Answers

Answer 1

Answer:

2x3+x2−x+1x

Step-by-step explanation:

Let's solve for f.

fx=2x3+x2−x+1

Step 1: Divide both sides by x.

fx=2x3+x2−x+1x

fx=2x3+x2−x1x

Answer:

  -1.2338

Step-by-step explanation:

The graph shows the one real root is about -1.234. The Newton's method iterator is ...

  new x = x - f(x)/f'(x) . . . . . where f'(x) is the derivative of f(x)

Many graphing calculators provide a derivative function, so the iteration equation can be evaluated more or less directly by the calculator. In the attached, we have shown a table with three iterations of the root. After the second iteration, the root is good to 4 decimal places.

  x ≈ -1.2338

Step-by-step explanation:

Many ancient tombs were cut from limestone rock that contained uranium. Since most such tombs are not​ well-ventilated, they may contain radon gas. In one​ study, the radon levels in a sample of 12 tombs in a particular region were measured in becquerels per cubic meter (Bq/m3). For this​ data, assume that x(over-bar)= 3,469 Bq/m3 and s= 1,135 Bq/m3. Use this information to​ estimate, with 95% confidence, the mean level of radon exposure in tombs in the region. Interpret the resulting interval.

(2746.868 , 4191.132)

Step-by-step explanation:

Step(i):-

Given sample size 'n'= 12

Mean of the sample  x⁻ = 3,469

and standard deviation of the sample 's' = 1,135

95% confidence intervals are determined by

[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} +t_{0.05} \frac{S}{\sqrt{n} } )[/tex]

Degrees of freedom = n-1 = 12-1= 11

Step(ii):-

95% confidence intervals are determined by

[tex](3469- 2.201 \frac{1135}{\sqrt{12} } , 3469+2.201\frac{1135}{\sqrt{12} } )[/tex]

Answer:

The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2) D

Step-by-step explanation:

To solve this type of question, Form the equation of the line and substitute the x-coordinate of each ordered pair to find y, if the value of y equal to the value of the y-coordinate of the point, then the point is on the line

The form of the linear equation is y = m x + b, where

m is the slope of the lineb is the y-intercept (value y at x = 0The rule of the slope of the line that passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]

From the given figure

∵ The line passes through points (-4, 0) and (0, 4)

x1 = -4 and y1 = 0

x2 = 0 and y2 = 4

→ Substitute them in the rule above

∵ m = [tex]\frac{4-0}{0--4}[/tex] = [tex]\frac{4}{0+4}[/tex] = [tex]\frac{4}{4}[/tex]

m = 1

∵ b is the value of y at x = 0

∵ y = 4 at x = 0

b = 4

→ Substitute the values of m and b in the form of the equation above

∴ y = 1(x) + 4

y = x + 4 ⇒ equation of the given line

Let us check every group

∵ The ordered pairs are (7, 3), (6, 2), (2, -2)

∵ y = x + 4

∵ x = 7

∵ y = 7 + 4 = 11

∵ y-coordinate = 3

∴ Point (7, 3) doesn't lie on the line

∵ The ordered pairs are (5, 1), (3, 7), (2, 6)

∵ x = 5

∴ y = 5 + 4 = 9

∵ y-coordinate = 1

∴ Point (5, 1) doesn't lie on the line

∵ The ordered pairs are (3, 7), (2, 6), (2, 2)

∵ x = 3

∴ y = 3 + 4 = 7

∵ y-coordinate = 7

∴ Point (3, 7) lies on the line

∵ x = 2

∴ y = 2 + 4 = 6

∵ y-coordinate = 6

∴ Point (2, 6) lies on the line

∵ x = 2

∴ y = 6

∵ y-coordinate = 2

∴ Point (2, 2) doesn't lie on the line

The ordered pairs are (3, 7), (2, 6), (-2, 2)

∵ x = 3

∴ y = 3 + 4 = 7

∵ y-coordinate = 7

Point (3, 7) lies on the line

∵ x = 2

∴ y = 2 + 4 = 6

∵ y-coordinate = 6

Point (2, 6) lies on the line

∵ x = -2

∴ y = -2 + 4 = 2

∵ y-coordinate = 2

Point (-2, 2) lies on the line

∵ The three ordered pairs lie on the line

The group of all ordered pairs lie on the line is (3, 7), (2, 6), (-2, 2)

∵ The ordered pairs are (1, 5), (-6, 2), (-7, -3)

∵ x = 1

∴ y = 1 + 4 = 5

∵ y-coordinate = 5

∴ Point (1, 5) lies on the line

∵ x = -6

∴ y = -6 + 4 = -2

∵ y-coordinate = 2

∴ Point (-6, 2) doesn't lie on the line

find the gretest number which devded by 181 and 236 leave a remainder of 5 in each case​

Answers

Answer:

The greatest number is 11

Step-by-step explanation:

Given

Dividends: 181 and 236

Remainder: 5

Required

Determine a divisor that satisfies the above condition

Let the required divisor be represented with x.

Since a remainder of 5 is expected, then x can divide (181 - 5) and (236 - 5) without remainders.

So, we have:

[tex]181 - 5 = 176[/tex]

[tex]236 - 5 = 231[/tex]

Next, we calculate the GCF of 176 and 231

[tex]176 = 2 * 2 * 2 * 2 * 11[/tex]

[tex]231 = 3 * 7 * 11[/tex]

The greatest common factor, GCT is:

[tex]GCF = 11[/tex]

Hence, the required divisor is 11

A dress regularly sells for $135. The sale price is $93. Find the percent decrease of the sale price from the regular
price.
31.1%
221.4%
45.2%
68.9%

Answers

Answer:

32% Decrease

Step-by-step explanation:

93 = x * 135 (divide both sides by 135 to get X alone.)

x=0.68 - Repeated (This tells us that it was paid 68% of the OG price.)

1 - 0.68 = 0.32 (We need to subtract the percent  paid from the OG price to find the percent discount.)

The percent decrease was 32% off.
