The slope of function f is - 1 and the y-intercept of f is 4.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Let Two points on the function f are (-1, 5) and (0, 4).

Now,

Since, The equation of line passes through the points (-1, 5) and (0, 4).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (4 - 5) / (0 - (-1))

m = - 1 / 1

m = - 1

Thus, The equation of line with slope - 1 is,

⇒ y - 5 = -1 (x - (-1))

⇒ y - 5 = - 1 (x + 1)

⇒ y = - x - 1 + 5

⇒ y = - x + 4

By comparing with the equation of line y = mx + b, we get;

The y-intercept of f = 4

And, The slope = - 1

Other than itself, ∠FGE is an angle that is congruent to ∠FGB.

Angles that are congruent with one another include two or more angles. This means that the dimensions of these angles are same. Angles can be acute, obtuse, exterior, or interior, and the congruence of angles is unaffected by their type. Congruent angles aren't always supplementary angles, in general. Angles must be complementary in order for the sum to be 180. Since right angles and supplementary angles have the same measure and sum up to 180, they are the only angles that can be said to be congruent.

Because ∠FGE and ∠FGB are supplementary angles, so they add up to 180 degrees. Because angle ∠FGE is 90 degrees, or a right angle, that means ∠FGB must also be 90 degrees. This makes them congruent.

What is trigonometric ratio?

The trigonometric functions in mathematics are real functions that relate the angle of a right-angled triangle to the ratios of the lengths of the two sides. All geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many others, use them extensively.

From the given diagram we have to find the value of BC and AC.

First to find the value of AC.

Consider, the trigonometric ratio

    sinθ = [tex]\frac{AC}{AB}[/tex]

sin(70°) = AC / 7

      AC = sin(70°)*7

     AC = 6.58

Now to find the value of BC.

Consider, the trigonometric ratio

cos(70°) = BC / AB

cos(70°) = BC / 7

What is sales of products?

Selling a good or service in exchange for cash, a benefit, or some other kind of payment is known as product sales. When a customer purchases a good or service that will meet their needs, the transaction is known as a product sale. The quantity of goods sold during a specific time period aids in calculating product sales.

Step by Step Explaination:

Equation that models the sales of the product

The equation that models the sales of the product after an initial release exists:

s = 12√4 + 10

where s denotes the total sales (in thousands)

t denotes the time in weeks

you want to replace the s with 150 in the equation and then just solve

for t.

150 = 12√4t + 10

Subtract 10 from both sides

150 - 10 = 12√4t + 10

140 = 12√4t

Divide both sides by 12      

11.66= √4t  

Taking square root on both sides of the equation.    

135.95 = 4t      

Now divide both sides by 4

33.98 = t (approximately).

so in 33 weeks, they will have sold 150 units.

Answer: The value of f(-1) is equal to 5(-1)^2 + (-1) + 4 = -5 + (-1) + 4 = -2

Step-by-step explanation:

To evaluate f(-1), we substitute -1 for x in the function f(x)=5x^2+x+4. This gives us f(-1)=5(-1)^2+(-1)+4. We simplify this by applying the exponent first, so (-1)^2=1. Then we substitute the result in the function, which gives us f(-1)=5(1)+(-1)+4. Now we can simplify it by adding and subtracting the values which gives us f(-1)=5+(-1)+4=8.

Answer:

If someone get a 150% salary raise, it means that the current salary will be increased by 1.5 (150/100) from the current amount.

To demonstrate this, let's assume that someone's salary is $1000, if we increase it by 150% we must calculate 150% of $1000.

[tex]1000*150\%=1000*\frac{150}{100} =1500[/tex]

150% of $1000 is $1500, since the person wll get a 150% salary raise, it means that the actual salary INCREASES that value, the final salary of a person will be:

Final salary = previous salary + amount of increase

Final salary = $1000 + $1500

Final salary = $2500
