Write the equation of the circle graphed below.
Answers
Answer:
(x + 2)² + (y + 2)² = 0.75²
Step-by-step explanation:
Standard form
(x - h)² + (y - k)² = r²
the center is (h, k) = (-2, -2)
the radius is r = 0.75
(x + 2)² + (y + 2)² = 0.75²
Answer:
(x + 2)^2 + (y + 2)^2 = 0.5625
Step-by-step explanation:
By looking at the graph, we can see the center of the circle is (-2, -2) and by counting the squares, the radius is 0.75.
The standard form of a circle equation is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
We can substitute our values in to get:
(x + 2)^2 + (y + 2)^2 = 0.5625

Find the area of this
irregular figure.
9 ft
[ ? ] square feet
8 ft
15 ft
26 ft
Answers
Answer:
426 ft^2.
Step-by-step explanation:
It area = area of the rectangle + area of the triangle
= 15 * 26 + 1/2 * 8 * 9
= 390 + 1/2*8*9
= 390 + 36
= 426 ft^2.
The area of the figure given is 426 ft^2.
How to find the surface area of some object?Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object.
Supposing that there is no direct formula available for deriving the area, we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly.
Area = Area of the rectangle + Area of the triangle
Area = 15 * 26 + 1/2 * 8 * 9
Area = 390 + 1/2*8*9
Area = 390 + 36
Area = 426 ft^2.
Therefore, the area of the figure given is 426 ft^2.

a 440m long road is being repaired at the end of 3 days the workers had repaired 3/4 of the road what length of the road is left unrepaired
Answers
THE ANSWER IS 110 m
Workers had repaired 3/4 of the road
it means3/4×440 is been repaired
length of repaired road is 3×110 = 330m
length of unrepaired road = Length of to road - length of repaired road
i.e. = 440-330 = 110m
Jennifer age 18 initially invested $1000 at 8% interest how old would she be when the account is $128,000
Answers
Answer:
2,304 years old
Step-by-step explanation:
Given: Jennifer age = 18, Invested = $1000 at 8% interest
To find: How old would she be when the account is $128,000?
Wrong solution
Solution: To figure out how old she will be when her account is $128,000, simply find the difference between her current account value by her current age, by dividing. Then multiply the result by the future account value.
Step 1: [tex]\frac{1000}{18} = 55.5555555556[/tex]
Rounding, that is; 55.56
Step 2: Now, multiply the result by the future account value.
[tex]55.56[/tex] × [tex]128000 = 7111680[/tex]
Correct solution
Solution: To find out how old she will be when her account is $128,000, set up a fraction;
[tex]\frac{1000}{8} = \frac{12800}{x}[/tex]
Step 1: Divide the numbers
[tex]\frac{1000}{8} = \frac{128000}{x} \\\\\frac{500}{9} = \frac{128000}{x}[/tex]
Step 2: Multiply all terms by the same value to eliminate fraction denominators
[tex]\frac{500}{9} = \frac{128000}{x} \\\\x * \frac{500}{9} = x * \frac{128000}{x}[/tex]
Step 3: Cancel multiplied terms that are in the denominator
[tex]x *\frac{500}{9} = x * \frac{128000}{x} \\\\x * \frac{500}{9} = 128000[/tex]
Step 4: Re-order terms so constants are on the left
[tex]x * \frac{500}{9} = 128000\\\\\frac{500}{9} x= 128000[/tex]
Step 5: Combine multiplied terms into a single fraction
[tex]\frac{500}{9} x = 128000\\\\\frac{500x}{9} = 128000[/tex]
Step 6: Multiply all terms by the same value to eliminate fraction denominators
[tex]\frac{500x}{9} = 128000\\\\9 * \frac{500x}{9} = 9 * 128000[/tex]
Step 7: Cancel multiplied terms that are in the denominator
[tex]9 * \frac{500x}{9} = 9 * 128000\\500

Find the equation of a line perpendicular to 4x - 5y = -1 that contains the point (5, -4)
Answers
Answer:
y = -5/4x + 2 1/4
Step-by-step explanation:
you would start by changing the equation to point intercept form
4x + 1 = 5y
4/5y + 1/5 = y
then you fill in the points and change the slope to -5/4 (reciprocal and opposite sign)
-4 = -5/4(5) + b
-4 = -6.25 + b
2.25 = b

A food scientist takes a random sample of 25 cereals in order to test the claim that the mean fiber content is less than 2.5 grams. The graphs of the data and two types of hypothesis test output are provided below. Determine which output should be used and state the conclusion of this test at the 5% significance level.
Answers
Answer:
Choice A: there is insufficient evidence to conclude that the mean for the fiber content is less than 2.5 gms.
Step-by-step explanation:
From the graphs given the more appropriate is one sample t- test
One sample t- test is used and the results are
Hypothesis Test Fiber
Sample Mean 2.62
Sample St. Dev 3.492
Degrees of Freedom 24
t- test statistic 0.1718
p- value 0.5675
the critical region for this test at ∝= 0.05 is t < -1.711
There is not enough evidence to reject the null hypothesis.
Since the calculated t= 0.1718 does not fall in the critical region the null hypothesis is accepted that the mean fiber content is not less than 2.5 grams.T
