Answer:

d = √34

Step-by-step explanation:

(-2, -1) & (3, 2)

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(3 + 2)² + (2 + 1)²]

d = √[(5)² + (3)²]

d = √(25 + 9)

d = √34

$f(x) = -x^2-7x-6$

As $x \to \pm \infty$ , $y \to - \infty$ .

This can be easily verified by looking at the graph (graph of a quadratic equation).

The growth of a population is not linear, it's exponential.

31.

Exponential growth > polynomial, so $y = 3^x$ .

$V(t) = 30\cdot (25)^{\frac{t}{20}}$

The question is asking V(t) for t = 40.

$V(40) = 30\cdot (25)^{\frac{40}{20}} \\~\\V(40) = 30\cdot 25^2 \\~\\V(40) = 30\cdot 625 \\~\\V(40) = 18750$

36.

The point of symmetry of a quadratic equation $y = ax^2+bx+c$ is at its vertice:

$V_x = \dfrac{-b}{2a}$

$V_x = \dfrac{6}{2}$

$V_x = 3$

The line is x= 3.

I’m really struggling, someone please help!

Ulleksa [173]

Hi there! :)

Answer:

$\huge\boxed{C.}$

We can examine each answer choice individually:

A. 569 × 10² = 569 × (10 · 10) = 569 · 100 = 56,900. Therefore, this choice is incorrect.

B. 569 · 10 = 5,690. This choice is incorrect.

C. 10³ · 569 = (10 · 10 · 10) ·569 = 1000 · 569 = 569,000. This choice is correct.

D. 10² · 569 = (10 · 10) · 569 = 56,900. This choice is incorrect.

Therefore, the correct option is C.

A picture frame (see figure) has a total perimeter of 3 feet. The width of the frame is 0.64 times its length. Find the dimensio

Naya [18.7K]

Answer:

$\approx 0.59\text{ ft by }0.91\text{ ft}$

Step-by-step explanation:

Let $\ell$ represent the length of the rectangle. The width can be represented as $0.64\ell$ .

The perimeter of a rectangle with lengths $l$ and $w$ is given by $p=2l+2w$ .

Thus, we have:

$2\ell+2(0.64\ell)=3,\\2\ell +1.28\ell=3,\\3.28\ell=3,\\\ell=0.91463414634\approx 0.91$

The width is then $0.64(0.91463414634)=0.58536585365\approx 0.59$ .

mr. cuddy draws a triangle with a perimeter of 36cm. Principal Aranda says that the longest side measures 18 cm, How do you know

hichkok12 [17]

Answer:

See the procedure

Step-by-step explanation:

we know that

<u>The Triangle Inequality Theorem</u>, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

a,b,c the lengths side of triangle

c is the greater side

The perimeter is equal to

P=a+b+c

P=36 cm

If c=18 cm

then

a+b=18

Applying the Triangle Inequality Theorem

a+b > c

18 > 18 ----> is not true

therefore

Principal Aranda is incorrect

The larger side cannot measure 18 cm

The largest side must be less than 18 cm
