Answer:

f^-1(x) = x - 18

Step-by-step explanation:

y = x + 18

x = y + 18

x - 18 = y

f^-1(x) = x - 18

Answer:

15.0

Step-by-step explanation:

V = pi×r^2×h

so r = 15.0

The new surface area of the figure that is 1 / 3 of the original size is 198.79 ft².

The surface area of a solid is a measure of the total area occupied by the surface of an object.

Therefore, the surface area of the figure can be calculated as follows:

surface area = (5 × 6.1) + (5 × 10) + (9.8 × 6.1) + (4.9 × 6.1) + (10 × 5) + (14.8 × 4.9) +  (10 × 5) + (14.8 × 4.9) + (14.8 × 6.1) + (14.9 × 6.1)

surface area = 30.5 + 50 + 59.78 + 29.89 + 50 + 72.52 + 50 + 72.52 + 90.28 + 90.89

original surface area = 596.38 ft²

Therefore,

New surface area = 1  / 3 × 596.38

New surface area = 198.793333333

New surface area = 198.79 ft²

Answer:

B, C, and E

Step-by-step explanation:

Since x+6 has the root x=-6, we should be getting 0 after plugging it into each expression by the Remainder Theorem:

[tex]2x^3-19x^2-7x+294\\2(-6)^3-19(-6)^2-7(-6)+294\\2(-216)-19(36)+42+294\\-432-684+42+294\\-780[/tex] <-- remainder isn't 0;  A is out

[tex]4x^3 + 11x^2 - 75x + 18\\4(-6)^3+11(-6)^2-75(-6)+18\\4(-216)+11(36)+450+18\\-864+396+468\\-864+864\\0[/tex]<-- remainder IS 0; B is a correct choice

[tex]3x^3 + 34x^2 + 61x - 210\\3(-6)^3+34(-6)^2+61(-6)-210\\3(-216)+34(36)-366-210\\-648+1224-366-210\\576-366-210\\210-210\\0[/tex]<-- remainder IS 0; C is a correct choice

[tex]x^3 + 6x^2 + 11x + 6\\(-6)^3+6(-6)^2+11(-6)+6\\-216+6(36)-66+6\\-216+216-60\\-60[/tex]<-- remainder isn't 0; D is out

[tex]10x^3 + 53x^2 - 41x + 6\\10(-6)^3+53(-6)^2-41(-6)+6\\10(-216)+53(36)+246+6\\-2160+1908+252\\-252+252\\0[/tex]<-- remainder IS 0; E is a correct choice

Thus, the correct choices are B, C, and E.

Let that be x

[tex]\\ \sf\longmapsto x=48000-0.112(48000)[/tex]

[tex]\\ \sf\longmapsto x=48000-5376[/tex]

[tex]\\ \sf\longmapsto x=42624\$[/tex]

Answer:

Decrease in price:  $5,376

Price of next model:  $42,624

Step-by-step explanation:

Decrease in Price

Find 11.2% of $48,000

First, convert 11.2% into a decimal:

⇒ 11.2% = 11.2/100 = 0.112

Multiply this by $48,000:

⇒ 0.112 × 48000 = $5376

Therefore, the decrease in price is $5,376

Price of next model

price of next model = current price - 11.2%

                                 = 48000 - 5376

                                 = $42,624

Therefore, the price of the next model is $42,624

(4x^2-3)(x^2-5)

Step-by-step explanation:

We are going to group the first two and last two terms and find the GCF of each set.

4x^4-20x^2-3x^2+15

(4x^4-20x^2)(-3x^2+15)

4x^2(x^2-5)-3(x^2-5)

Then we group the GFCs together and the rest

(4x^2-3)(x^2-5)

Answer:

40°

Step-by-step explanation:

Angle 1 and Angle 2 are corresponding angles.

Corresponding angles are congruent, so 3x + 4 = 5x - 20

Solving 3x + 4 = 5x - 20

3x = 5x - 24

2x = 24

x = 12

Substitute angle 1

3x + 4 = 36 + 4 = 40
