what’s the square root of 5 times the square root of 5
Answer:
5
Step-by-step explanation:
Looked it up on google
Answer:
[tex] \sqrt{5} \times \sqrt{5} = 5[/tex]
Step-by-step explanation:
bc 5 isn't a perfect square I'll use another number as an example.
the square root of 36 is 6 right? so 6 × 6 is 36.
or it can be written as 6^2=36.
hope this makes sense

Answer:
5
Step-by-step explanation:
C(-6,5) D (-3,1)
to find a distance between two points use the following formula:
d=√(x2-x1)²+(y2-y1)²
d=√-3-(-6)+(1-5)²
d=√(-3+6)²+(-4)²
d=√(3)²+16
d=√25
d=5
Answer:
7
Step-by-step explanation:
you had to go up 3 times on the x place to make -6 to -3
you had to go down 4 times to make 5 go to 1
so 3+4 is 7

yeah....
What is equivalent to 3x-4y=6
Answer:
y= (3/4) x - (3/2)
Step-by-step explanation:
3x - 4y = 6 (using algebra add the 4y to the other side & subtract the 6 to the other side >> 3x - 6 = 4y (then divide everything by 4 to get y by itself) >> 3/4x - 6/4 = y (then simplify) >> 3/4x - 3/2 = y
Find the domain of the function. (Enter your answer using interval notation.)
Answer:
[tex](-\infty,-9)\cup(-9,\infty)[/tex]
Step-by-step explanation:
The domain of a rational function is all real numbers except for when the denominator equals 0.
So, to find the domain restrictions, set the denominator to 0 and solve for x.
We have the rational function:
[tex]s(y)=\frac{7y}{y+9}[/tex]
Set the denominator to 0:
[tex]y+9=0[/tex]
Subtract 9:
[tex]y\neq-9[/tex]
So, the domain is all real numbers except for -9.
In other words, our domain is all values to the left of negative 9 and to the right of negative 9.
In interval notation, this is:
[tex](-\infty,-9)\cup(-9,\infty)[/tex]
And we're done :)
What’s the value of |4|
Answer:
The value is 4
Step-by-step explanation:
This is because the value of an absolute number is always positive so the absolute value of 4 would remain 4.
Answer: 4
Step-by-step explanation: The absolute value is how far a number is away from 0
The table shows the distance y (in miles) that you travel on a road in x minutes. What type of function best models the data?
Time (minutes), x Distance (miles), y
0 0
20 15
40 30
60 45
80 60
constant function
linear function
absolute value function
quadratic function
Answer:
Linear Function
Step-by-step explanation:
Given
The table showing values of x and y
Required
Determine the type of function
To determine the type of function, the table represents;
One will need to determine the table equation.
Start by solving for the slope;
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
When x - 0; y = 0 and When x = 80; y = 60.
This gives
[tex]m = \frac{0 - 60}{0 - 80}[/tex]
[tex]m = \frac{- 60}{- 80}[/tex]
[tex]m = \frac{3}{4}[/tex]
The formula is determine as follows;
[tex]y - y_1 = m(x - x_1)[/tex]
When x - 0; y = 0; m = 3/4; This gives
[tex]y - 0 = \frac{3}{4}(x - 0)[/tex]
[tex]y = \frac{3}{4}(x - 0)[/tex]
Open Bracket
[tex]y = \frac{3}{4}x - 0[/tex]
[tex]y = \frac{3}{4}x[/tex]
The above is an example of a linear equation.
Hence; option B answers the question

f(x) = 3x + 10
Of(x) = 2x + 3
f(x) = 4x + 5
O f(x) = 3x - 10
Answer:
f(x) = 2x +3
Step-by-step explanation:
If we assume the first point in your table is supposed to be (-7, -11), then the function exhibits a constant slope of 2.
For example, from (x, y) = (3, 9) to (4, 11) the x-value changes by 1, but the y-value changes by 2.
The only offered answer choice with a slope (x-coefficient) of 2 is ...
f(x) = 2x +3
The value of y is directly proportional to
the value of x. If y = 84 when x = 16, what
is the value of y when x = 75?
Answer:
y = 393.75
Step-by-step explanation:
Proportions:
84 ⇔ 16
y ⇔ 75
y = 75*84/16
y = 393.75
What is the slope of the line passing through the point (2,-1) and the origin?
Answer:
y = - 1/2x
Step-by-step explanation:
A) 5y +32=72
B) K/2+24=29
Step-by-step explanation:
A)y=8
B)k=10
5y=72-32
5y=40
y=8
1/2k+24=29
k+48=58
k=58-48
k=10
12. A road race is 15 kilometers long. After the starting line, there are water stations every
0.3 kilometer. How many water stations are there?
Answer:
50
Step-by-step explanation:
Given
there is 1 water station at every 0.3 KM
If there are n water stations at every 0.3 KM
then KM covered by them = n*0.3 = 0.3n
given that total KM covered is 15 km
Thus,
0.3n = 15
=> n = 15/0.3 = 50
Thus, there are 50 water stations.

