Circle B has a center at point (0, 2) and a point W on the circle at (3, 3). Which equation represents a line that is tangent to the circle and goes through the point W?
According to the given information, the equation represents a line that is tangent to the circle and goes through the point W is given by:
y = -x + 6.
What is the equation of the circle?The equation of a circle of center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In this problem, we have that the center is at point (0,2), hence:
[tex]x^2 + (y - 2)^2 = r^2[/tex]
It goes through point (3,3), hence:
[tex]3^2 + (3 - 2)^2 = r^2[/tex]
[tex]r^2 = 10[/tex]
Hence, the equation is:
[tex]x^2 + (y - 2)^2 = 10[/tex]
What is the equation of the tangent line at point W?It is given by:
[tex]y - y(0) = \frac{dy}{dx}|_{W}(x - x(0))[/tex]
Applying implicit differentiation, we have that:
[tex]2x + 2y\frac{dy}{dy} = 0[/tex]
[tex]\frac{dy}{dx} = -\frac{x}{y}[/tex]
Point W(3,3), hence:
[tex](x_0, y_0) = (3,3)[/tex]
[tex]\frac{dy}{dx} = -\frac{3}{3} = -1[/tex]
Hence the equation is:
y - 3 = -(x - 3).
y = -x + 6.

Answer
Find out the m∠p .
To prove
As in ΔDAB is a right triangle
Apply pythagorean theorem
Hypotenuse ² = Perpendicular ² + Base²
DB² = AB² + AD²
AB = 5 units
AD = 6 units
Put in the above formula
DB² = 5² + 6²
= 25 + 36
= 61
= 7.8 units (approx)
Now in ΔDCB is a right triangle .
By using the trignometric identity .
As DC = 4 units
DB = 7.8 units (approx)
Put all the values in the trignometric identity .
∠p = 59.15 ° (approx)
In circle F with m EFG = 48 and
EF = 15 units, find the length of arc EG.
Round to the nearest hundredth.
Answer:
12.57 units
Step-by-step explanation:
i put the explanation in the picture because i didnt know how to put it in here
The length of arc EG is 12.56 units.
What is an arc length of a circle?The arc length of a circle is the distance between two points on the curve of the circle.
We have,
Arc length = (angle/360) x (2πr)
Now,
From the circle,
EF = r = 15 units
m∠EFG = angle = 48
Substituting.
Arc length
= (angle/360) x (2πr)
= 48/360 x 2π x 15
= 12.56
Thus,
The length of arc EG is 12.56 units.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 72 N acts on a certain object, the acceleration of the object is 9m/s^{2} . If the acceleration of the object becomes 5 /ms2 , what is the force?
Answer:
40N
Step-by-step explanation:
F=ma
1st case: 72N = m(9m/s^2)
m = 72N/(9m/s^2)
2nd case: F = m(5m/s^2)
m = F/(5m/s^2)
Since the mass is the same:
72N/(9m/s^2) = F/(5m/s^2)
F = 72N/(9m/s^2)/(5m/s^2)
F = (5/9)(72N)
F = 40N

Answer:
9 fruit slushies; 6 cones
Step-by-step explanation:
Let f = number of fruit slushies.
Let c = number of cones.
c + f = 15

There are sto students in a school. If the number of boys and girls are in the ratio 4:3, find their numbers.
Answer:
number of boys = 320
number of girls = 240
Step-by-step explanation:
Total students in school = 560
Ratio of boys to girls = 4 : 3
Add the ratios together: 4 + 3 = 7
Divide the total by this number: 560 ÷ 7 = 80
Now multiply the original ratio numbers by 80 to find the numbers of boys and girls:
⇒ number of boys = 4 x 80 = 320
⇒ number of girls = 3 x 80 = 240
Total students are 560.
Let boys be 4x and girls 3x[tex]\\ \rm\hookrightarrow 4x+3x=560[/tex]

About what percent of the total area of Hal’s backyard is the area taken up by the patio, walkway, and garden? Round to the nearest whole percent
(Due by today)
Answer:
60%
Step-by-step explanation:
The total area is 136ft^2
We know this because the length of Hal's Backyard is 8+9 ft. This is a total of 17 ft in length. The width is 5+3 ft. This is a total of 8ft. Multiplying the length by the width gets us: 17ft*8ft = 136ft^2.
Now we need to find the ft^2 taken up by the padio, walkway, and garden. - We can see the image the patio is 5ft by 8ft. This is a total of 40ft^2.
- We can see the image of the garden is 3ft by 6ft. This is a total of 18ft^2
- We can see the image of the walkway is 3ft by 8ft. This is a total of 24ft^2
This adds up to a total of 82ft^2: 40ft^2+18ft^2+24ft^2 = 82ft^2
Now, to find the percentage, we divide the area of the patio, walkway, and garden by the total area:
[tex]\frac{82ft^2}{136ft^2}[/tex]
=
60%
So Hal's patio, walkway, and garden make up 60% of the total area of his backyard.

