Answer:

Option D is the correct option.

Step-by-step explanation:

In the given question we have to identify the exponential function/geometric sequence matches the graph.

Since Options A and B are the equations of a straight line.

Option C is starts with negative notation that means the given function when graphed it's on the negative side of the y axis.

Now last option D which is in the form of $y = 2^{x}$ .We find the points lying on the graph will be (0, 1), (1, 2), (2, 4) which are mentioned in the graph.

We conclude option D is the answer.

Simplify -4b+(-9k)-6-3b+12

andre [41]

$\boxed{-7b-9k+6}$

<h2>Explanation:</h2>

We have the following expression:

$-4b+(-9k)-6-3b+12$

First of all, we need to open parentheses:

$-4b-9k-6-3b+12$

Next, combine like terms:

$-4b-3b-9k-6+12 \\ \\ \therefore \boxed{-7b-9k+6}$

the radius of the inner white circle of the doughnut is 2cm. The circumference of the outer edge of the doughnut is 43.96cm. Wha

Elenna [48]

Answer:

141.4 sq cm

Step-by-step explanation:

to find the area of the outer circle with a smaller circle inscribed within, you find the area of each and subtract the smaller area from the larger

the radius of the smaller circle is 2

we have to find the radius of the larger circle so we use what we know about its circumference:

C = 2πr

43.96 = 2πr

21.98 = πr

21.98 / π = r

r ≈ 7 cm

now use r = 7 to find area of larger circle:

A = πr²

A = π49

Area of smaller circle: 4π

Area of larger circle without including inner section is 49π - 4π = 45π

45π ≈ 141.4 sq cm

A student performed the following steps to find the solution to the question x^2 - 2x - 15 = 0. Where did the student go wrong?

nataly862011 [7]

Answer:

D In step 3

Step-by-step explanation:

Given polynomial: x² - 2x - 15 = 0

Step 1: factor the polynomial ⇒ (x + 3)(x - 5) = 0

Step 2: x + 3 = 0 and x - 5 = 0

Step 3: x = -3 and x = 5

x - 5 = 0

Add 5 to both sides:

⇒ x - 5 + 5 = 0 + 5

⇒ x = 5

Find the least whole number that can replace blank 80 to make the statement true. ÷ 18 > 86

sweet-ann [11.9K]

Answer:

649

Step-by-step explanation:

Given the expression :

__ ÷ 18 > 86

Let blank = y

y ÷ 18 > 36

y / 18 > 36

Multiply both sides by 18

(y / 18) * 18 > 36 * 18

y > 648

Hence, the least whole number which can make the statement true is (648 + 1) = 649
