after 1 year will be $318.

If you leave this money in the account for another year, the amount in your account after 2 years can be calculated as follows:

Find the interest earned after two years:

Interest earned in year 1 = $18

Interest earned in year 2 = (6/100) x $318 = $19.08

Add the interest earned to the original amount and the interest earned in year 1:

Total amount after 2 years = $300 + $18 + $19.08 = $337.08

Therefore, the amount in your account after 2 years will be $337.08.

Answer:

each tangent is 20.785 ft long

Step-by-step explanation:

since the tangent forms a right angle with the radius, and a line from P to O bisects the 60° angle:

tan 30° = 12/x

0.5774 = 12/x

0.5774x = 12

x = 20.785 ft

Answer:

Step-by-step explanation:

So first we distribute -12 to 6 making that -72 then we distribute the -12 to the 4 making that -48.

So we have -72+-48 = -72 - 48 = -120

It is important to know that the answer is not -120 (10)(-12) = -120

because that is not the distributive property.

Answer:

2x² + 7x - 4

Step-by-step explanation:

(2x + 1)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(x + 4) - 1 (x + 4) ← distribute parenthesis

2x² + 8x - x - 4 ← collect like terms

= 2x² + 7x - 4
