Help with math please. Thank you!

Step-by-step explanation:

The height of the swipe card is given by :

[tex]h(t)=-3t^2+15t+18[/tex] .....(1)

We need to find the maximum height of the swipe card and the time to reach the maximum height.

For maximum height, put dh/dt = 0

So,

[tex]\dfrac{d}{dt}(-3t^2+15t+18)=0\\\\-9t+15=0\\\\t=\dfrac{15}{9}\\\\t=1.67\ s[/tex]

It will take 1.67 seconds to reach the maximum height.

Now, put t = 1.67 s in equation (1).

[tex]h(1.67)=-3(1.67)^2+15(1.67)+18\\\\=34.68\ feet[/tex]

Hence, the maximum height of the swipe card is 34.68 feet and the time to reach this height is 1.67 s.

Answer:

$324

Step-by-step explanation:

Cost per books = $20

Book cost = $20 * (9 + 6) = 20 * 15 = $300

Cost per magazine = $3

Number of magazines = 8

Magazone cost = 8 * $3 = 24

Total cost = $300 + $24

= $324

Answer:

y=1/2x²

Step-by-step explanation:

y=2x-²

y=1/2x²

The equation can be simplified to find the inverse of y = 2x² is y=1/2x², the correct option is B.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

Equation y = 2x²

Now,

To find the inverse of a function, you need to swap the x and y variables and solve for y. So, the equation that can be simplified to find the inverse of y = 2x² is x = 2y². You can simplify it by dividing both sides by 2 and taking the square root of both sides. The inverse function is y = ±√(x/2).

Therefore, by the equation the answer will be y=1/2x²

Answer:

450 x (1 + 0.5) ^ X = Phone subscribers

Step-by-step explanation:

Since a telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members, and the company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan, to determine the number of phone subscribers x months after the plan was launched, the following function must be considered and solved:

450 x (1 + 0.5) ^ X = Phone subscribers

So, for example, in 3 months, the number of subscribers would be the following:

450 x (1 + 0.5) ^ 3 = 1,518.75

Thus, in 3 months, the company would have 1,518 subscribers.

the answer is 26.88 i wish that helped :)

Answer:

angleQ+angleR is 180degrees because of the properties of isoceles trapezoid. So, if you set equation and solve, you'll get the fact that x is 12, and angleR is 130degrees, and angleQ is 50degrees. According to the properties of isoceles trapezoid, angleQ is the same as angleT. So, angleT is 50degrees

Answer:

Step-by-step explanation:

Answer:

the angle is = 50

Step-by-step explanation:

8x+2+70+60=180° (interior angles of a triangle add up to 180°)

8x+132=180

8x=180-132

8x=48

divide with the coefficient of x both sides

x=6

substitute

(8(6)+2)+70+60=180

50+70+60=180

180=180

The pair of equations below is a result of constructing the altitude, h, in Triangle ABC is A; sin C = h/a and sin A = h/c.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

We know:

[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}[/tex]

So from the attached figure;

sin C = h/a

sin A = h/c

These expressions have an h term in common. We can combine them if we can find forms of the expressions in terms;

h = a (sin C)

h = c (sin A)

Thus, option A is correct pair.
