G = 10

⓵ You need to replace g with its value and calculate everything :

9 - 4(10) + 1 = ×

9 - (4•10) + 1 = ×

9 - 40 + 1 = ×

-31 + 1 = ×

-30 = ×

So your answer is -30!

I really hope this helped, if there’s anything just let me know! ☻

-30, 10*4=40 so you do 9-40+1 which is equal to -30

Answer:

125in³

Step-by-step explanation:

A box that would perfectly fit the bowling ball will be a cube shape.

The box will have the dimensions 5in by 5in by 5in. These dimensions come from the diameter for the ball.

Calculate volume using V = s³, where "s" stands for a side.

V = s³

V = (5in)³

V = 125in³

Mr. Ryan needs a box with the volume 125 cubic inches.

Expanding logarithmic Expression In Exercise,Use the properties of logarithms to rewrite the expression as a sum,difference,or m

wel

Answer:

$\frac{1}{2}ln(2x)-\frac{1}{2}ln(x^2-1)$

Step-by-step explanation:

In 2x/(x^2 - 1)1/2

$ln(\frac{2x}{x^2-1} )^\frac{1}{2}$

Apply the property of natural log

ln x^m = m ln(x) move the exponent before ln

$ln(\frac{2x}{x^2-1} )^\frac{1}{2}$

$\frac{1}{2}ln(\frac{2x}{x^2-1})$

ln(m/n)= ln m - ln n

$\frac{1}{2}(ln(2x)-ln(x^2-1))$

multiply 1/2 inside the terms

$\frac{1}{2}ln(2x)-\frac{1}{2}ln(x^2-1)$

Help I need it now!!<br> T14= 46, and t20= 100, find t3, t7, and tn

Vinil7 [7]

Answer:

$t_3 = -53\\\\\\t_7 = -17\\t_n= -80 +9n$

Step-by-step explanation:

Arithmetic sequence:

$\sf \boxed{t_n=a+(n-1)d}$

Here a is the first term and d is the common difference.

$t_{14}= 6$ ⇒ $\sf a + 13 d = 46$ ------------(I)

$\sf t_{20} = 100$ ⇒ a + 19d = 100 ---------(II)

Subtract equation (I) from (II)

(I1) a + 19d = 100

(II) a + 13d = 46

<u>- - -</u>

6d = 54

d = 54 ÷ 6

$\sf \boxed{d = 9}$

Substitute d = 9 in equation(I) and find 'a',

a + 13*9= 46

a + 117 = 46

a = 46 - 117

a = -71

$\sf t_3 = -71 + 2*9$

= -71 + 18

= -53

$\sf t_7 = -71 + 6*9$

= -71 + 54

= -17

$\sf t_n= -71 + (n-1)*9$

= -71 + 9*n - 1 *9

= -71 + 9n - 9

= -71 - 9 + 9n

= - 80 + 9n

A cafeteria measures 40 feet by 60 feet.

Mariulka [41]

B, feet squared.
This is because we are finding the area of a square, not a cube.
