Answer:
No
Step-by-step explanation:
If you use the Pythagorean theorem:
sqrt (7^2+18^2)= sqrt 373 and 27^2 does not equal to 373
Answer:
No
Step-by-step explanation:
A right triangle is exactly 90 degrees and 27, 18, and 17 equal less than 90 so it does not equal a right triangle.

What is the equation, in standard form, of a circle with center (−5, −9) and radius 7?
Answer:
Equation of a circle:
(x - h)² + (y - k)² = r², where (h, k) is the center and r- radiusSubstitute the given values to get the equation of this circle:
(x - (-5))² + (y - (-9))² = 7² ⇒(x + 5)² + (y + 9)² = 49Answer:
Solution given:
Centre(h,k)=(-5,-9)
radius (r)=7
we have
Equation of a circle is;
(x-h)²+(y-k)²=r²
Substituting value;
(x+5)²+(y+9)²=7²
(x+5)²+(y-9)²=49 is a required equation of a circle.

NO LINKS AND NO JUST SAYING HI, PLEASE ANSWER LEGITIMATELY! THANK YOU!!!! <3
Answer:
x=42.5
Step-by-step explanation:
First, start by setting up the equation
these are both same side interior angles, so they both add up to 180
(3x+10) + x = 180
4x+10 =180
subtract both sides by 10
-10 -10
4x=170
divide both sides by 4
x=42.5

Find the measure of the indicated angle. Need help please.
I need explanation
Answer:
BC =21.03540021
Step-by-step explanation:
We know the measure of angle B since the sum of the angles of a triangle add to 180
A + B+ C = 180
61+ B + 12 =180
B = 180 - 12 -61
B =107
Then we can use the law of sines to find BC
sin B sin A
-------- = -------------
AC BC
sin 107 sin 61
-------- = -------------
23 BC
Using cross products
BC sin 107 = 23 sin 61
BC = 23 sin 61/ sin 107
BC =21.03540021
Answer:
20.12m
Step-by-step explanation:
180 - (12 + 61) = 107° = ∡B
[tex]\frac{23}{sin(107)} = \frac{a}{sin(61)}[/tex] *Cross Multiply*
[tex]a(sin(107)) = 23(sin(61))[/tex] *Divide by sin(107)*
[tex]a = \frac{23(sin(61))}{sin(107)}[/tex] *Solve*
a = BC ≈ 20.12m
A fourth degree polynomial has real roots at 0, 3, a double real root at -1, and passes through the point
(2, 12). Write the particular equation of the function
Answer:
Step-by-step explanation:
y = a * x(x - 3)(x + 1)^2
2,12 is used to find the value of a
y = a (2)(2 - 3)(2 + 1)^2
12 = a (2)(-1)(3)^2
12 = a (2) (-1) (9)
12 = - 18*a
12/-18 = a
a = - 2/3
y = (-2/3)*x*(x - 3)(x + 1)^2

A Sale at Tinley’s Department Store Tinley’s department store is having a 25% off sale. Victor has a $15 Tinley’s gift certificate that he wants to use towards a sweater with an original price of $32.00. He is unsure which method the sales clerk will use to calculate the amount owed. Method #1: Subtract $15 from the price and take 25% off the resulting price. Method #2: Take 25% off the original price and then subtract $15.
Answer:
Method 1: $12.75
Method 2: $9
Step-by-step explanation:
method #1: 32-15 is $17
In order to take off a percentage, we must find that percentage of the amount. To do this, we must multiply by the percent in decimal form, so
[tex]17 \times .25 = 4.25[/tex]
Now, this amount just represents the percent of 17 we would take off, so we must take that amount off.
[tex]17 - 4.25 = 12.75[/tex]
We would pay $12.75
Method #2:
There are a few ways to do this with 25%. we know 25% is 1/4, and 1/4 or $32 is 8. so we can simply take that off from the start. Otherwise, we can follow the method above as follows
[tex]32 \times .25 = 8[/tex]
Again, this is the amount off so we must subtract.
[tex]32 - 8 = 24[/tex]
now, we subtract 15.
[tex]24 - 15 = 9[/tex]
We would pay $9 using this method.
Hope this helps!

If the 13th term in a linear sequence is 92 and the 28th term in the sequence is
152, what is the 6th term in the sequence?
Answer:
64
Step-by-step explanation:
As the sequence is linear the rate of increase stays constant as we can see from the formula: [tex]S_n=mn+i[/tex] so it increases by m every term. In this all we do is subtract 13 from 28 to find the number of terms in between:
28-13=15
now we find the difference between 152 and 92
152-92=60
now we divide 60 and 15
60÷15=4
So M is 4 meaning every term has a difference of 4.
So now we can subtract 6 from 13:
13-6=7
Then multiply the difference per term (4) by 7
4×7=28
Finally we subtract 28 from 92 (13th terms value)
92-28=64

Marjorie needs to calculate how much water a cylindrical tank will hold. The tank is 9 feet high and has a diameter of 5 feet. Her work is shown below.
V = pi r squared h
Step 1: V = pi (2.5 squared) (9)
Step 2: V = pi (5) (9)
Step 3: V = (3.14) (5) (9)
Step 4: V = 141.3 cubic feet
What error did Marjorie make when calculating the volume of the tank?
In step 1, she substituted into the volume formula incorrectly.
In step 2, she calculated 2.5 squared incorrectly.
In step 3, the she substituted the wrong amount for Pi.
Marjorie correctly calculated the volume of the cylinder.
Answer:
in step 2, she calculated 2.5^2 incorrectly.

In circle K shown below, points B, C, D, and E lie on the circle with secants HBD and HCE drawn. Prove:
HExDC=HDxEB
Answer:
By exterior angle theorem, we have;
∠DBE = ∠H + ∠HEB = ∠ECD = ∠H + ∠HDC
∴ ∠H + ∠HEB = ∠H + ∠HDC
By addition property of equality, we have
∠HEB = ∠HDC
∠H = ∠H by reflexive property
∴ ΔHCD ~ ΔHEB by Angle Angle AA similarity postulate
∴ HE/HD = EB/DC, by the definition of similarity
Therefore, by cross multiplication, we have;
HE × DC = EB × HD
Therefore, by commutative property of multiplication, we have;
HE × DC = HD × EB

Answer:
x = 5
Step-by-step explanation:
The x-coordinate of the solution can be found by subtracting the second equation from 7 times the first.
7(5x +7) -(-10x +7y) = 7(27) -(-36)
45x = 225 . . . . . simplify
x = 5 . . . . . . . . . . divide by 45
The x-coordinate of the solution is 5.
