Answer:
The center of the circle is point: C=(1,5).
The radius of the circle is r=3.
Step-by-step explanation:
x² + y² -2x - 10y + 17 = 0
Find the center and radius of this circle
We have the equation
x² + y² -2x - 10y + 17 = 0
We collect like terms
x² - 2x + y² - 10y = -17
x² - 2x + (-2/2)² + y² - 10y + (-10/2)² = -17 + (-2/2)² + (-10/2)²
The center of the circle is point: C=(1,5).
The radius of the circle is r=3.

Answer:
150 boys
Step-by-step explanation:
equation:
⇒ 5x + 4x = 270
add like terms:
⇒ 9x = 270
divide 9 on both sides:
⇒ [tex]\frac{9x}{9} = \frac{270}{9}[/tex]
solve:
⇒ x = 30
take original equation and subtitute 30 for x;
⇒5 x 30 + 4 x 30 = 270
⇒ 150 + 120 = 270
We can see that if there were 270 students, 150 would be boys and 120 would be girls.
Can someone plz help me I beg u :(
Choose the statement that is not true.
Answer:
1 and 3
Step-by-step explanation:
Use mathematical induction to prove the statement is true for all positive integers n. 1^2 + 3^2 + 5^2 + ... + (2n-1)^2 = (n(2n-1)(2n+1))/3)
Answer:
The statement is true is for any [tex]n\in \mathbb{N}[/tex].
Step-by-step explanation:
First, we check the identity for [tex]n = 1[/tex]:
[tex](2\cdot 1 - 1)^{2} = \frac{2\cdot (2\cdot 1 - 1)\cdot (2\cdot 1 + 1)}{3}[/tex]
[tex]1 = \frac{1\cdot 1\cdot 3}{3}[/tex]
[tex]1 = 1[/tex]
The statement is true for [tex]n = 1[/tex].
Then, we have to check that identity is true for [tex]n = k+1[/tex], under the assumption that [tex]n = k[/tex] is true:
[tex](1^{2}+2^{2}+3^{2}+...+k^{2}) + [2\cdot (k+1)-1]^{2} = \frac{(k+1)\cdot [2\cdot (k+1)-1]\cdot [2\cdot (k+1)+1]}{3}[/tex]
[tex]\frac{k\cdot (2\cdot k -1)\cdot (2\cdot k +1)}{3} +[2\cdot (k+1)-1]^{2} = \frac{(k+1)\cdot [2\cdot (k+1)-1]\cdot [2\cdot (k+1)+1]}{3}[/tex]
[tex]\frac{k\cdot (2\cdot k -1)\cdot (2\cdot k +1)+3\cdot [2\cdot (k+1)-1]^{2}}{3} = \frac{(k+1)\cdot [2\cdot (k+1)-1]\cdot [2\cdot (k+1)+1]}{3}[/tex]
[tex]k\cdot (2\cdot k -1)\cdot (2\cdot k +1)+3\cdot (2\cdot k +1)^{2} = (k+1)\cdot (2\cdot k +1)\cdot (2\cdot k +3)[/tex]
[tex](2\cdot k +1)\cdot [k\cdot (2\cdot k -1)+3\cdot (2\cdot k +1)] = (k+1) \cdot (2\cdot k +1)\cdot (2\cdot k +3)[/tex]
[tex]k\cdot (2\cdot k - 1)+3\cdot (2\cdot k +1) = (k + 1)\cdot (2\cdot k +3)[/tex]
[tex]2\cdot k^{2}+5\cdot k +3 = (k+1)\cdot (2\cdot k + 3)[/tex]
[tex](k+1)\cdot (2\cdot k + 3) = (k+1)\cdot (2\cdot k + 3)[/tex]
Therefore, the statement is true for any [tex]n\in \mathbb{N}[/tex].

Sophia and her friends are eating lunch in the city. The
bill is $45.00 before tax. The girls want to leave a 15%
tip on the total bill with tax. How much will the total bill
be including tax and tip if tax is 8%?
Answer:
I believe it would be $52.29
Step-by-step explanation:
You put $45.00 with 15% in a percentage calcuator, (math w ay might work,) which gives you 6.75 and you put the tax of 8% in a tax calculator which gives you 7.29.
Then you just add $45.00 + 7.29 = $52.29!

