what is the vertex of y = −(x + 4)2 − 7

ANSWER

-4.0

EXPLANATION

The given trigonometric equation is

[tex] \tan \: 45 \degree - 10 \: \cos \: 60 \degree[/tex]

From special angles or using the unit circle.

[tex]\tan \: 45 \degree = 1[/tex]

[tex] \cos \: 60 \degree = \frac{1}{2} [/tex]

We make the substitution to get:

[tex]1 - 10 ( \frac{1}{2} ))[/tex]

This simplifies to:

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

Hence the correct answer is -4.0

Answer:

18

Step-by-step explanation:

9 + 9 = 18

Answer:

It equals 18.

Step-by-step explanation:

Nine is worth 9 1's.

Nine is also worth 9 1's.

So if you count up all the 1's, it will equal 18.

Jacob bought 3 medium and 6 large pizzas for his class party, as the large pizzas were twice the amount of medium pizzas and the total number was 9.

Jacob bought a total of 9 pizzas for his class party. The condition given is that the amount of large pizzas was twice the amount of medium pizzas. Let's define the number of medium pizzas as x. Therefore, the amount of large pizzas would be 2x. Since the total number of pizzas is 9, we can write the equation x + 2x = 9. Adding the terms together gives us 3x = 9. Dividing both sides of the equation by 3, we find that x = 3. This means Jacob bought 3 medium pizzas and 2 times 3, which is 6 large pizzas for his class party.

Answer:

The slope of the line y=3 is 0

Step-by-step explanation:

We need to find the slope of the line y =3

the general form of the equation is

y = mx+b

where m is the slope and b is the y-intercept.

Looking at the given equation

y=3

We can write it as

y =0(x) + 3

So, the slope of the line y=3 is 0

Answer:

The slope is 0

Step-by-step explanation:

Note that [tex]y = 3[/tex] is the equation of a horizontal line that intersects the y-axis at point (0, 3).

The slope of a line is a measure of how the variable y varies when x increases or decreases. In this case, the variable y always has the same value. Therefore the slope is zero.

All horizontal lines have slope [tex]m = 0[/tex]

Answer:

Perimeter: 174.8 m

Area: 1,394 sq m

Step-by-step explanation:

First, the perimeter.

Before we start, let's calculate the circumference of the half-circles at the ends of the field.

The measurement says 2,000 cm, so let's convert it to 20 m for ease.

Circumference of a circle: πd, where d = diameter.. in our case d = 20 m

Circumference of a 20m diameter circle: 20π = 62.8 m

We have 2 half circles... so the perimeter of each half-circle will be: 31.4 m

We also have 800 cm measurement for the "height" of the seating areas... let's convert that in 8 m

We also need to find out the space between the seating area...  We know the whole rectangular pitch is 40 m, then we have to subtract the width of both seating areas (20 and 15 m)... so the space between them is 5m

So, starting with the upper left corner of the rectangular pitch, and working our way clockwise, we encounter the following lengths:

P = 40 + 31.4 + 8 + 10 + 8 + 5 + 8 + 25 + 8 + 31.4 = 174.8 m

The total perimeter is then of 174.8 m

For the area, we need to calculate the area of all forms:

Large rectangular pitch:

LR = 40 x 20 = 800 sq m

The two half circles, form a circle, so A = πr², where r is the radius, which is half the diameter.

AC = π (10)² = 100 π = 314 sq m

Then the seating areas:

SA1 = 25 x 8 = 200 sq m

SA2 = 10 x 8 - 80 sq m

Then, we add up everything:

TA = LR + AC + SA1 + SA2

TA = 800 + 314 + 200 + 80 = 1,394 sq m

The answer to your question is b.

Answer:

Step-by-step explanation:

a1 = 6

a2 = -1.2*a_(n-1)

a2 = -1.2*a_1

a2 = -1.2 * 6

a2 = -7.2

a3 = -1.2*a_(n-1)

a3 = -1.2*a_2

a3 = -1.2 * - 7.2

a3 = 8.64

a4 = -1.2 * a_3

a4 = -1.2 * 8.64

a4 = -10.368

Answer:  The correct option is (B) -10.368.

Step-by-step explanation:  Given that a sequence is defined b the following :

[tex]a_1=6,~~~a_n=-1.2a_{n-1}.[/tex]

We are to find the 4-th term.

To find the fourth term, we need to start from finding the first term.

If n = 2, then the second term is given by

[tex]a_2=-1.2\times a_1=-1.2\times 6=-7.2.[/tex]

If n = 3, then the third term is given by

[tex]a_3=-1.2\times a_2=-1.2\times (-7.2)=8.64.[/tex]

If n = 4, then the fourth term is given by

[tex]a_4=-1.2\times a_3=-1.2\times 8.64=-10.368.[/tex]

Thus, the fourth term of the given sequence is -10.368.

