Answer:

-9

Step-by-step explanation:

Using the sum/difference property of logarithms, we can rewrite the expression given as:

log b^3 + log c^3 - log √(a^3) --> log √(a^3) can also be written as log a^1.5

Next, we can use the power property of logarithms, and rewrite it again as:

3log b + 3log c - 1.5log a

Now, we can substitute the values of log a, log b, and log c:

3(11) + 3(-9) - 1.5(10)

33 - 27 - 15

-9

Simplifying, we get -9 as the answer.

Answer:

Which object has a taller height based on the given information?

Object A: a parallelogram with an area of 60m2 and a base of 10m

Object B: a parallelogram with an area of 40m2 and a base of 4m

Object A

OR

Object B: (Correct)

Step-by-step explanation:

Because the base of B is 4m but the hight is 10m2 because 10x4=40

Answer:

[tex] \sin( \theta) = \frac{24}{25} \\ \theta = { \sin }^{ - 1} ( \frac{24}{25} ) \\ \theta = 73.7 \degree \\ \\ \tan( \theta) = \tan(73.7 \degree) \\ = 3.4[/tex]

Answer:

614

Step-by-step explanation:

15 x 13 = 195    two times   195 x 2 = 390

4 x 15 = 60    two times   60 x 2 = 120

4 x 13 = 52      two times   52 x 2 = 104

104 + 120 + 390 = 614

Answer:

SA = 2(l·w)+2(w·h)+2(l·h)

SA = 614 sq in

Step-by-step explanation:

SA = 2(4x13)+2(13x15)+2(4x15)

= 2(52)+2(195)+2(60)

= 104 + 390 + 120

= 614

Answer:

x = -16 or x = 6

Step-by-step explanation:

To find the roots of a polynomial function, set the polynomial equal to zero and solve for x.

x² + 10x - 96 = 0

We need to factor the left side. The left side is a quadratic polynomial whose first coefficient is 1. We need two numbers whose product is -96 and whose sum is 10. The numbers are 16 and -6.

(x + 16)(x - 6) = 0

If a product of two factors equals zero, then one factor or the other or both must equal zero.

x + 16 = 0  or  x - 6 = 0

x = -16 or x = 6

--------

So lets multiply first,

163 × 80 = 13,040

153 × 47 = 7,191

153 × 33 = 5,049

-------

Next, we subtract:

13,040 - 7,191 - 5,049 = 820

The value of the given expression is 7x.

A mathematical statement containing variables and numbers connected by at least one arithmetic operation is called an expression.

Given is an expression, [tex]e^{ln7x[/tex]

Let

[tex]y = e^{ln7x[/tex]

Taking ln both the sides,

[tex]ln(y) = ln(e^{ln7x})[/tex]

㏑ y = ㏑ 7x ㏑ e

㏑ y = ㏑ 7x

y = 7x

Hence, the value of the given expression is 7x.

Which is the length of HJ expressed in terms of π?

PLZ help

The formula to calculate arc length when central angle is in degrees =

Arc length = θ/360 × 2πr

r = radius = 1

θ = 81°

Hence:

Arc length in π =

= 81/360 × 2 × π × 1

= 162π/360

= 9π/20

Therefore, the arc length = 9π/20

Answer:

Area of remaining plastic = 36.55 cm² (Approx.)

Step-by-step explanation:

Given:

Diameter of plastic dial of telephone = 8 cm

Diameter of middle hole = 4 cm

Diameter of ten small holes = 1.2 cm

Find:

Area of remaining plastic

Computation;

Radius of plastic dial of telephone = 8/2 = 4 cm

Radius of middle hole = 4/2 = 2 cm

Radius of ten small holes = 1.2/2 = 0.6 cm

Area of remaining plastic = Area of plastic dial - Area of middle hole - 10[Area of small holes]

Area of remaining plastic = π(4)² - π(2)² - π(0.6)²

Area of remaining plastic = π(16) - π(4) - π(0.36)

Area of remaining plastic = π[16 - 4 - 0.36]

Area of remaining plastic = π[11.64]

Area of remaining plastic = (3.14)(11.64)

Area of remaining plastic = 36.5496

Area of remaining plastic = 36.55 cm² (Approx.)

Step-by-step explanation:

Using the sine ratio or the cosine ratio in the right triangle.

Choosing the sine ratio with the exact value

sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )

Answer:

x = 7; y = 8; z = 5

Step-by-step explanation:

x = 15 - y

y = 13 - z

z = 12 - x

The first equation is solved for x. Substitute x in the third equation with 15 - y from the first equation.

z = 12 - (15 - y)

z = 12 - 15 + y

z = y - 3       (Equation 1)

Now substitute y - 3 for z in the original second equation.

y = 13 - z

y = 13 - (y - 3)

y = 13 - y + 3

2y = 16

y = 8

Substitute 8 for y in Equation 1.

z = y - 3

z = 8 - 3

z = 5

Substitute 5 for z in the original third equation.

5 = 12 - x

-7 = -x

x = 7

Solution: x = 7; y = 8; z = 5

Answer: C: the Delian problem

Answer:141.3

Step-by-step explanation:

The volume would be the Cone + Cylinder. So, use 1/3 x pi x r^2 x h and since the height is 6-3=3, you get 9 x 3.14 x 6 x 1/3 which is 56.52. The volume of the cylinder is pi x r^2 x h, which is 9 x 3.14 x 3, is 84.78. Now, add 56.52+84.78 = 141.3. Hope this helps
