Solve for a.

a+(−7)=−17

Answers

Answer 1

Answer: a= (-10)

Step-by-step explanation:

step 1- move the -7 to the other side of the equal sign to combine with -17.

step 2- to do this we need to make -7 positive so instead of (-17) -7, it would be (-17) +7.

step 3- leaving you with

a= (-10) hope this helped :)

The quadratic function

Answers

After solving, the maximum height of the ball is 90.25 feet.

In the given question,

A person standing close to the edge on top of a 48-foot building throws a ball vertically upward.

The quadratic function

h(t) = -16t^2+52t + 48 models the ball's height about the ground, h(t) in feet, t seconds after it was thrown.

We have to find the maximum height of the ball.

Height is given that;

h(t) = -16t^2+52t + 48

Now comparing the given equation by the standard equation ax^2+bx+c=0

Here b = 52, a = -16

For maximum height put t= -b/2a

t = -52/2(-16)

t = 52/32

t = 1.625

Maximum height

h(1.625) = -16(1.625)^2+52(1.625) + 48

h(1.625) = -42.25+ 84.5 + 48

h(1.625) = 90.25 feet

The maximum height of the ball is 90.25 feet.

Answers

The volume of water that runs off the Shoppes at Fremont parking lot after a 5 cm rainfall event is [tex]1000m^{3}[/tex].

Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies. Volume is measured in cubic units like m3, cm3, in3, etc.

Volume is sometimes referred to as capacity. For instance, a cylindrical jar's volume can be used to calculate how much water it can hold.

Basically, the volume of a liquid is measured in liters, where 1 liter is equal to 1000 cubic centimeters.

1 liter = 1000 cubic centimeters = 0.001 cubic meters

Hence,

1 cubic meters = 1000 liters

Given,

[200m x 100m = [tex]20000m^{2}[/tex]]

[5cm x 1m/ 100cm = 0.05m]

Answers

The antenna's height is determined to be 10 m using right triangle relations.

What are the relations in a right triangle?

Following are the relationships in a right triangle:

The sine of an angle is equal to the length of the hypotenuse divided by the length of the side opposite the angle.

The cosine of an angle is equal to the neighboring side's length divided by the hypotenuse's length.

The tangent of an angle is calculated by dividing the length of the angle's adjacent side by its opposite side.

So, n this case, the side opposite to the 17o angle is the vertical height from her eyes to the top of the antenna, and the next side is the horizontal distance of 29 m, then:

tan 17° = h/29

h = 29 tan 17°

h = 8.87

Including eye height:

h = 8.87 + 1.51 = 10.38 m.

The antenna is 10 meters tall, rounded to the nearest meter.

Therefore, the antenna's height is determined to be 10 m using right triangle relations.

trying to find the arc length of the arc for the polar curve r=8cosθ between 0 and π4

Answers

Answer:

Step-by-step explanation:

To find the arc length of the polar curve r = 8cosθ between 0 and π/4, we can use the formula for arc length:

L = ∫a^b √(r^2 + (dr/dθ)^2) dθ

Substituting in the values for r and dθ, we get:

L = ∫0^(π/4) √(8^2cos^2θ + (-8sinθ)^2) dθ

= ∫0^(π/4) √(64cos^2θ + 64sin^2θ) dθ

= ∫0^(π/4) √(64) dθ

= ∫0^(π/4) 8 dθ

= 8(π/4 - 0)

= 8π/4

= 2π

Therefore, the arc length of the polar curve r = 8cosθ between 0 and π/4 is 2π.

Take 85 from both sides

-85=-16t2

To get t term on its own

Divide both sides by -16

5.3=t2

We have to solve for t squared that means we must take the square root of both sides

When the card is a jack, there is a 0.25 probability that you will receive a spade.

What is probability?

The ratio of good outcomes to all possible outcomes of an event is known as the probability.

The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an event can be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

In order to better grasp probability, let's look at a straightforward application. Let's say we need to forecast if it will rain or not. Either "Yes" or "No" is the appropriate response to this query.

There is a chance that it will rain or not. Here, probability can be used. Using probability, one may forecast the results of a coin toss, a roll of the dice, or a card draw.

According to our question-

P(Spade) = 13/52 = 1/4 P(Jack) = 4/52

= 1/13 P(Spade and Jack)

= (1/4)(1/13) = 1/52 P(Spade/Jack)

= P(Spade and Jack)/P(Jack)

= (1/52)/(1/13) = (1/52)(13/1)

= 13/52 = 1/4 = 0.25

Hence, When the card is a jack, there is a 0.25 probability that you will receive a spade.
