The grocery store sells kumquats for $3.75 a pound and Asian pears for $2.25 a pound. Write an equation in standard form for the weights of kumquats k and Asian pears p that a customer could buy with $14.


Answer:

an equation in standard form is 3.75k+2.25p=14

Step-by-step explanation:

The Standard form of an equation is written as:

Ax+By = C

here, k represents he weights of kumquats and p represents the weight of  Asian pears .

As per the statement:

The grocery store sells kumquats for $3.75 a pound

3.75k

and Asian pears for $2.25 a pound.

2.25p

We have to find the an equation in standard form

A customer could buy kumquats and Asian pears with $ 14

then;

3.75k+2.25p=14

Therefore, an equation in standard form is 3.75k+2.25p=14

Suppose you are able to manipulate a plants access to components in the photosynthesis equation. drag each label to the appropriate bin to predict how that action will affect plant growth. for each increase or decrease, assume that every other component of the photosynthesis equation is unlimited.


We know that the word equation for the reaction taking place during photosynthesis is:

carbon dioxide + water + sunlight → glucose + oxygen

Therefore, the more the reactants are provided, the more the plant will grow. The lesser the reactants, the lesser the growth. Providing products will not alter the rate of photosynthesis. The factors may be grouped as:

Increase plant growth:
-increase sunlight
-increase carbon dioxide
-increase water

No effect on plant growth:
-increase glucose
-increase oxygen
-decrease glucose
-decrease oxygen

Decrease plant growth:
-decrease water
-decrease sunlight
-decrease carbon dioxide

If x=6 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the equation?


Answered by answersmine AT 22/10/2019 – 02:31 AM

If x=6 is the only intercept, it means that the quadratic is tangential to the x-axis, or equivalently x=6 is a root with multiplicity 2.
The discriminant is typically zero for multiplicity 2 in a quadratic. 
It will be clear looking at the quadratic formula:
if D=b^2-4ac = discriminant of the quadratic, then
x1=(-b+sqrt(D))/2a or x2=(-b-sqrt(D))/2a
if x1=x2 (double root, or multiplicity 2) then clearly D has to be zero.

Bill bought a new cellular phone. His monthly bill will be $34.99 each month which includes 100 minutes of use. Additional minutes will cost $0.23 per minute. Write an equation that represents the cost of the bill C in terms of m, which is the number of minutes used ABOVE the 100 that are included in the base price. a. C = 34.99(m – 100) + 0.23 c. C = 0.23m b. C = 0.23m + 34.99 d. C = 0.23(m – 100) + 34.99


Answer:

d. C = 0.23(m – 100) + 34.99

Step-by-step explanation:

Let C = X + Y, where

C = Cost of the bill in terms of m

X = First term of the equation

Y = Second term of the equation

X = add additional minutes to $ 0.23 minus the 100 minutes of use allocated.

X = 0.23 (m – 100)

Y = Base price monthly will be $ 34.99

Y = 34.99

C = X + Y

C = 0.23 (m – 100) + 34.99

Note: The only possible answer is 0.23 (m – 100) + 34.99, but we must assume that “m” is greater than or equal to 100, that is, Bill consumes at least his 100 minutes assigned by the base price.

Hope this helps!

Given the exponential equation 2x = 128, what is the logarithmic form of the equation in base 10?


Answer:

log_{2}128= frac{log_{10} 128}{log_{10} 2}.  

Step-by-step explanation:

Given : 2^{x} = 128.

To find :  what is the logarithmic form of the equation in base 10

Solution : We have given that 2^{x} = 128.

By th change base rule ( inverse of exponential function )

a^{b} = c is equal to  log_{a}(c) = b

Then 2^{x} = 128 in to logarithm form  log_{2}(128) = x.

Then in to the base 10 logarithmic form.

By the change of base formula log_{b}a= frac{log_{10} a}{log_{10} b}.

Then , log_{2}128= frac{log_{10} 128}{log_{10} 2}.  

Therefore, log_{2}128= frac{log_{10} 128}{log_{10} 2}.

E. solid copper sulfide and silver nitrate react to form copper (ii) nitrate and solid silver sulfide. write a balanced chemical equation that describes the reaction. identify the oxidation number of each element in the reaction. (you do not need to include the total contribution of charge.) is this reaction a redox reaction or a non-redox reaction? explain your answer.


