Step-by-step explanation:

The total amount Sam will pay in all will be $2,400,000

From the question, we are to determine the interest Sam pays in all

Using the simple interest formula,

I = PRT

From the given information,

P = $2,000,000

R = 5% = 0.05

T = 4

Putting the parameters into the formula,

I = $2000000 × 0.05 × 4

I = $400000

The interest Sam will pay is $400,000

The total amount Sam will pay in all will be $2,000,000 + $400,000

= $2,400,000

Hence, the total amount Sam will pay in all will be $2,400,000

Answer:

x ≤ 1/2

Step-by-step explanation:

Domain:  input values (x-values)

We cannot take a square root of a negative number, therefore

3 - 6x ≥ 0

Solving the inequality:

⇒ 3 - 6x ≥ 0

⇒ 3 ≥ 6x

⇒ 1/2 ≥ x

⇒ x ≤ 1/2

Therefore, the domain is x ≤ 1/2

The value of sin⁻¹ (sin 17°) is 17° or 17 degree after applying the trigonometric identity sin⁻¹ (sinx) = x

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

= sin⁻¹ (sin 17°)

The above expression represents an angle.

Let's suppose the angle is x and sin of x is sinx

sinx is a ratio of side opposite to the angle to hypotenuse.

If we take sin inverse of sinx we get an angle of x.

sin⁻¹ (sinx) = x

sin⁻¹ (sin 17°) = 17 degree

Thus, the value of sin⁻¹ (sin 17°) is 17° or 17 degree after applying the trigonometric identity sin⁻¹ (sinx) = x

Answer:

[tex]\displaystyle \large{\cos \theta = \dfrac{-3}{\sqrt{34}} = -\dfrac{3\sqrt{34}}{34}}\\\\\displaystyle \large{\csc \theta = \dfrac{\sqrt{34}}{5}}\\\\\displaystyle \large{\tan \theta = -\dfrac{5}{3}}[/tex]

Step-by-step explanation:

Accorded to trigonometric formula, we know that:

[tex]\displaystyle \large{\cos \theta = \dfrac{x}{r}}\\\\\displaystyle \large{\csc \theta = \dfrac{1}{\sin \theta} = \dfrac{1}{\frac{y}{r}} = \dfrac{r}{y}}\\\\\displaystyle \large{\tan \theta = \dfrac{\sin \theta}{\cos \theta} = \dfrac{y}{x}}[/tex]

We know what x and y are but not yet knowing what r is. We can find r (radius) using the formula:

[tex]\displaystyle \large{r=\sqrt{x^2+y^2}}[/tex]

Input x = -3 and y = 5 in.

[tex]\displaystyle \large{r=\sqrt{(-3)^2+(5)^2}}\\\\\displaystyle \large{r=\sqrt{9+25}}\\\\\displaystyle \large{r=\sqrt{34}}[/tex]

Hence, radius is √34 and we know all we need now. Substitute x = -3, y = 5 and r = √34 in respective areas.

[tex]\displaystyle \large{\cos \theta = \dfrac{-3}{\sqrt{34}} = -\dfrac{3\sqrt{34}}{34}}\\\\\displaystyle \large{\csc \theta = \dfrac{\sqrt{34}}{5}}\\\\\displaystyle \large{\tan \theta = -\dfrac{5}{3}}[/tex]

Answer:

y = x + 1

Step-by-step explanation:

Step 1: Find the slope.

Parallel lines have the same slope. That means that the line we are seeking is going to have the same slope as line x - y = 7.

To find the slope of the line x - y = 7 let's change it to the slope-intercept form.

Slope-Intercept Form

y = mx + b

m ... slope

b ... y-intercept

Let's change the equation of the parallel line to slope-intercept form (isolate y).

x - y = 7

Add y on both sides.

x - y + y = 7 + y

x = 7 + y

Subtract 7 on both sides.

x - 7 = 7 + y - 7

x - 7 = y

y = x - 7

Let's read the slope from the equation.

