Answer:

u = vector (-6 , -6)

Step-by-step explanation:

u = vector(a , b)

Left (-) 6 units and down (-) 6 units

The translation vector for the image is (-6,-6).

A translation vector is a type of transformation that moves a figure in the coordinate plane from one location to another. Vectors are given in the form ( x y ) where x is the movement horizontally and y is the movement vertically.

For the given situation,

The image of a point (1, 2) under a translation is (-5, -4) .

The translation vector can be found by calculating the movement horizontally and vertically as

⇒ [tex](-5-1,-4-2)[/tex]

⇒ [tex](-6,-6)[/tex]

Hence we can conclude that the translation vector for the image is (-6,-6).

Answer:

[tex]\displaystyle t=-25\log\left(\frac{20}{30}\right)[/tex]

Step-by-step explanation:

Logarithms

The model that predicts the percentage of voters (V) as a function of the number of years (t) is:

[tex]V(t)=100-30\cdot e^{-0.04t}[/tex]

It's required to find in how many years the value of V will be V=80%. The equation to solve is:

[tex]100-30\cdot e^{-0.04t}=80[/tex]

Subtracting 100:

[tex]-30\cdot e^{-0.04t}=80-100=-20[/tex]

Dividing by -30:

[tex]\displaystyle e^{-0.04t}=\frac{20}{30}[/tex]

Applying logs:

[tex]\displaystyle \log( e^{-0.04t})=\log\left(\frac{20}{30}\right)[/tex]

For logs property:

[tex]\displaystyle -0.04t\log(e)=\log\left(\frac{20}{30}\right)[/tex]

log(e)=1. Solving for t:

[tex]\displaystyle t=\frac{\log\left(\frac{20}{30}\right)}{-0.04}[/tex]

Since 0.04=1/25:

[tex]\boxed{\displaystyle t=-25\log\left(\frac{20}{30}\right)}[/tex]

Answer:

The domain of this function is:

Domain f(t): t ≥ 0

or

Domain f(t): {x ∈ R | t ≥ 0}

Step-by-step explanation:

Given the function of the height (in cm) of the flower

f(t) = at² + bt + C

Here,

Given that height of the flower first increases and then decreases.

The current function represents the quadratic function because it is of the form. Hence, the graph would be a curve.

f(x) = ax²+ bx + c

where a, b and c are the real numbers and a≠0

Normally the domain of quadratic is the set of all real numbers, but here in this case x-values consist of the time in terms of the number of days.

As the time in terms of a number of days can not be negative. Therefore, we conclude that:

The domain of this function is:

Domain f(t): t ≥ 0

or

Domain f(t): {x ∈ R | t ≥ 0}

Answer:

The zeros are x=0,3,-2

There is a multiplicity of 1 for all of them.

Step-by-step explanation:

The required value of a is 3 for the given function.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The function is given as follows:

f(x) = 5x²– 3

Substitute the value of x = x + a in the above function,

f(x + a) = 5(x + a)²– 3

f(x + a) = 5(x² + a² + 2ax) - 3

f(x + a) = 5x² + 5a² + 10ax - 3

f(x + a) = 5x² + 10ax + 5a² - 3    ....(i)

As per the question, we have f(x + a) = 5x²+ 30x + 42     ....(ii)

Equating the equations (i) and (ii),

So, 10a = 30

a = 30/10

a = 3

Therefore, the required value of a is 3.

Answer:

x is 35

Step-by-step explanation:

the two angles are opposite so they are equal

Answer:

x = 35°

Step-by-step explanation:

Vertical Angles

When two lines cross, two pairs of angles are formed. Those who are opposed by the vertex are called vertical angles and they are always congruent.

Congruent angles have the same measure.

Thus, the angle marked as x is opposed to 35° and they have the same measure, thus:

x = 35°

Answer:

             The x intercept:    (1.5, 0)

The slope intercept form:   y = 2x - 3

                      The slope:    m = 2

Step-by-step explanation:

x intercept means y=0

4x - 2y = 6

4x - 2·0 = 6

4x = 6

x = 1.5

The slope intercept form is:  y = mx + b

4x - 2y = 6            {subtract 4x from both sides}

- 2y = - 4x + 6       {dividing both sides by (-2)}

y = 2x - 3            ← slope intercept form

Slope is the number by x, in slope intercept form of line's equation

Answer: C. Y = 8,000 + 300x

Step-by-step explanation:

Given: Initial investment = $8,000

Monthly investment = $300

Let x = the number of months since he made the initial investment.

Y= the amount in dollars that Liam has invested.

Now , Amount invested = Initial investment + (Monthly investment) x ( number of months)

Y = 8000 + 300x

Hence, the required function : Y = 8000 + 300x

So, the correct option is C. Y = 8,000 + 300x
