\(( x + 1)(x - 1)\)
what's the answer!!!!​

Answer:

∠1 = 40

Step-by-step explanation:

So due to the alternate interior angles theorem, angle 1 and angle 2 equal each other so:

2x + 20 = 3x + 10

subtract 2x from both sides

20 = x + 10

subtract 10 from both sides

10 = x

Now input 10 into the equation

2(10) + 20

20 + 20

Complete question:

Corporate spending on equipment, structures and intellectual property, decreased an annualized 2.2 percent after a 3.4 percent fall in the first quarter. Outlays for equipment dropped for the fourth time in the past five quarters. Spending on structures -- everything from factories to shops to oil rigs -- have increased in just one quarter since the end of 2014. Inventories and the trade gap are two of the most volatile components in GDP calculations. To get a better sense of demand in the U.S., economists look at final sales to domestic purchasers, or GDP excluding inventories and net exports. That measure increased 2.1 percent last quarter after a 1.2 percent gain. Also holding back economic growth in the second quarter was a decrease in residential investment, which fell at a 6.1 percent pace. That was the most since the third quarter of 2010 and marked the first decrease in two years. Government spending also shrank last quarter, declining 0.9 percent, the most in more than two years as outlays for the military fell. States and municipalities also cut back. The GDP report also showed price pressures remain limited. A measure of inflation, which is tied to consumer spending and strips out food and energy costs, climbed at a 1.7 percent annualized pace compared with 2.1 percent in the prior quarter. Fed policy makers, who left interest rates unchanged this week, said risks to the U.S. outlook have “diminished” and the labor market is getting tighter, suggesting conditions are turning more favorable for an increase in borrowing costs.

Answer:

Left box:  1/2n

Right box = 2n - 22

Step-by-step explanation:

Since we want one-half the number and n represents the unknown number, we have 1/2n on the left-hand side of the equation.

Thus, you want to put 1/2n in box on the left.

Twice the number and 22 less than this is given by:  y: 2n - 22 less than this means we subtract.  Thus, we have 2n - 22 as the numerator on the right hand side of the equation.

Thus, you want to put 2n - 22 in the box on the right.

Given:

The equation is:

\(y=2x+1\)

To find:

The y-coordinates for the ordered pairs (0, _), (-1, _) and (1, _)for this equation.

Solution:

We have,

\(y=2x+1\)

For \(x=0\),

\(y=2(0)+1\)

\(y=0+1\)

\(y=1\)

For \(x=-1\),

\(y=2(-1)+1\)

\(y=-2+1\)

\(y=-1\)

For \(x=1\),

\(y=2(1)+1\)

\(y=2+1\)

\(y=3\)

Therefore, the complete ordered pairs are (0,1), (-1, -1) and (1,3). Plot these points on a coordinates plane and connect them by a straight line as shown in the below figure.

The average rate of change of f(x) over the interval [-3, 2] is 8.The average rate of change of f(x) over the interval [-3, 2] can be calculated by finding the difference in the values of f(x) at the endpoints and dividing it by the difference in x-values.

To find the average rate of change of f(x) over the interval [-3, 2], we need to calculate the difference in the values of f(x) at the endpoints of the interval and divide it by the difference in x-values. The value of f(x) at x = -3 is 36, and the value of f(x) at x = 2 is 24. The difference in f(x) is 24 - 36 = -12.

The difference in x-values is 2 - (-3) = 5.

To calculate the average rate of change, we divide the difference in f(x) by the difference in x-values:

Average rate of change = (-12) / 5 = -2.4

However, none of the given answer choices match this result. Therefore, it appears that there might be an error in the provided table of values or answer choices.

Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

We need approximately 10 deposits to reach a balance of $31,300 four years after the last deposit which is compounded semi-annually.

To solve this problem, we can use the formula for the future value of an annuity:

\(FV = P * ((1 + r)^n - 1) / r\)

Where:

FV is the future value of the annuity

P is the periodic payment or deposit amount

r is the interest rate per period

n is the number of periods

In this case, the deposit amount is $726.56, the interest rate is 6.45% compounded semi-annually, and the future value is $31,300. We need to find the number of deposits (n).

We can rearrange the formula and solve for n:

n = log((FV * r) / (P * r + FV)) / log(1 + r)

Substituting the given values:

n = log((31,300 * 0.03225) / (726.56 * 0.03225 + 31,300)) / log(1 + 0.03225)

Using a calculator or software, we find that n ≈ 9.989.

Therefore, we need approximately 10 deposits to reach a balance of $31,300 four years after the last deposit.

The number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles is 244 minutes.

When the distribution is normal, we use the z-score formula.

In a set with mean µ and standard deviation σ , the z-score of a measure X is given by:

Z = (X – µ) / σ

The Z-score shows how many standard deviations the measure is from the mean. After finding the Z-score, need to look at the z-score table and discover the p-value associated with the z-score. This p-value is the probability that the value of the measure is smaller than X, means, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

So, in this case, given that:

µ = 249, σ = 20

The number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles:

100 – 80 = 20th percentile, which is X when Z has a p-value of 0.2. So, X when Z = –0.253.

Now, put all the values into the formula:

Z = (X – µ) / σ

–0.253 = (X – 249) / 20

X – 249 = –0.253 * 20

X = 244

Hence, the candle burns for 244 minutes.

Step-by-step explanation:

Anika is a smart shopper who loves to sew her own clothes. She has a big event coming up: her sister's wedding! She wants to make some beautiful dresses for herself and her family. She finds a nice cloth that costs ₹210 for 5 metres. How much will she pay for different lengths of cloth? Let's see:

We can use a simple equation to calculate the cost of the cloth. The equation is:

y = 42x

where y is the cost in rupees and x is the length in metres. Why 42? Because 210 divided by 5 is 42. Easy peasy!

Now let's plug in some values for x and see what we get.

If x = 2, then y = 42 x 2 = 84. So Anika will pay ₹84 for 2 metres of cloth.

If x = 4, then y = 42 x 4 = 168. So Anika will pay ₹168 for 4 metres of cloth.

If x = 10, then y = 42 x 10 = 420. So Anika will pay ₹420 for 10 metres of cloth.

If x = 13, then y = 42 x 13 = 546. So Anika will pay ₹546 for 13 metres of cloth.

| Length (metres) | Cost (rupees) |

| --------------- | ------------- |

| 2               | 84            |

| 4               | 168           |

| 10              | 420           |

| 13              | 546           |

Anika is happy with her calculations. She decides to buy 10 metres of cloth and make three dresses: one for herself, one for her sister, and one for her mother. She will have some cloth left over for accessories. She can't wait to show off her creations at the wedding!

The total surface area of a cuboid is 2( lw + wh + wl) and the lateral surface area is 2(l + w)×h.

Given, The width of the box is seven inches less than the height.

Assuming the width to be 'w' hence the height(h) = w + 7 and has a length of 24 inches with a volume of 2880 cubic inches.

We know the volume(V) of a cuboid is l×w×h.

Therefore,

24×w×(w + 7) = 2880.

24w(w + 7) = 2880.

24w² + 168w = 2880.

6w² + 42w = 720.

w² + 7w = 120.

w² + 7w - 120 = 0.

w² + 15w - 8w - 120 = 0.

w(w + 15) - 8(w + 15) = 0.
