hi what is the answerr??
Given:
The rule of input and output function is:
[tex]25-g[/tex]
To find:
The answer if we put 19.
Solution:
Consider the input and output function is:
[tex]f(g)=25-g[/tex]
Substitute [tex]g=19[/tex], we get
[tex]f(19)=25-19[/tex]
[tex]f(19)=6[/tex]
Therefore, the required answer is 6.
Jared bought 7 cans of paint. A can of red paint costs $3.75. A can of black paint costs $2.75. Jared spent $22.25 in all. How many cans of black (b) and how many cans of red (r) did he buy? r+b=7 3.75r+2.75b=22.25 [?] red [ black Enter
Answer:
b = 4
r = 3
Step-by-step explanation:
r + b = 7
solve for 'r' to get r = 7-b
now substitute '7-b' for r in the second equation:
3.75(7-b) + 2.75b = 22.25
26.25 - 3.75b + 2.75b = 22.25
-b = -4
b = 4
r = 3
Jared bought 3 cans of red paint (r = 3) and 4 cans of black paint (b = 4).
To solve this problem, using algebraic equations. Jared recently bought cans of red and black paint, and we want to find out how many cans of each color he purchased. We know that the cost of a red can is $3.75, the cost of a black can is $2.75, and Jared spent a total of $22.25 on the paint. We will set up two equations based on the given information and solve them simultaneously to find the values of "r" (number of red cans) and "b" (number of black cans).
Let's use the following variables:
r : Number of red cans purchased
b : Number of black cans purchased
Now, we can set up two equations based on the information given in the problem:
1. The total number of cans purchased:
Since Jared bought 7 cans in total, we can write this as:
r + b = 7 ... (Equation 1)
2. The total cost of the cans:
The cost of each red can is $3.75, so the total cost of all red cans is 3.75r. The cost of each black can is $2.75, so the total cost of all black cans is 2.75b. Jared spent a total of $22.25, so we can write this as:
3.75r + 2.75b = 22.25 ... (Equation 2)
Now, we have a system of two equations with two variables. We will use the method of substitution or elimination to solve for r and b.
Using substitution, we can rearrange Equation 1 to solve for r:
r = 7 - b
Now, we can substitute this value of r into Equation 2:
3.75(7 - b) + 2.75b = 22.25
Next, distribute and simplify the equation:
26.25 - 3.75b + 2.75b = 22.25
Combine the b terms:
-1b = 22.25 - 26.25
Simplify further:
-1b = -4
Finally, divide both sides by -1 to find the value of b:
b = 4
Now that we have the value of b, we can find r by substituting the value of b into Equation 1:
r + 4 = 7
Subtract 4 from both sides:
r = 7 - 4
r = 3
Therefore, Jared bought 3 cans of red paint (r = 3) and 4 cans of black paint (b = 4).

Given f(x)= 3x+2, what is the Inverse Function?
Answer:
Step-by-step explanation:
For this case we must determine the inverse of the following function:
[tex]f(x)=3x-2[/tex]
Step 1:
We would write
[tex]y=f(x)[/tex] or [tex]y=3x-2[/tex]
Step 2:
We clear x:
[tex]y+2=3x[/tex]
[tex]\frac{y+2}{3}=x[/tex]
Step 3:
"x" and "y" are exchanged:
[tex]y=\frac{x+2}{3}[/tex]
The inverse is:
[tex]f^{-1}(x)=\frac{x+2}{3}[/tex]

Step-by-step explanation:
In an isosceles triangle, angle opposite to equal sides are equal.
So according to angle sum property :
x + x + 56 = 180
2x + 56 = 180
x = 180 - 56 /2

There is sufficient evidence to reject the null hypothesis at the 0.05 level since the test statistic is greater than the p-value. Answer A: There is sufficient evidence to reject the null hypothesis at the 0.05 level since the test statistic is greater than the p -value. A
Answer:
The null hypothesis must be rejected
Step-by-step explanation:
Here the P value is less than 0.05
which means that the test results are statistically significant and there are sufficient evidence to reject the null hypothesis and accept the alternative hypothesis.
Hence, the null hypothesis must be rejected.

In a lab experiment, 610 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 23 hours. How long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present?
Answer:
It would take 19 hours and 36 minutes until there are 1040 bacteria present.
Step-by-step explanation:
Given that in a lab experiment, 610 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 23 hours, to determine how long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present, the following calculation must be performed:
610X = 1040
X = 1040/610
X = 1.7049
2 = 23
1.7049 = X
1.7049 x 23/2 = X
39.2131 / 2 = X
19.6 = X
100 = 60
60 = X
60 x 60/100 = X
36 = X
Therefore, it would take 19 hours and 36 minutes until there are 1040 bacteria present.

log(x)²=(logx)², find the value of x
Answer:
x = 7.39
Step-by-step explanation:
log(x)²=(logx)², find the value of x
log x² = log x * log x
2log x = log x * log x
2 = log x
Take the exponent pf both sides
e² = e^logx
e² = x
x = e²
x = 7.39

Answer:
The dimensions of the rectangle are:
2a^2b^2 and 3ab^2 + 5a + 7b
Step-by-step explanation:
The question is asking for the length and width of the rectangle, and gives you an equation that shows the area of the rectangle. It says to factor out the GCF to find these dimensions. In simpler terms, the question wants you to divide the equation for the area, 6^3b^4 + 14a^2b^3 + 10a^3b^2, into two different equations for the length and width, which can't be divided more.
We have three terms to find the greatest common factor (GCF) of. 6^3b^4, 14a^2b^3, and 10a^3b^2. First, let's factor out the 2. This leaves us with
2(3^3b^4 + 7a^2b^3 + 5a^3b^2)
It seems like we're done with factoring out coefficients, for 3, 5, and 7 are all prime. Now, variables. Each term has a factor of a^2b^2. (not more, for this is the limit of 14a^2b^2.)
2a^2b^2(3ab^2 + 7b + 5a) . (this is the same as the answer above, but I changed the order of 7b and 5a there because some online things are specific and don't like it if you don't put the equations in order.)
And that's it!
