Answer:

y=10(3.16)^x

Step-by-step explanation:

Given equation is,

log(y) = 0.5x + 1

We can rewrite this equation as,

\text{log}_{10}(y)=0.5x+1

y = 10^{(0.5x+1)}

[If \text{log}_a(b)=c, then b = a^{c}]

y = 10(10)^{0.5x}

y = 10[(10)^{0.5}]^x

y = 10(3.16)^x [Since, 10^{0.5}=3.16]

Therefore, y=10(3.16)^x will be the answer.

Illusion [34]
Would need the net to answer. but to find the answer you need to find the slant height of the square pyramid, the slant height is the hypotenuse of the right triangle formed by the height and half the base length. Use the pythagorean Theorem

Answer:

10m x 15m

Step-by-step explanation:

You are given some information.

1. The area of the garden: A₁ = 150m²

2. The area of the path: A₂ = 186m²

3. The width of the path: 3m

If the garden has width w and length l, the area of the garden is:

(1) A₁ = l * w

The area of the path is given by:

(2) A₂ = 3l + 3l + 3w + 3w + 4*3*3 = 6l + 6w + 36

Multiplying (2) with l gives:

(3) A₂l = 6l² + 6lw + 36l

Replacing l*w in (3) with A₁ from (1):

(4) A₂l = 6l² + 6A₁ + 36l

Combining:

(5) 6l² + (36 - A₂)l +6A₁ = 0

Simplifying:

(6) l² - 25l + 150 = 0

This equation can be factored:

(7) (l - 10)*(l - 15) = 0

Solving for l we get 2 solutions:

l₁ = 10, l₂ = 15

Using (1) to find w:

w₁ = 15, w₂ = 10

The two solutions are equivalent. The garden has dimensions 10m and 15m.

G(x)=x3+6x2+12x+8 when x=-1
beks73 [17]
G=38
Whenever you divide or multiply by one the number stays the same, therefore just take out all the xs and then solve the equation. I hope this helps!
