Answer:

c. w = 2/3l

Step-by-step explanation:

for a., none of the values fit so it can't be a.

for b., the second row fits but none of the others do so it can't be b.

for c., every single row fulfills the equation so the answer is c.

for d., the first row fits but none of the others do so it can't be d.

<em>since there are only four choices it's fine to plug and test. </em>

Each pair of polygons is similar. Find the value of x.
Rus_ich [418]

Answer:

The value of x is 1.5

Step-by-step explanation:

<em>In similar figures, corresponding sides have the same ratio</em>

In the given figure

∵ There are 2 similar polygons

∴ We must write their names with corresponding angles

∵ ∠A = ∠L, ∠B = ∠M, ∠C = ∠N, ∠D = ∠P

∴ Their names are ABCD and LMNP

→ By using the rule above

∴ Their corresponding sides have the same ratio

∴ \frac{AB}{LM} = \frac{BC}{MN}

∵ AB = 14 and LM = x + 9

∵ BC = 10 and MN = x + 6

→ Substitute them in the ratio up

∴ \frac{14}{x+9} = \frac{10}{x+6}

→ By using the cross multiplication

∵ 14 × (x + 6) = 10 × (x + 9)

∴ 14(x) + 14(6) = 10(x) + 10(9)

∴ 14x + 84 = 10x + 90

→ Subtract 10x from both sides

∵ 14x - 10x + 84 = 10x - 10x + 90

∴ 4x + 84 = 90

→ Subtract both sides by 84

∵ 4x + 84 - 84 = 90 - 84

∴ 4x = 6

→ Divide both sides by 4 to find x

∴ x = 1.5

∴ The value of x is 1.5

Determine and state the maximum error of the function G(x,y,z)=20 ln⁡(xyz^2 ) using differentials when (x,y,z)=(2,3,4) and given
Leona [35]

Answer:

The maximum error in the function G, ΔG = ±4

Step-by-step explanation:

G(x,y,z) = 20 In (xyz²)

Total or maximum error for a multi-variable function is given by

ΔG = (∂G/∂x) (Δx) + (∂G/∂y) (Δy) + (∂G/∂z) (Δz)

(∂G/∂x) = 20yz²/xyz² = 20/x

(∂G/∂y) = 20xz²/xyz² = 20/y

(∂G/∂z) = 40xyz/xyz² = 40/z

Δx = ±0.10

Δy = ±0.15

Δz = ±0.20

ΔG = (∂G/∂x) (Δx) + (∂G/∂y) (Δy) + (∂G/∂z) (Δz)

ΔG = (20/x) (0.10) + (20/y) (0.15) + (40/z) (0.2)

At the point (x,y,z) = (2,3,4)

ΔG = (20/2) (0.10) + (20/3) (0.15) + (40/4) (0.2) = 10(0.10) + 20(0.05) + 10(0.2) = 1 + 1 + 2 = 4

ΔG = ±4
