Answer:
The correct solution is "[tex]10g^3+2g^2+17g-14[/tex]".
Step-by-step explanation:
The given expression is:
= [tex](10g^3-8g^2+5g-14)+(10g^2+12g)[/tex]
By opening the brackets, we get
= [tex]10g^3-8g^2+5g-14+10g^2+12g[/tex]
By applying addition and subtraction, we get
= [tex]10g^3+2g^2+17g-14[/tex]

Marcus measured the height, In Inches, y, of plants over the course of 3 weeks, The correlation coefficient between the number of days, x, and the height of the plants is 0.85. Which could be concluded based on the correlation coefficient of the data?
A. There is a strong relationship showing that as the number of days increases, the height of the plants increases.
B. There is a strong relationship showing that as the number of days Increases, the height of the plants decreases.
С. There is a weak relationship showing that as the number of days increases, the height of the plants increases,
D. There is a weak relationship showing that as the number of days increases, the height of the plants decreases,
Answer:
A) There is a strong relationship showing that as the number of days increases, the height of the plants increases.
Step-by-step explanation:
Because the correlation coefficient of 0.85 is very close to 1, there's going to be a strong, positive linear correlation between the two variables. Therefore, option A is correct.
There is a strong relationship showing that as the number of days increases, the height of the plants increases.
What is the correlation coefficient of the data?A correlation coefficient is a bivariate statistic when it summarizes the relationship between two variables, and it’s a multivariate statistic when you have more than two variables.
Marcus measured the height, In Inches, y, of plants over the course of 3 weeks, The correlation coefficient between the number of days, x, and the height of the plants is 0.85.
When the correlation coefficient is above 0.8, the correlation cofficeint is strong.
And the function is increasing.
So, there is a strong relationship showing that as the number of days increases, the height of the plants increases.
Hence, there is a strong relationship showing that as the number of days increases, the height of the plants increases.

Which side lengths form a right triangle?
Choose all answers that apply:
А
9, 12, 15
B
2,6,738
3,9, 91
Answer:
Here is your answer :
For option ( a )
We know that the longest side of any triangle is its hypotenuse.
So, hypotenuse = 15
Other sides = 9, 12
By Pythagoras Theroem ,
Hypotenuse^2 = Sum of Square of other sides
( 15 )^2 = ( 9 )^2 + ( 12 )^2
225 = 81 + 144
225 = 225
Hence,it can be sides of a right angled triangle.
For option ( b ),
We know that the hypotenuse of a right angled triangle is its longest side.
So, Hypotenuse = √38 = 6√2
Other sides = 2 , 6
By Pythagoras Theroem ,
Hypotenuse^2 = Sum of squares of other sides
( 6√2 )^2 = ( 6 )^2 + ( 2 )^2
72 = 36 + 4
72 ≠ 40
So, it can't be sides of a right angled triangle.
For option ( c )
We know the longest side of any right angled triangle is its hypotenuse.
So, Hypotenuse = √91
Other sides = 3 , 9
By Pythagoras Theroem ,
Hypotenuse^2 = Sum of squares of other sides
( √91 )^2 = ( 3 )^2 + ( 9 )^2
91 = 27 +81
91 ≠ 108
So, it can't be sides of a right angled triangle.

The final answer is option ( a ).

(Please help ASAP 16 points! Thanks in advance!) solve -2a - 5 > 3
Answer:
a<-4
Step-by-step explanation:
To solve this, you have to isolate a. This means you will have to add 5 to both sides. This will make the equation -2a>8. Divide both sides by 2 to get -a>4. Divide each side by -1 to get a>-4. Because you have to flip the sign when you divide by a negative number, you have to change it into a<-4.

Gerardo says that a cube with edges that measure 10 centimeters has a volume that is twice as much as a cube with sides that measure 5 centimeters. Complete the explanation and correction for Gerardo's error. A cube with sides of 5 cm holds 5 layers of 25 cm cubes, which is cu cm. A cube with sides of 10 cm could hold 10 layers of 100 cm cubes, which is cu cm. Although 10 is twice as much as 5, a cube has ? , so each dimension is ? as great.
Answer:
A cube with sides of 5 cm holds 5 layers of 25 cm cubes.
A cube with sides of 10 cm could hold 10 layers of 100 cm cubes.
Step-by-step explanation:
For Cube a
Edge length = 10cm
Hence,
Volume = (side length)³
Volume = (10cm)³
= 1000cm³
For cube b
Side/Edge length = 5cm
Volume of cube = (5 cm)³
= 125 cm³
Gerardo statement is wrong.
Therefore, the correct explanation is given as:
A cube with sides of 5 cm holds 5 layers of 25 cm cubes.
A cube with sides of 10 cm could hold 10 layers of 100 cm cubes.
Two figures are similar with a scale factor of 5/2.
a. What is the ratio of corresponding lengths?
b. What is the ratio of their perimeters?
c. What is the ratio of their areas?
d. What is the ratio of their volumes?
e. What is the ratio of corresponding angle measures?
Answer:
If we have two figures, F and F'
Such that if we start with F, and dilate it with a scale factor K, we get F'.
We will have:
All the measures of F', are K times the correspondent measures of F.
Then if F has s₁, s₂, ..., sₙ sides, the sides of F' will be:
K*s₁, K*s₂, ..., K*sₙ
The ratio between correspondent sides will be equal to K
The ratio between perimeters will also be equal to K (because the perimeter is the sum of all the sides of each figure, so we can just take K as a common factor)
In the case of the area, because we usually multiply a measure by another, a factor K^2 will appear, and the quotient between the areas is K^2
And finally, for the volumes, the ratio will be K^3
a) The ratio of corresponding lengths is K, in this case is 5/2
b) The ratio of the perimeters is K, in this case is 5/2
c) The ratio of the areas is K^2, in this case is (5/2)^2 = 25/4
d) The ratio of the areas is K^3, in this case is (5/2)^3 = 125/8
e) Two figures are similar if the figures have the same shape, then the corresponding angles are exactly the same, then the ratio of corresponding angle measures is 1.
