−5/8+(−8/5)<br><br> what does it equal?

mixer [17]

-89/40. First, u need to make a common denominator. In this case, u should use 40. Multiply he first term by 5, which get u -25/40. Multiply the second term by 8, which gets u -64/40. Now add the 2 negatives: -25/40 + (-64/40) u get -89/40

Answer:

Part A

Yes

Part B

He will land at a point 30 meters from Cannon

Step-by-step explanation:

Part A

The given function that represent the path of the Cannon, which is the path of a parabolic arc, is presented as follows;

f(x) = -0.05·(x² - 26·x - 120)

We note that the height, 'h', of the path of a parabola at a horizontal distance, 'x' from the origin is equal to f(x)

Therefore, given that at the ground level, at the start and end of the flight, the f(x) = 0, we can write;

-0.05·(x² - 26·x - 120) = 0

∴ x² - 26·x - 120 = 0

x = (26 ± √((-26)² - 4 × 1 × (-120)))/(2 × 1)

Which gives;

x = 30 or x = -4

Therefore, he lands at a point 30 meters from the starting point

Therefore, the function gives enough information to tell where he will land

Part B

He lands at the point, x = 30 from the point the cannon was fired.

at the mall the cost of a pretzel is $2 less than the cost of some ice cream. five ice creams cost the same as nine pretzels. fi

Elanso [62]

Cost of one pretzel is $2.5 and cost of one ice cream is $4.5

Step-by-step explanation:

Let,

Cost of pretzel = x

Cost of ice cream = y

According to given statement;

the cost of a pretzel is $2 less than the cost of some ice cream.

x = y - 2 Eqn 1

five ice creams cost the same as nine pretzels.

9x = 5y Eqn 2

Putting value of x from Eqn 1 in Eqn 2

$9(y-2)=5y\\9y-18=5y\\9y-5y=18\\4y=18$

Dividing both sides by 4

$\frac{4y}{4}=\frac{18}{4}\\y=4.5$

Putting y=4.5 in Eqn 1

$x=4.5-2\\x=2.5$

Cost of one pretzel is $2.5 and cost of one ice cream is $4.5
