Vector z = <5, -3> is subtracted from vector w = <-6, -5>. The magnitude of the resulting vector is approximately __
Digiron [165]

Answer:

11.18\ \text{units}

10.3^{\circ}

Step-by-step explanation:

w=

z=

z is subtracted from w so

w-z=\\\Rightarrow w-z=

Magnitude is given by

\sqrt{(-11)^2+(-2)^2}=5\sqrt{5}=11.18

The magnitude of the resulting vector is approximately 11.18\ \text{units}.

The angle is

\theta=\tan^{-1}\dfrac{-2}{-11}\\\Rightarrow \theta=10.3^{\circ}

The direction is approximately 10.3^{\circ}

the function f(x) = 3,005(1+0.03)^x represents the amount of money in a savings account where x represents time in years. what d
Stolb23 [73]

Answer:

Option d. the initial amount of money placed in the savings account

Step-by-step explanation:

we have

f(x)=3,005(1+0.03)^{x}

This is a exponential function of the form

f(x)=a(1+r)^{x}

where

a is the initial value

r is the growth rate

(1+r) is the base

x is the number of years

f(x) is the amount of money in a savings account

In this problem we have

a=$3,005

r=0.03=3%

(1+r)=1.03

therefore

3,005 represent the initial value ( the amount of money for the value of x equal to zero)

True or false please help thank you
Leni [432]

Answer:

True.

<em>See</em><em> </em><em>below</em><em> </em><em>for</em><em> </em><em>explanation</em><em>.</em><em> </em>

Step-by-step explanation:

<u>Reason</u><u> </u><u>1</u>

  • When we solve the equation by combining both equations in one, the variable will become 0.

<u>Proof</u>

\begin{cases} y = 4x - 3 \\ y = 4x - 5 \end{cases} \\ 4x - 3 = 4x - 5

Combine like terms.

4x - 4x =  - 5 + 3 \\ 0 =  - 2

See that the equation is false no matter which numbers you substitute in x-term.

<u>Reason</u><u> </u><u>2</u>

  • Both graphs are parallel and don't have any intercepts to each others.

<em>See the attachment below for graphs</em>.

Since both graphs do not really have intercepts, that means they do not provide any solutions. Hence, no solutions.

A scientist is studying the population growth rates of two different species of rats in the same laboratory conditions. The popu
Korolek [52]

Since, population of species A is represented by : P=2^{x} +19

Let us find the population of species A, at the end of week 1:

i.e., x = 1

i.e., P(1)=2^{1} +19

i.e., P(1)=2 +19

i.e., P(1)=21


Also, since population of species B is represented by : P=3^{x} +18

Let us find the population of species B, at the end of week 1:

i.e., x = 1

i.e., P(1)=3^{1} +18

i.e., P(1)=3 +18

i.e., P(1)=21


Thus, at the end of 1 week, species A and species B will have the same population.

Hence, option D is correct.
