Write the slope of the line containing each pair of points.
1. (3, 4) and (5, 7)
2. (5, 2) and (9,4)
Kinda confused on this
Answer:
1) 1.5 2) 0.5
Step-by-step explanation:
To find slope using two points like (x1,y1) and (x2,y2), the slope is (y2-y1)/(x2-x1), so for first question (7-4)/(5-3) = 3/2 = 1.5, and same for the second question.

The radius of the semicircle in the following composite figure is 8.5 millimeters. What is the total area of the composite figure rounded to the nearest hundredth?
257.43 mm2
185.43 mm2
370.87 mm2
298.87 mm2
Answer:
area of semicircle only = 113.43 mm²
total area = 185.43 mm²
Step-by-step explanation:
(8.5²)(π)(0.5) = 113.43 mm²
(12)(12)(.5) = 72 mm²
72 + 113.43 = 185.43 mm²

what is % of $2 = $1
Answer:
50%
Step-by-step explanation:
Let [tex]x[/tex] be equal to the decimal when multiplied by 2 equals 1
[tex]2x=1[/tex]
Divide both sides by 2
[tex]\frac{2x}{2} =\frac{1}{2} \\x=0.5[/tex]
Multiply the decimal by 100 to get a percent
0.5×100=50%

19, 13.5,8,2.5
Answer:
Go by three??
Step-by-step explanation:
I honestly do not know
Answer:
-3 , -8.5
Step-by-step explanation:
subtract 5.5
19, ........19-5.5 = 13.5
13.5 -5.5 = 8
8 -5.5 = 2.5
2.5-5.5 = -3
-3-5.5 = -8.5

The first term of a geometric sequence is 18 and the multiplier is 3.5. What is the 5th term of the sequence?
Answer:
2701.125
Step-by-step explanation:
fifth term = 18(3.5)^4
Answer:
a₅ = 2701.125
Step-by-step explanation:
Multiply each term by 3.5 , that is
a₁ = 18
a₂ = 3.5 × 18 = 63
a₃ = 3.5 × 63 = 220.5
a₄ = 3.5 × 220.5 = 771.75
a₅ = 3.5 × 771.75 = 2701.125

If using the method of completing the square to solve the quadratic equation
x2 + 13x -3 = 0, which number would have to be added to "complete the
square"?
Answer:
Step-by-step explanation:
The term added which completes the square is half of the linear coefficient squared. In a quadratic ax^2+bx+c, b is the linear coefficient, so in this case the added term would be
(13/2)^2=169/4=42.25
The term 13/2 is added to complete the square.
What is a quadratic equation?
A quadratic equation is a polynomial which has the highest degree equal to two. It is a second-degree equation of the form ax² + bx + c = 0, where a, b, are the coefficients, c is the constant term, and x is the variable.
For the given situation,
The quadratic equation is x^2 + 13x -3 = 0.
This is not the perfect square term. So we can solve this by using the completing the square method.
⇒ [tex]x^{2} +13x-3=0[/tex]
⇒ [tex]x^{2} +13x=3[/tex]
⇒ [tex]x^{2} +13x + (\frac{13}{2})^{2} =3+(\frac{13}{2})^{2}[/tex]
⇒ [tex](x+\frac{13}{2} )^{2} =3+\frac{169}{4}[/tex]
⇒ [tex](x+\frac{13}{2} )^{2} =\frac{181}{4}[/tex]
⇒ [tex]\sqrt{ (x+\frac{13}{2} )}^{2} =\sqrt{\frac{181}{4}}[/tex]
⇒ [tex](x+\frac{13}{2})[/tex] = ± [tex]\frac{\sqrt{181} }{2}[/tex]
Hence we can conclude that the term 13/2 is added to complete the square.
