Name the marked angle ( < KLI ) in 2 different ways[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
You can name the angle as < ILK too.Why? Well, to name an angle you only need to focus on keeping the vertex of the angle (the middle point where the angle gets formed) in the middle while naming. In this case the vertex is L. Then you can just shift the places of the 2 arms of the angle ( I & K ) & yea, then you'll get the name of the angle as < ILK.What are are the domain and range of f(x) = (1/6)^×+2?

Toy rubber balls are packaged in a cylinder that holds 3 balls. The diameter of each ball is 4.5 cm. Find the volume of the cylinder. Use 3.14 for π. (Round to the nearest tenth as needed.)
Answer:
214.6 cm³Step-by-step explanation:
Volume formula:
V = πr²hGiven:
d = 4.5 cmh = 3*4.5 cmFind the volume:
V = 3.14*(4.5/2)²*(3*4.5) = 214.6 cm³ (rounded)
Answer :-
Total height = 4.5 × 4.5 × 4.5 = 91.125 cm
Radius = Diameter/2
Radius = 4.5/2 = 2.25 cm
Volume = πr²h
Volume = π (2.25)² × 91.125
Volume = π × 12.25 × 91.125
Volume = 1116.2 π cm³

If DE = 4 x + 10, EF = 2 x -1, and DF = 9 x - 15, what is the length of DF?
Answer:
DF = 57
Step-by-step explanation:
DE + EF = DF
(4x + 10) + (2x - 1) = 9x - 15
Combine like terms on the left side
6x + 9 = 9x - 15
Subtract 6x on both sides
9 = 3x - 15
Add 15 on both sides
24 = 3x
Divide by 3 on both sides
x = 8
DF = 9x - 15 = 9(8) - 15 = 72 - 15 = 57
Checking:
(4(8) + 10) + (2(8) - 1) = 9(8) - 15
(32 + 10) + (16 - 1) = 72 - 15
58 - 1 = 72 - 15
57 = 57
Answer:
DF= DE+EF
9x–15 = (4x+10)+(2x-1)
9x–15 = 6x +9
9x–6x= 9+15
3x = 24
x=24/3
x=8
DF = 9x –15 = 9(8)–15= 72 –15 = 57
So; DF = 57

What value of b makes the expression x^2 + bx + 4 a perfect square?
1
0
2
4
Answer:
b=4 makes the equation a perfect square.
Step-by-step explanation:
As long as you factorize out the equation, you'll get a result of (x+2)^2. This multiplied using foil gives you, x^2 + 2x + 4. Making it a perfect square. You could also have -2 = b which makes a perfect square, but that's not in the options.
Answer:
4
Step-by-step explanation:
The constant term 4 is obtained by
adding (half the coefficient of the x- term)²
4 = 2²
Then b = 4
x² + 4x + 4 = (x + 2)² ← a perfect square

A scientist has 3^15 cells in a container. She expects the number of cells to triple in on day. How many cells will the scientist have after one day? Show your work or explain your reasoning
Answer:
3^16 cells
Step-by-step explanation:
The scientist has 3^15 cells. If we triple the number of cells, we multiply this amount by 3
3 * 3^15 = 3^1 * 3^15
Remember your laws of exponents: we add the exponents here.
3^(1+15) = 3^16
Diagram 6 shows a rectangle KLMN.
It is given that tan x = 0.8. Find the length, in cm, of LM.
A 16
B 20
C 24
D 26
HELP ME PLS
Answer:
LM = 24 cm
Step-by-step explanation:
Using the tangent ratio in the right triangle to find JL
tan x = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{JL}{KL}[/tex] = [tex]\frac{JL}{10}[/tex] = 0.8 ( multiply both sides by 10 )
JL = 8
Then
LM = JL + JM = 8 + 16 = 24 cm
soultion for 3x-5=2x+3-(x-4)
Answer:
6
Step-by-step explanation:
Initial problem:
3x - 5 = 2x + 3 - (x - 4)
First, distribute the minus sign to the parentheses:
3x - 5 = 2x + 3 - x + 4
Next, combine like terms:
3x - 5 = x + 7
Subtract x from both sides:
2x - 5 = 7
Add 5 to both sides:
2x = 12
Divide both sides by 2:
x = 6
helpppp with geometry plzzz
Step-by-step explanation:
a) given slope=m1=4/b
parallel slope=m2=-8
when two lines are parallel their reltion of slopes is:
m1=m2
4/b=-8
b=-4/8
b=-1/2
b) m1=4/b , m2=3/4
when slopes are perpendicular their relation of slopes is:
m1×m2=-1