During the third week of practice Ellison's cross country team ran 6 miles less than triple the number of miles they ran the
first week. If they ran m miles in practice the first week, write an expression that represents the number of miles that
the cross country team ran during the third week.
a
3-6m
3m-6
b
C
6-3m
Od
6m-3
Answer:
first week = m miles
second week = 6 miles less than triple the number of miles they ran the
first week.
Triple of the number of miles they ran the first week = 3 * m = 3m
Therefore = 3m - 6
Rewrite the function by completing the square.
f(x) = x² - 9x + 14
F(x)=?(x+?)^2+?
Answer:
(x-9/2)²-25/4
Step-by-step explanation:
x² - 9x + 14
to complete the square , need to add a term (b/2)²: (-9/2)²=81/4
x² - 9x -81/4+ 14+81/4
x²-9x+81/4=(x-9/2)²
14-81/4=66-81/4=-25/4
(x-9/2)²-25/4

Step-by-step explanation:
Answer:
6 m and 18 m
Step-by-step explanation:
There are 2 similar triangles in the diagram
lamppost/ lamppost's shadow/ line from end of shadow to top of lamppost
Nick/ Nick's shadow/ line from end of shadow to top of Nick
Therefore the ratios of corresponding sides are equal.
Note the shadow of the lamppost = 12 + x, thus
[tex]\frac{6}{2}[/tex] = [tex]\frac{12+x}{x}[/tex] ( cross- multiply )
6x = 2(12 + x) = 24 + 2x ( subtract2x from both sides )
4x = 24 ( divide both sides by 4 )
x = 6
Thus
Nick's shadow is 6 m long
Lamppost's shadow is 12 + 6 = 18 m long

The pizza has an area of 78.5 in². What is the minimum width of a placemat that can be placed underneath it so that the pizza does not touch the table? Use 3.14 for pi.
Answer:
10 inStep-by-step explanation:
This problem bothers on the mensuration of flat shapes, circles and square.
we know that the pizza has a circular profile
and the place-mat has a square profile.
Step one:
let us solve for the radius of the pizza
[tex]area-of- pizzza= \pi r^2\\\\ 78.5= 3.142*r^2\\\\r^2= 78.5/3.142\\\\r^2= 24.98\\\\r= \sqrt{24.98} \\\\r=4.998\\\\r= 5 in[/tex]
Step two:
from inspection we know that the width of the place-mat is same as the diameter of the pizza
hence diameter of pizza
= 2r
=2*5
=10 in
A medical researcher measures the increase in heart rate of patients under a stress test. What kind of variable is the researcher studying?
The options in this question are not given; here is the complete question:
A medical researcher measures the increase in heart rate of patients under a stress test. What kind of variable is the researcher studying?
A. Identifier
B. Categorical
C. Quantitative
D. Qualitative
The answer to this question is C. Quantitative
Explanation:
In research, a quantitative variable refers to a variable or factor that involves using numbers, percentages, and in general, quantities to be understood. Moreover, this is the opposite of qualitative variables that involve using qualities. The medical research described includes a quantitative variable because heart rate can only be measured and understood through numbers. Also, other types of variables such as qualitative or categorical are not involved because these are related to qualities rather than numbers.
there are 300 window for b buildings. assuming there is an equal number of windows per building, how many windows does each building have
Answer:
[tex]300\div b[/tex] windows
Step-by-step explanation:
We can find how many windows each building has by changing our old expression.
If we assume [tex]b[/tex] is the amount of buildings and [tex]w[/tex] is the amount of windows per building, we can make the equation:
[tex]wb = 300[/tex].
Now we want to isolate w on one side.
To do this we can divide both sides by b.
[tex]wb\div b = 300\div b\\\\w = 300\div b[/tex]
So the amount of windows per building is [tex]300 \div b[/tex].
Hope this helped!

if y varies directly with x and y = -12 when x = 6 find x when y = -4 A -2 B 3 C -3 D 2
Answer:
D
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 12 when x = 6, thus
- 12 = 6k ( divide both sides by 6 )
- 2 = k
y = - 2x ← equation of variation
When y = - 4, then
- 4 = - 2x ( divide both sides by - 2 )
2 = x → D
