Martin is the answer

Step-by-step explanation:

Incorrect - Martin is putting in $25 a week which means each week his bank is growing by exactly $25

Correct - Cali's pay is exponential since it is increasing each year by a percentage, so not a steady rate.

Incorrect - The athlete's weight is decreasing, so the opposite of growth.

Incorrect - And mei-lin can change how many hours she works so she will get a different amount for the time she works each day.

Macie waters 5 plants. She uses [tex]\frac{2}{3}[/tex] cup of water for each plant. So, she uses 3.33 cups of water. This problem is based on the principle of multiplication.

The principle of multiplication states that a number when multiplied by another number results in a product of the two numbers. These two numbers on being multiplied give a unique number and that resultant number is said to be divisible by both numbers and their factors.

It is given that Macie waters 5 plants.

According to the question, she uses [tex]\frac{2}{3}[/tex] cup of water for each plant.

Total number of cups of water used by her [tex]= 5\times\frac{2}{3}[/tex]

                                                                        [tex]= \frac{10}{3}[/tex]

                                                                        [tex]= 3.33[/tex].

So, Macie uses 3.33 cups of water.

Answer: his percent of increase = 66.66%

Step-by-step explanation:

percent of increase = Increase/ Previous goal x 100

Previous goal = 3 goals

Yesterday's goal = 5 goals

Percent of increase = (5-3) / 3 x 100

=2/3 x 100

=0.6666 x 100

Answer:

26.69

Step-by-step explanation:

The question lacks the required diagram. Find the diagram attached

The missing side is x;

From the triangle we are given;

Opposite = x

Hypotenuse = 29

Angle of elevation = 67 degrees

Using the SOH CAH TOA identity;

Sin theta = opposite/hypotenuse;

sin 67 = x/29

x = 29sin67

x = 29(0.9205)

x = 26.69

Hence the length of the missing side is 26.69

All trigonometric ratios of triangle PQR were calculated.

In the given right triangle PQR

PR = 14

QR = 50

So, using Pythagoras' theorem

PQ = 48

Sine of an angle = Opposite side / Hypotenuse

cosine of an angle = Adjacent side/ Hypotenuse

Tangent of an angle = Opposite side/ Adjacent side

So, SinQ = 14/50 =7/25      

CosecQ = 1/SinQ = 25/7

CosQ= 48/50 = 24/25

SecQ = 1/CosQ = 25/24

TanQ = 14/48 = 7/24

CotQ = 1/tanQ = 24/7

SinR=24/25

CosecR = 1/SinR= 25/24

CosR=7/25

SecR = 1/Cosr = 25/7

TanR =24/7

CotR = 1/tanR = 7/24

Thus, All trigonometric ratios of triangle PQR were calculated.

Step-by-step explanation:

The formula for the area of a triangle is BH1/2

The word problem gives you the area and the height

Set the problem:

369.25= 42.4(1/2)(B)

42.4(1/2)=21.2

369.25=21.2B

Divide both sides by 21.2 to isolate the variable

Answer:

The average rate of change over the given interval is 12

Step-by-step explanation:

Here, we want to calculate the average rate of change over the given interval

Mathematically, we can calculate the average rate of change using the formula below;

f(b) - f(a)/b-a

The f values are same as the y values

Thus, we have it that;

a = 1 and b = 3

f(a) = -5 and f(b) = 19

The average rate of change is thus;

(19-(-5))/(3-1) = 24/2 = 12

630 = 21t

What is 630 / 21... = 30

t = 30

Answer:

21/15=42/t

Rewrite the equation as 42/t=21/15.

42/t=21/15

Cancel the common factor of 21 and 15.

42/t=7/5

Multiply the numerator of the first fraction by the denominator of the second fraction. Set this equal to the product of the denominator of the first fraction and the numerator of the second fraction.

Answer:

The odds are 12

Step-by-step explanation:

The odds of rolling an odd number from the sum of two rolls requires that we roll one even number from one die and an odd number from another die.

Thus the probability of the event is P(e) = 1/12.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

For the given situation,

The sample space for rolling two 6 sided dice is

[tex]s[/tex] = { [tex](1,1),(1,2),(1,3),(1,4),(1,5),(1,6)[/tex]

[tex](2,1),(2,2),(2,3),(2,4),(2,5),(2,6)[/tex]

[tex](3,1),(3,2),(3,3),(3,4),(3,5),(3,6)[/tex]

[tex](4,1),(4,2),(4,3),(4,4),(4,5),(4,6)[/tex]

[tex](5,1),(5,2),(5,3),(5,4),(5,5),(5,6)[/tex]

[tex](6,1),(6,2),(6,3),(6,4),(6,5),(6,6)[/tex]}

So, [tex]n(s)=36[/tex]

Let the event be the probability that the sum is odd and the number on one of the dice is a 5

Consider that the probability that the sum is odd be a,

[tex]a =[/tex] { [tex](1,2),(1,4),(1,6),(2,1),(2,3),(2,5),(3,2),(3,4),(3,6),\\[/tex]

[tex](4,1),(4,3),(4,5),(5,2),(5,4),(5,6),(6,1),(6,3),(6,5) }[/tex] }

Consider that the probability that the number on one of the dice is 5 be b,

[tex]b=[/tex] { [tex](1,5),(2,5),(3,5),(4,5),(5,5),(6,5)[/tex] }

The probability of the event can be find by taking intersection of a and b

⇒[tex]e=a[/tex]∩[tex]b[/tex] = { [tex](2,5),(4,5),(6,5)[/tex] }

⇒[tex]n(e)[/tex] [tex]=3[/tex]

Probability (event )=[tex]\frac{n(e)}{n(s)}[/tex]

⇒[tex]p(e)=\frac{3}{36}[/tex]

⇒[tex]p(e)=\frac{1}{12}[/tex]

Hence we can conclude that the probability of the event is P(e) = 1/12

Answer:

I think it would be C

I'm not completely sure though!

Answer:

C) The graph opens down and the vertex is a maximum.

Step-by-step explanation:

Just took the quiz on K12, good luck! :)

Option (C) will be the correct option.

         f(x) = ax² + bx + c

         Vertex of the parabola is represented by [tex][-\frac{b}{2a}, f(\frac{b}{2a})][/tex]

         And the sign of the leading coefficient decides the opening of the

         parabola.

         For positive sign of 'a' → Parabola will open upwards

         For negative sign of 'a' → Parabola opens downwards

Quadratic function given in the question is,

f(x) = -4x²+ 6x - 7

Leading coefficient → (-4)

Negative sign represents the opening of the parabola downwards.

And the vertex will be a maximum.

           Therefore, Option (C) will be the correct option.
