Answer:

-2, -3, 3/2

Step-by-step explanation:

Factor 2x^2+ 3x – 9

(x+3)(2x-3)

(x + 2)(x+3)(2x-3)  - the zeros are basically the opposite of the numbers here

x+2=0

x=-2

x+3=0

x=-3

2x-3=0

x=3/2

To plot just put the numbers on the x line because it is (x,0)

Answer:

Step-by-step explanation:

What we'll do:

A method to find whether an object will float or sink in a liquid is to find it's specific gravity with respect to the liquid, The Specific Gravity tells us the percentage of object's mass which will be submerged in water

Finding the Specific Gravity:

Density of Box:

Density = Mass / Volume

Density = 80 grams / 78 cm³

Density = 1.02 grams/cm³

Specific Gravity of Box with respect to water:

Specific Gravity = Density of Box / Density of Water

we know that density of water is 1 gm/cm³, plugging the values

Specific Gravity = 1.02 / 1

Specific Gravity = 1.02

Hence, 102% of the object will be under water

Q. but I've only heard about 100% of something, how can something be more than 100%?

A. The answer is that the extra 2% over the 100% is providing to the object being even deeper underwater

Answer

A

Step-by-step explanation:

So in the diagrams we see there is 2/3 shaded into a 12  cutted square. So we multiply 4x3 to get 12. So now we have to turn the 3 into 12.

so

[tex]\frac{2}3}[/tex] x[tex]\frac{4}{4}[/tex] =[tex]\frac{8}{12}[/tex]

Since we multiplied 4 on the bottom we have to multiply 4 on the top.

Answer:

Variance =9.2983, 27.6927

Standard deviation = 3.0493, 5.2624

Step-by-step explanation:

n = 20

S = 14.75

X² = chisquare

N-1 = degree of freedom

Alpha = 0.1

Alpha/2 = 0.1/2 = 0.05

1-0.1/2 = 0.95

Using statistics table

X² 19,0.05 = 30.14

X² 19, 0.95 = 10.12

A. 19(14.75)/30.14 , 19(14 75)/10.12

= 9.2983, 27.6927 for the variance of the population

B. Standard deviation = square root of variance

= √9.2983, √27.6927

= 3.0493, 5.2624

Answer:

D

Step-by-step explanation:

6 and 3 can both be divided by 3, which gives u 2/1

Answer:

D. 2 cups of flour/1 cup of milk.

Step-by-step explanation:

Here's the definition of unit rate:

the ratio of two different units, with the denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc.

Since we need to find the unit rate, find the GCF of 6 & 3 (3). Now divide both values by 3.

(6/3)/(3/3)

2/1

The unit rate between cups of flour to cups of milk is 2:1, which is D.

Step-by-step explanation:

First you gotta write it in standard form

y - 3 = -5(x-1)

distribute -5(x-1) = -5x + 5

y - 3 = -5x + 5

  +3           +3

y = -5x + 8

Answer:

Weak Positive Correlation

Step-by-step explanation:

The r value of 0.15 indicates a weak positive correlation value because a weak correlation value is less than 0.3, anything between 0.3 and 0.7 are a moderate correlation, and anything greater than 0.7 would be a string correlation. So, since this is less than 0.3, this is a weak correlation. A positive correlation is a positive value and a negative correlation value is a negative number, so this would be a weak positive correlation value.

A value of r = 0.15 suggests a weak positive correlation, indicating a slight tendency for the variables.

As per the question, the value of r is positive (greater than 0), which suggests a positive correlation between the variables.

However, the value of 0.15 is close to 0 and relatively small, indicating a weak correlation.

This means that there is a weak tendency for the variables to increase or decrease together.

Thus, a value of r = 0.15 suggests a weak positive correlation, indicating a slight tendency for the variables to increase or decrease together, but the relationship is not strong.

Answer:

the third option: g(x) = 5^x - 9

Step-by-step explanation:

identify the y-intercept, which is (0, -9)

find the option with: y = mx - 9

                                                 ↑ the y-intercpet

The equation that represents g(x) is [tex]g(x) =5^x - 9[/tex]

The function f(x) is given as:

[tex]f(x) =5^x[/tex]

From the graph, the function f(x) is shifted down by 9 units

The rule of this transformation is represented as:

[tex](x,y) \to (x,y-9)[/tex]

So, we have:

[tex]g(x) =f(x) - 9[/tex]

Substitute [tex]f(x) =5^x[/tex]

[tex]g(x) =5^x - 9[/tex]

Hence, the equation that represents g(x) is [tex]g(x) =5^x - 9[/tex]

Answer:

The answer is a and d

Step-by-step explanation:

The simple interest shows linear growth because it is adding a constant amount.

The compound interest shows exponential growth because it is multiplying by a constant amount.

"Simple interest can be defined as the sum paid back for using the borrowed money, over a fixed period of time."

"Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest."

Here the principle amount is $100.

Simple interest rate is 7%.

Compound interest is 5% compounded quarterly.

After 5 years, with simple interest, the amount will be

= $[100 + (100 × 7 × 5)/100]

= $[100 + 35]

The simple interest shows linear growth because it is adding a constant amount.

After 5 years, with compound interest, the amount will be

= $[100(1 + 0.05/4)⁴⁽⁵⁾]

= $[100(1 + 0.0125)²⁰]

= $[100(1.0125)²⁰]

Therefore, the compound interest shows exponential growth because it is multiplying by a constant amount.

Answer:

  672 m²

Step-by-step explanation:

There are several ways you can do this.

It appears you are intended to divide the isosceles triangle into halves that are right triangles with a leg of 14 and a hypotenuse of 50. The height can then be found from the Pythagorean theorem:

  h² = 50² -14² = 2304

  h = √2304 = 48

Then the area is ...

  A = 1/2bh

  A = (1/2)(28 m)(48 m) = 672 m² . . . triangle area
