Let f(x) = 3x² + 2x – 4 and g(x) = 5x + 7.
Which of the following terms will be part of f(x) + g(x)?

Answer:

D) 13

Step-by-step explanation:

a² + b² = c²

5² + 12² = c²

25 + 144 = c²

169 = c²

[tex]\sqrt{c^2} =\sqrt{169}[/tex]

c = 13

Hope that helps :)

Answer:

our inputs are 3 & 1/2

Step-by-step explanation:

the ? is the slope and the slope is equal to 1/2 so

?=1/2

the point slope formula is

(y-y1)=m(x-x1)  (x1,y1)--> a point on the line  m--> slope

so we chose (x1,y1) as (3,0)

when we plug that in we get

y-0=1/2(x-3)

so our inputs are 3 & 1/2

Answer:

y= 3x+10

The slope represents a rate of 3 cm per week

The y-intercept represents an initial height of 10 cm

it takes 24 weeks for the height to reach 82 cm

Answer:

A() it is located _25 and is the right of point A on the number line

Answer:

The Answer is C

Step-by-step explanation:

so if u draw out a number line, point A will be on the left side of the number line or in this case "0". So it is saying "point b is 5 less than point A" so since Point A is "-20" and it says "5 less than point A" so it would be adding up 5 more to -20 so it would be -25. But if it was 5 more than point A it would have been -15. If u take an example of money, like if u owe someone $20, it would be -$20 in your balance, and if he or she says u need to owe me 5 more $'s cuz there was damage now in your balance it would be -25.

Step-by-step explanation:

Answer:

B (39)

Step-by-step explanation:

Using the Pythagorean theorem (a^2+b^2=c^2) and X=BC length

15^2+36^2=x

225+1296=x

√1521=x

x=39

Answer:

B.

Step-by-step explanation:

The Pythagorean Theorem

a^2+b^2=c^2

In this case it's c^2=a^2+b^2

c^2=15^2+36^2

c^2=225+1296

c^2=1521

c= the square root of 1521

c=39

So...

the length of line segment BC is 39

Answer:

Step-by-step explanation:

QA = QC = 5.9    ⇒    PA = 27.4 - 5.9 = 21.5

PB = PA = 21.5

CR = BR = 12.2

So, the perimeter:

P = 27.4 + 5.9 + 2×12.2 + 21.5 = 79.2

The perimeter of the triangle PQR is 79.2 units.

Perimeter of a straight sided figures or objects is the total length of it's boundary.

Given a triangle PQR.

An incircle is drawn inside the triangle.

We know that the length of the tangents which are drawn from an exterior point to the circle are equal.

Using this property and the given lengths,

PQ = 27.4

PR = (27.4 - 5.9) + 12.2 = 33.7

QR = 5.9 + 12.2 = 18.1

Perimeter of the triangle = 27.4 + 33.7 + 18.1 = 79.2 units

Hence the perimeter is 79.2 units.

Q. 3

[tex]V_{cone} =565.2\: cm^3 [/tex]

Q. 4

[tex] V_{cone} =3,014.4\: cm^3 [/tex]

Step-by-step explanation:

Q. 3

Radius of the cone (r) = 6 cm

Height of the cone (h) = 15 cm

[tex]\because V_{cone} =\frac{1}{3} \pi r^2 h[/tex]

[tex]\therefore V_{cone} =\frac{1}{3}\times 3.14 (6)^2 (15)[/tex]