Instead of y = x - 7 we can write y = 1x -7.

Now it's obvious that m (slope) is 1.

m = 1

So far, our equation of the line is:

y = 1x + b

which is te same as

y = x + b

Step 2: Find y-intercept.

To find out y-intercept (b), we substitiute the point (-7, -6) in the equation. Points are in form (x, y) so -7 is x and -6 is y.

y = x + b

-6 = -7 + b

Solve for b.

1 = b

Step 3: Substitute slope and y-intercept in general formula for slope-intercept form of the line.

Now substitute m and b in slope-intercept form y = mx + b.

m = 1

b = 1

Equation of the line:

y = x + 1

Step-by-step explanation:

This  is an equilateral triangle, therefore, all the angles  are 60 degrees.

3 times  60 is  180.

180 is the answer

Step-by-step explanation:

the domain is the set or interval of all valid x values.

the range is the set or interval of all valid y values.

1.

domain = {-1, 2, 5}

range = {0, 2, 3, 7}

function : no, because x = -1 has 2 different y values assigned (7 and 2). that violates the definition of a function.

2.

domain = {-3, -2, -1, 1, 4}

range = {-5, -1, 0, 2}

function : yes. every x bake has exactly one y value assigned.

3.

domain = {4, 6, 7}

range = {-1, 2, 3, 5}

function : no, because x = 4 has 2 different y values assigned (2 and 5).

4.

domain = [-3, 3) "3" is not included, hence the empty dot

range = [-4, 5]

function : yes

5.

domain = (-infinity, +infinity) "infinity" is not a possible value, so the limits are not included.

range = [-1, 2]

function : yes

6.

domain = [-2, +infinity)

range = (-infinity, +infinity)

function : no. except for x = -2 all x values have 2 different y values assigned.

An equation is formed of two equal expressions. The equation 7*e^0.1t=47 can be expressed as t=[ln (47/7)]/0.1.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation 7*e^0.1t=47 in terms of logarithm in terms of base-e can be solved as,

[tex]7e^{0.1t}=47\\\\e^{0.1t}=\dfrac{47}{7}\\\\0.1 t = {\rm ln}(\dfrac{47}{7})\\\\t = \dfrac{ {\rm ln}(\frac{47}{7})}{0.1}[/tex]

Answer:

59% chance

Step-by-step explanation:

Statistics from the past ten years predict that the chance of rain on any single day in April in Asha’s hometown is 41%. If Asha’s birthday is April 10, what is the chance of it not raining on Asha’s birthday?

Asha's birthday in in April. The chance of rain on any single day in April is 41%. So, there is a 41% chance of rain.

But, that's not what the problem is asking for. The problem is asking for the chance of not raining. To solve for this, we use simple algebra.

100%(all of the time) - 41%(how much it happens) = 59%

The 59% is the chance of it not raining on Asha's birthday.

Hope this helps! Happy birthday, Asha!

• Find <1

Since it is obvious that <ABD is a sum of <1 and <2:

⇒ <ABD = <1 + <2

now we know that <2 is 14° more than <1 and that <ABD = 66°

x(x-5)-9(x-5)

(x-9)(x-5)

Answer:

(x-9)(x-5)

Step-by-step explanation:

To factor this expression, you need to find two values that have a sum of -14 and also have a product of 45. The values -5 and -9 meet these requirements and become the constants in the two factors of the expression,

x2 − 14x + 45 = (x − 9)(x − 5).

The length of the chord AC in the circle is 24 units.

Chords are line segment joining any two sides of a circumference of a circle.

The radius of a circle is half of diameter of the circle.

Therefore, a radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa.

Hence, the radius that runs through M is perpendicular to the chord AC. Therefore, the chord AC is divided into two halves namely AM and MC.

Hence,

AC = AM + MC

AC = 12 + 12

AC = 24 units