Answer:
Step-by-step explanation:
First you need to calculate the entire length (in meters) of the metal used in the gate, then multiple the length by 2.5 kg per meter
Break it into parts.......
four pieces on along the outside is just the perimeter of a rectangle
P = 2( L + H) both sides and the top and bottom
the two crossing metal pieces are just the hypotenuse of a right triangle and since we have two pieces of metal
a² + b² = c² or L² + H² = Hyp² solving for the htpotenuse
Hyp = [tex]\sqrt[]{L^2 + H^2}[/tex]
so the total length of the gate metal is
P = 2( L + H) plus 2 Hyp = [tex]\sqrt[]{L^2 + H^2}[/tex]
= 2( 12 + 5) + 2 [ √(12² + 5²) ]
= 34 + 2 [ √( 144 + 25) ]
= 34 + 2 ( √169)
= 34 + 2( 13)
= 34 + 26
= 60 meters of gate metal metal weighs 2.5 kg per meter
Total weight equals 60 meters times 2.5 kg per meter
Total weight = 60 (2.5) = 150 kg

Q3. In a hydraulic lift, a 1400 N force is applied to a 0.5 m2 piston. Calculate the minimum surface area of the large piston to lift 5000 N.
Answer:
1.8m^2 approx
Step-by-step explanation:
Given data
P1= 1400N
A1=0.5m^2
P2=5000 N
A2=??
Let us apply the formula to calculate the Area A2
P1/A1= P2/A2
substitute
1400/0.5= 5000/A2
cross multiply
1400*A2= 5000*0.5
1400*A2= 2500
A2= 2500/1400
A2= 1.78
Hence the Area is 1.8m^2 approx

Suppose that cand d vary inversely and that d = 2/9 (2 over 9) when c = 5.
Write a function that models the inverse variation and find d when c = 8.
Answer:
d = 10/72
Step-by-step explanation:
c and d vary inversely
c = k/d
Where,
k = constant of proportionality
d = 2/9 when c = 5
c = k/d
5 = k ÷ 2/9
5 = k × 9/2
5 = 9k/2
Cross product
5*2 = 9k
10 = 9k
k = 10/9
c = k/d
c = 10/9 ÷ d
c = 10/9 × 1/d
c = 10/9d
find d when c = 8
c = 10/9d
8 = 10/9d
Cross product
8*9d = 10
72d = 10
d = 10/72
A skyrocket is launched from a 30–foot-high platform, with initial speed 300 ft/s. If the polynomial −16t2 + 300t + 30 gives the height that the rocket will rise in t seconds, how high will a rocket with a 2–second fuse rise? The rocket will rise feet.
Answer:
566 ft
Step-by-step explanation:
Given the polynomial equation
-16t² + 300t + 30 = 0
We're asked to find how high the rocket would rise in a 2 second fuse rise. This is a simple instruction that can be obtained by setting the unknown, t, in the equation to 2. Doing this, we have
-16 * 2² + 300 * 2 + 30
-16 * 4 + 600 + 30
-64 + 630 = 566 ft
Then, we can therefore conclude that the rocket will rise high up to a distance of 566 ft

v/22 - 0.1 = 7.4 what is v?
Answer:
v = 165
Step-by-step explanation:
v/22 -0.1 = 7.4
v/22 = 7.4+0.1 =7.5
v = 7.5*22
v = 165
Answer:
[tex]v = 165[/tex]
Step by step Explanations:1) Add 0.1 to both sides.
[tex] \frac{v}{22} = 7.4 + 0.1[/tex]
2) Simplify 7.4 + 0.1 to 7.5.
[tex] \frac{v}{22} = 7.5[/tex]
3) Multiply both sides by 22.
[tex]v = 7.5 \times 22[/tex]
4) Simplify 7.4 × 22 to 165.
[tex]v = 165[/tex]
Therefor, the answer is v = 165.

Answer:
32 / (10 - 8) / 2 - 31/2 * (12 / 2 - 2) + 11Note: The mention of parantheses makes me believe they are asking for one-line expressions with no fractions. If this is incorrect, replace the slashes with fraction lines with the addition and subtraction outside of said fractions.
The equivalent expression, which includes a set of parentheses that make the value of the expression 5 and 13 are,
[tex]10-\dfrac{32}{8}+(2-3)=5[/tex]
[tex]\dfrac{1}{2}\times[(12\div 2)-2]+11=13[/tex]
What is the equivalent expression?Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
Create an equivalent expression that includes a set of parentheses that make the value of the expression 5.
32 divided by 10 - 8 divided by 2 - 3. Make the expression with assuming the result as n.
[tex]n=10-\dfrac{32}{8}+(2-3)\\n=10-4-1\\n=5[/tex]
Create an equivalent expression that includes a set of parentheses that make the value of the expression 13.
1/2 x 12 divided by 2 - 2 + 11
Make the expression with assuming the result as n.
[tex]n=\dfrac{1}{2}\times[(12\div 2)-2]+11\\n=\dfrac{1}{2}\times[6-2]+11\\\\n=\dfrac{1}{2}\times4+11\\n=2+11\\n=13\\[/tex]
Thus, the equivalent expression which includes a set of parentheses that make the value of the expression 5 and 13 are,
[tex]10-\dfrac{32}{8}+(2-3)=5[/tex]
[tex]\dfrac{1}{2}\times[(12\div 2)-2]+11=13[/tex]
