Answer:

Width of the archway at its base: 11 units, height of the archway at its highest point: 30.25 units.

Step-by-step explanation:

The graph that represents the equation y = -x^{2} + 5\cdot x + 24 is now sketched with the help of a graphing tool and whose representation is included in a file attached below. The point associated with x-intercepts are (-3, 0) and (8, 0) and the point associated with the highest point is (2.5, 30.25). The width of the archway at its base (\Delta x) and the height of the archway at its highest point (\Delta y) are, respectively:

\Delta x = 8 - (-3)

\Delta x = 11

\Delta y = 30.25

Width of the archway at its base: 11 units, height of the archway at its highest point: 30.25 units.

Angle sec0= -13/12 and cot<0. what are the exact values of tan0 and sin0.
Arturiano [62]

Answer:

tan 0= -2.4

sin 0 = 0.42

Step-by-step explanation:

sec 0 = -13/12 => cos 0 = -12/13

cot 0 < 0 => tan 0 < 0

so, the angle is on second quadrant

=> tan 0 = -12/5 = -2.4

=> sin 0 = 5/12 = 0.42

Answer:

D. Expression for Nick's distance from starting point= 6+(-4)+2

Step-by-step explanation:

Finding expression for each scenario:

A.

Number of boxes processed on on Monday =6 boxes

Number of boxes processed on on Tuesday =4 boxes

Number of boxes processed on on Wednesday =2 boxes

Expression for total boxes processed on these 3 days = 6+4+2

B.

Temperature of Suma's city at noon = 6°C

Temperature of Suma's city at 8pm = 4°C

Temperature of Suma's city at noon next day =  2°F

Total temperature change = cannot be determined as all measurements are not in same units.

C

Money put on Monday = $6

Money put in Wednesday =$4

Money withdrew on Saturday = $2

Expression for balance of Re'onna's piggy bank = 6+4-2

D

Distance ran north =6 miles

Distance ran south(back) = 4 miles

Distance  ran north again = 2 miles

Expression for Nick's distance from starting point= 6+(-4)+2

Determine whether each relation is a function. Give the domain and range for each relation.
brilliants [131]

Answer:

Not a function

Domain: {3,4}

Range: {4,5}

Step-by-step explanation:

A function is a relation where each input has its own output. In other words if the x value has multiple corresponding y values then the relation is not a function

For the relation given {(3, 4), (3, 5), (4, 4), (4, 5)} the x value 3 and 4 have more than one corresponding y value therefore the relation shown is not a function

Now let's find the domain and range.

Domain is the set of x values in a relation.

The x values of the given relation are 3 and 4 so the domain is {3,4}

The range is the set of y values in a relation

The y value of the given relation include 4 and 5

So the range would be {4,5}

Notes:

The values of x and y should be written from least to greatest when writing them out as domain and range.

They should be written inside of brackets

Do not repeat numbers when writing the domain and range