Answer:

The given reaction is not a redox reaction.

Explanation:

Redox reaction is defined as chemical reaction in oxidation and reduction reactions occurs simultaneously.

Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases.

Reduction reaction is defined as the reaction in which an atom gains electrons. Here, oxidation state of the atom decreases.

Solid copper sulfide when immersed in silver nitrate solution it reacts to form silver sulfide precipitate and copper(II) nitrate solution.

CuS(s)+2AgNO_3(aq)rightarrow Cu(NO_3)_2(aq)+Ag_2S(s)

Oxidation states of elements on reactant side:

Oxidation state of copper  = +2

Oxidation state of sulfur = -2

Oxidation number of silver  +1

Oxidation number of nitrogen = +5

Oxidation number of oxygen = -2

Oxidation states of elements on product side:

Oxidation state of copper  = +2

Oxidation state of sulfur = -2

Oxidation number of silver  +1

Oxidation number of nitrogen = +5

Oxidation number of oxygen = -2

No change in oxidation states of elements is observed which means that the given reaction is not a redox reaction.

Please help meee!!!! A circle has its center at (1, 4) and a radius of 2 units. What is the equation of the circle? (x − 1)2 + (y − 4)2 = 4 (x + 2)2 + (y + 4)2 = 2 (x + 1)2 + (y − 4)2 = 4 (x − 1)2 + (y − 4)2 = 2


Answer:

A. (x-1)^2+(y-4)^2=4

Step-by-step explanation:

We have been given that a circle has its center at (1, 4) and a radius of 2 units. We are asked to write the equation of the given circle.

Since we know that the center-radius form of circle equation is:

(x-h)^2+(y-k)^2=r^2, where (h,k) is the center of circle and r is radius of circle.

Upon substituting our given values in above format we will get,

(x-1)^2+(y-4)^2=2^2

(x-1)^2+(y-4)^2=4

Therefore, the equation of our given circle is (x-1)^2+(y-4)^2=4 and option A is the correct choice.

When a solution of LiC2H3O2 reacts with a solution of MgSO4, what is the net ionic equation? No reaction Mg+2 (aq) + C2H3O2- (aq) → Mg(C2H3O2)2 (s) Mg+2 (aq) + 2C2H3O2- (aq) → Mg(C2H3O2)2 (s) 2Li+ (aq) + SO4-2 (aq) → Li2SO4 (s)


Answered by answersmine AT 22/10/2019 – 02:56 AM

I think the correct answer would be the first option. When a solution of LiC2H3O2 is mixed  with a solution of MgSO4, no reaction would be observed from the mixture. This is because magnesium cannot replace lithium from the acetate compound. Lithium is the least reactive substance based from the activity series. So, it can only react with a few substances and it does involve the reaction with magnesium sulfate. It is the very least reactive of all the alkali metals.

Identify both the x- and y-intercepts of the linear equation graphed on the coordinate plane above. Use the intercepts to write an equation of the line in point-slope form, slope-intercept form, and general form of a linear equation.Complete your work in the space provided or upload a file that can display math symbols if your work requires it. In your work, be sure to include the coordinates for both intercepts and the equations of the line in all three formats.


The x int (where the line crosses the x axis) is (-2,0)
the y int (where the line crosses the y axis) is (0,-2)

(-2,0)(0,-2)
slope = (-2 – 0) / (0 – (-2) = -2/2 = -1

y = mx + b
slope(m) = -1
use either of ur points (-2,0)…x = -2 and y = 0
sub and find b
0 = -1(-2) + b
0 = 2 + b
-2 = b

so ur equation in slope intercept form is : y = -x – 2

y = -x – 2
x + y = -2
x + y + 2 = 0 <== general form

there can be 2 answer for point slope form…
y – y1 = m(x – x1)
slope(m) = -1
(-2,0)…x1 = -2 and y1 = 0
sub
y – 0 = – (x – (-2)
y – 0 = -(x + 2) <=== point slope form

y – y1 = m(x – x1)
slope(m) = -1
(0,-2)…x1 = 0 and y1 = -2
sub
y – (-2) = – (x – 0)
y + 2 = – (x – 0) <== point slope form