Option (B) is CORRECT.

The probability of a dart (thrown at random) landing in the area marked F is:

                                      1/16

We know that the probability of an outcome is defined as the chance of occurrence of an outcome and it is calculated as the ratio of number of favorable outcomes to the total number of outcomes.

We first make equal sections i.e. we divide the figure into equal sections and observe that:

A and D is made up of 4 sections.

B,C and E is made up of 2 sections.

F and G are made up of 1 section.

This means that the total number of sections are: 4+4+2+2+2+1+1=16

Hence,

Probability(landing on F)=1/16

( Since there are total 16 sections and F is made up of 1 )

Answer:

3.6 fl oz

Step-by-step explanation:

figure out the percentage of the gallon that was used in the original ratio, in this case 1 that was used in 1.5. thats 150%

so no multiply 2.4 by 1.5 to get 3.6

to check work divide both ratios and see if its the same number (i checked)

For 1.5 gallons of gasoline, you should add 3.6 fluid ounces of oil to maintain the required ratio of 2.4 fl oz of oil per gallon of gas.

To calculate how much oil is needed for 1.5 gallons of gasoline when the mixture requires 2.4 fl oz of oil per gallon of gasoline, one can use a simple proportion:

2.4 fl oz oil / 1 gallon of gas = x fl oz oil / 1.5 gallons of gas

Solve for x to find the amount of oil needed for 1.5 gallons of gas:

x = 2.4 fl oz oil * 1.5 gallons of gas

We can multiply 2.4 fl oz by 1.5 to get the amount of oil:

x = 3.6 fl oz oil

Therefore, you should add 3.6 fluid ounces of oil to your 1.5 gallons of gasoline to achieve the correct mixture.

For this case we have by definition, that the sum of the internal angles of a triangle is 180 degrees.

Then, according to the figure we have to:

[tex]x + y + y = 180[/tex]

Where "x" represents the angle of the left side of the triangle, we have that "x" is given by:

[tex]x = 180-114\\x = 66[/tex]

So we have to:

[tex]66 + 2y = 180\\2y = 180-66\\2y = 114\\y = \frac {114} {2}\\y = 57[/tex]

Finally, "y" is equal to 57 degrees.

Answer:

Option C

The value of y in the triangle is,

⇒ y = 57 degree

For this case we have by definition, that the sum of the internal angles of a triangle is 180 degrees.

Then, according to the figure we have to:

⇒ x + y + y = 180

Where "x" represents the angle of the left side of the triangle, we have that "x" is given by:

x = 180 - 114

x = 66 degree

So we have to:

66 + 2y = 180

2y = 180 - 66

2y = 114

y = 57 degree

Value of h is 4.5 unit.

Step-by-step explanation:

Given:

MO = 12 and PO = 2

∠N and ∠p are right angle

To find: Value of h.

In ΔMNO and ΔONP

∠MNO = ∠OPN = 90°

∠MON = ∠NOP  ( common angle)

⇒ ΔMNO and ΔONP are similar triangle by AA Similiarity criteria.

Corresponding part of similar triangles are ,

∠OMN = ∠ONP

[tex]\frac{OM}{ON}=\frac{MN}{PN}=\frac{ON}{OP}[/tex]

Consider,

[tex]\frac{OM}{ON}=\frac{ON}{OP}[/tex]

[tex]OM\times OP=ON^2[/tex] .................(1)

Now in ΔONP,

using Pythagoras Theorem

ON² = NP² + OP²

ON² = h² + 2²

ON² = h² + 4 .............(2)

From (1) and (2), we have

12 × 2 = h² + 4

h² = 24 - 4

h² = 20

[tex]h=\sqrt{20}[/tex]

[tex]h=2\sqrt{5}[/tex]

h = 2 × 2.236  ( Value of √5 is 2.236 )

h =  4.472

h = 4.5 unit

3x - 13y = 2 ; solve for y.

In order to solve for y, we must isolate it by getting it onto its own side. We can do this by subtracting 3x from both sides.

-13y = -3x + 2

Then, divide both sides by -13.

-13y ÷ -13 = (-3x + 2) ÷ -13

The percentage of pastrami sold was 40 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Number of sandwiches sold in one day = 90

Number of pastrami in 90 sandwiches = 36

To calculate the percentage of pastrami in sandwiches , we divide the total number pastrami to the total number of sandwiches and multiply by 100

So , percentage of pastrami = ( 36 / 90 ) x 100 %

                                               = ( 4 / 10 ) x 100 %

                                               = 4 x 10 %
