1a and 1b question what is the quadrant function

Answers

Answer:

a). Function is not a quadratic function

b). Quadratic function.

Step-by-step explanation:

1.a). x        y         Ist difference     IInd difference

     -2      -1                 -                             -

     -1        0           0 - (-1) = 1                    -

      0       4            4 - 0 = 4              [tex]d_1[/tex] = 4 - 1 = 3

      1        9            9 - 4 = 5              [tex]d_2[/tex] = 5 - 4 = 1

      2       15          15 - 9 = 6             [tex]d_3[/tex] = 6 - 5 = 1

Since, 2nd difference [tex]d_1[/tex], [tex]d_2[/tex] and [tex]d_3[/tex] from the table are not common, function represented by the table is not a quadratic function.

b). -3x²+ x = y - 11

   -3x² + x + 11 = y

    y = -3x² + x + 11

Since, the highest degree term of the given function is of 2nd degree given function is a quadratic function.

HELP 50 POINTS Solve the system of equations using either the linear combination method or the substitution method. SHOW ALL STEPS! I need help badly. 2x + 5y = 1 -3x + 4y = -13

Answers

Step-by-step explanation:

2x + 5y = 1 and -3x + 4y = -13

From equation 1, 2x = 1 - 5y, x = 0.5 - 2.5y.

Substitute into equation 2:

-3(0.5 - 2.5y) + 4y = -13

-1.5 + 7.5y + 4y = -13

11.5y = -11.5

y = -1.

We know that x = 0.5 - 2.5y = 0.5 - 2.5(-1) = 3

Hence x = 3, y = -1.

Step-by-step explanation:

The surface area of a cylinder can be represented as [tex]2\pi rh+2\pi r2[/tex]. Let's represent pi as 3.14 and r is 5 and h is 8.

[tex](2\cdot 3.14\cdot 5\cdot8) + (2\cdot 3.14 \cdot 5^2)\\\\251.2 + 157 = 408.2[/tex]

This means the surface area of this cylinder is 408.2 in².

#3 The question says the sun of two consecutive integers is 345. What are the integers?
#5 The sum of two consecutive even integers is 446. What are the two.integers?
Need help please ​

Answers

Step-by-step explanation:

#3 let the two consecutive integers be a, a+1.

a+a+1=345

2a+1=345

2a=345-1

2a=344

a=344/2=172...

the integers are 172, 173

#5 let the consecutive even integers be a, a+2

a+a+2=446

2a=446-2

2a=444

a=444/2=222..so the even integers are 222, 224

What is the scale if: 50 km in the actual distance correspond to 4 cm on the map?

Answers

The scale is  1 cm: 12.5 km

To get this answer, you start off with the ratio 4 cm: 50 km which is given to us. It means that 4 cm corresponds to 50 km.

Divide both parts of the ratio by 4

4/4 = 1

50/4 = 12.5

The ratio 4 cm: 50 km simplifies to 1 cm: 12.5 km

1 cm on paper represents 12.5 km in real life.

The scale is 1cm on map represents 12.5 km in actual distance.

How to calculate the scale factor?

Suppose the initial measurement of a figure was x units.

And let the figure is scaled and new measurement is of y units.

Since the scaling is done by multiplication of some constant, that constant is called scale factor. Let that constant be 's'.

Then we have:

[tex]s \times x = y\\s = \dfrac{y}{x}[/tex]

Thus, scale factor is the ratio of the new measurement to the old measurement.

The ratio 4 cm: 50 km which is given to us means that 4 cm corresponds to 50 km.

Divide both parts of the ratio by 4;

4/4 = 1

50/4 = 12.5

Thus, The ratio 4 cm: 50 km simplifies to 1 cm: 12.5 km

Therefore, 1 cm on paper represents 12.5 km in real life.

These are Literal Equations. Solve for g: aeg=10.​

Answers

Answer:

g = 10/(ae)

Step-by-step explanation:

When variables are shown like that, in reality they are multiplied:

aeg = 10 is the same as a * e * g = 10

Isolate the variable, g. Note the equal sign, what you do to one side, you do to the other. Simply divide variables a & e from both sides:

(aeg)/ae = (10)/ae

g = 10/ae

g = 10/(ae) is your answer.

A quarterback is sacked for a loss of 4 yards. On the next play, his team loses 10 yards. Then the team gains 12 yards on the third play. Write an addition expression to represent the situation. Then find the sum and explain its meaning.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the question:

Play 1: Quarterback was sacked for a loss of 4 yards

Play 2 : Another loss of 10 yards

Play 3: a gain of 12 yards

Write an addition expression to represent the situation. Then find the sum and explain its meaning.

A loss of 4 yards = - 4

Loss of 10 yards = - 10

Gain of 12 yards = + 12

Addition expression for the scenario :

(-4) + (-10) + 12

Result :

-4 + (-10) + 12

= - 4 - 10 + 12

= - 14 + 12

= - 2

Hence, after two consecutive losses of 4 and 10 yards, the team wins 12 yards on the third play and the aggregate yards lost is reduced to 2 yards.

A triangle has a sides (x) feet, (x+3) feet, and (x+5) feet. The perimeter is 99.5 feet What is the measure for the largest side?

Answers

Answer:

35.5 feet

Step-by-step explanation:

x + x + 3 + x + 5 = 99.5

3x + 8 = 99.5

3x = 91.5

x = 30.5

Largest side = (x+5)

30.5 + 5 = 35.5 feet

Jacques is standing 1200 meters from a cliff he is planning to climb. The angle of elevation from the ground to the top of the cliff is 35º. To the nearest meter, how tall is the cliff?

Answers

Answer:

840 m

Step-by-step explanation:

Please refer to the attached photo.

In the attached photo, h is the height of the cliff.

The following data were obtained from the attached photo:

Opposite = h

Adjacent = 1200

θ = 35 °

The height, h of the cliff can be obtained by using the Tan ratio as follow:

Opposite = h

Adjacent = 1200

θ = 35 °

Tan θ = Opposite /Adjacent

Tan 35 = h/1200

Cross multiply

h = 1200 × Tan 35

h = 1200 × 0.7

h = 840 m

Therefore, the cliff is 840 m tall.

What is the slope of a line perpendicular to the line whose equation is
x+ 2y = –16. Fully reduce your answer.

Answers

Answer:

slope = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + 2y = - 16 ( subtract x from both sides )

2y = - x - 16 ( divide all terms by 2 )

y = - [tex]\frac{1}{2}[/tex] x - 8 ← in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2
