if h (x) = -4x^2 + 3x + 10, find h (-2)​

Answers

Answer 1

Answer:  -12

Step-by-step explanation:

Input -2 into the function for where you see x and solve to find out what h(-2) is

h(-2) = -4(-2)^2 + 3(-2) +10  

h(-2) = -4(4) -6 + 10

h(-2) = -16 -6 +10

h(-2) = -22 + 10

h(-2) = -12

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.

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

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

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

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.

Have a NICE day

The larger number is 77 and the smaller number is 20.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, The sum of two numbers is 97.

Assuming the numbers to be a and b.

∴ a + b = 97...(i)

Also given, The larger number is three less than four times the smaller number,

Assuming the larger number to be a, therefore a = 4b - 3...(ii)

Substituting the value of a in eqn(i) we get,

4b - 3 + b = 97.

5b = 100.

b = 20, hence a = 77.

2a+1=345

2a=345-1

2a=344

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

that amount of water.

Answers

Answer:

B: 2800 hydrogen atoms

C: 6760 hydrogen atoms

D: y=amount of oxygen atoms*2

Step-by-step explanation:

B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.

C: Same thing as B. 3380*2=6760

D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.

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.