Broker U suggests that Sylvia buy two par value $1,000 bonds from Franklin County, three par value $500 bonds from Enam Telecom, and two par value $1,000 bonds from the city of Iligs. Franklin County bonds are selling at 96. 674, Enam Telecom bonds are selling at 109. 330, and Iligs bonds are selling at 103. 851. Broker V suggests that Sylvia buy four par value $500 bonds from Trochel Office Supplies, one par value $500 bond from Okaloosa county, and three par value $1,000 bonds from Globin Publishing. Bonds from Trochel Office Supplies are selling at 105. 142, Okaloosa county bonds are selling at 85. 990, and Globin Publishing bonds are selling at 97. 63. If Broker U charges a commission of 2. 8% of the market value of the bonds sold and Broker V charges a fee of $65 for each bond sold, which bond package will cost Sylvia less, and by how much? a. Broker V’s bond package will cost Sylvia $366. 00 less than Broker U’s. B. Broker V’s bond package will cost Sylvia $205. 77 less than Broker U’s. C. Broker U’s bond package will cost Sylvia $156. 02 less than Broker V’s. D. Broker U’s bond package will cost Sylvia $361. 79 less than Broker V’s.
The bond package that will cost Sylvia less will be C. broker U's package costs $156.02 less money than broker V's package.
How to calculate the bond packageBroker U: 2.8% commission
2 par value bonds $1,000 x 96.674% = $1,933.48
3 par value bond $500 x 109.330% = $1,639.95
2 par value bonds $1,000 x 103.851% = $2,077.02
Silvia's total investment:
= ($1,933.48 + $1,639.95 + $2,077.02) x 1.028
= $5,808.66
Broker V: $65 per bond plus
4 par value bonds $500 x 105.142% = $2,102.84
1 par value bond $500 x 85.990% = $429.95
3 par value bonds $1,000 x 97.063% = $2,911.89
Silvia's total investment will be:
= $2,102.84 + $429.95 + $2,911.89 + (8 x $65)

Paula invited some friends to dinner, and she plans to make fajitas. At the grocery store, she spends $2.90 on red bell peppers and $1.90 on green bell peppers. If both types of bell peppers cost $1.60 per pound, how many total pounds of bell peppers does she buy?
The pounds of pepper and the amount are illustrations of unit rates
She bought a total of 3 pounds of bell pepper
How to determine the total pounds of bell pepperThe amount spent is given as:
Red bell pepper = $2.90
Green bell pepper = $1.90
The price per pound for both type of pepper is given as:
Rate = $1.60 per pound
So, the total pound is calculated as:
Pound = Total amount / Rate
This gives
[tex]Pound = \frac{2.90 + 1.90}{1.60}[/tex]
Evaluate the sum
[tex]Pound = \frac{4.80}{1.60}[/tex]

Sam Kramer earns an annual salary of $38,900. He is paid semimonthly. His personal exemptions total $4826. The state income tax on taxable wages is 2% of the first $1000, 3% on the next $3000, 3. 5% on the nest $3000, and 4% on the amount over $7000. How much is deducted from Sam’s salary each pay period for state income tax?
Step-by-step explanation:
we pay taxes of the income without the exemptions.
so, the tax-interresting amount is
38,900 - 4826 = $34,074
2% of the first $1000 = $20
$34,074 - 1000 = $33,074
3% of the next $3000 = $90
$33,074 - 3000 = $30,074
3.5% of the next $3000 = $105
$30,074 - 3000 = $27,074
4% of $27,074 = $1,082.96
so, in total he pays state taxes over a year
20+90+105+1082.96 = $1,297.96
now, he gets paid semimonthly, that means twice a month.
his salary but also his deductions (incl. tax deductions) are all split across these 24 paychecks per year.
so, each state income tax deduction is then
$1,297.96 / 24 = $54.08 on every paycheck.
