What is the distance between the two points at(-3,8) and(-3,-7)
Answers
Answer:
[tex]\boxed {\boxed {\sf 15}}[/tex]
Step-by-step explanation:
Distance is calculated using this formula:
[tex]d=\sqrt {(x_2-x_2)^2+(y_2-y_1)^2[/tex]
where (x₁, y₁) and (x₂, y₂) are the points. We are given (-3,8) and (-3,7). Therefore;
[tex]x_1= -3 \\y_1= 8 \\x_2= -3 \\y_2= -7[/tex]
Substitute the values into the formula.
[tex]d= \sqrt {(-3--3)^2+(-7-8)^2[/tex]
Solve inside the parentheses.
-3 - - 3= -3+3= 0 -7 - 8 = -15[tex]d= \sqrt {(0)^2+(-15)^2[/tex]
Solve the exponents.
0²=0*0= 0 -15²= -15*-15=225[tex]d=\sqrt {0+225[/tex]
[tex]d=\sqrt {225[/tex][tex]d= \pm 15[/tex]
A negative number for distance doesn't make sense, so the distance must be 15.

The variable is "percent of body weight carried in the school backpack." So a child who weighs 60 pounds and carries 9 pounds has a variable value of 15% (9 ÷ 60 = 0.15 = 15%). The American Chiropractic Association (ACA) recommends that children carry no more than 10% of their body weight.PromptWhen we analyze backpack weight as a percentage of body weight, how do 3rd and 5th graders compare?

Follows are the solution to this question:
Step-by-step explanation:
Recommendation from the American Chiropractic Association:
No more than [tex]10\%[/tex] of body weight should be borne through kids
Third classification:
More than [tex]10\%[/tex] of its weight:[tex]11 + 3 +0 +0 = 14[/tex]
ACA Suggestion proportion of children [tex]= ( \frac{14}{21}) \times 100 = 66.67\%[/tex]
Fifth degree:
Over [tex]10\%[/tex] of body weight:[tex]4 + 7 + 1 + 2 + 1 = 15[/tex]
ACA Suggestion for children [tex]= (\frac{15}{22}) \times 100 = 68.18\%[/tex]
ACA suggestion doesn't quite follow either majority for third and fifth grades: fifth grades (68.18%) are marginally hyper-third grades (66.67%).

1) Find f (10).
2) Find x when f (x) = 17
Answers
Answer:
1) 26
2) 7
Step-by-step explanation:
1) f(10)= (3*10)-4 = 26
2) f(x) = 3x-4
=> 17= 3x-4
=> 17+4= 3x
=> 21= 3x
=> x= 21÷3
so, x= 7
State whether the triangles are similar. If so, write a similarity statement and the postulate or theorem you used. The diagram is not drawn to scale.
Answers
Givn : OK = 3, OJ = 30, KN = 1, JM = 3
ON=OK+KN=3+1=4
OM=OJ+JM=30+10=40
In triangles OKJ & ONM,
OKOJ=330=110
ONOM=440=110
Angle O is common in both the triangles.
Two sides are in same proportion and the included angle is common (SAS) . Hence both the triangles are similar.
That means KJNM=110 or the two sides are parallel.
Hence ˆK=ˆN,ˆJ=ˆM corresponding angles.
Two sides in each triangle that are proportional to each other, and a corresponding included angle in both triangles that are congruent, both triangles are similar.
The similarity statement is: [tex]\triangle NOM \sim \triangle KOJ[/tex]Theorem: Side-Angle-Side Similarity Theorem (SAS)Recall:
Two triangles can be proven to be similar by the SAS Similarity Theorem, if they both have two pairs of corresponding side lengths that are proportional to each other and also have a corresponding included angle that is congruent to each other.
Using the image given, let's determine if two of the given side lengths of each triangle are proportional to each other.
Given:
OJ = 30OM = 30 + 10 = 40OK = 3ON = 3 + 1 = 4Thus:[tex]\frac{OM}{OJ} = \frac{ON}{OK}[/tex]
Substitute[tex]\frac{40}{30} = \frac{4}{3}[/tex] (proportional)
Also, <NOM and <KOJ are congruent to each other (included angles).
Therefore, since we have two sides in each triangle that are proportional to each other, and a corresponding included angle in both triangles that are congruent, both triangles are similar.
The similarity statement is: [tex]\triangle NOM \sim \triangle KOJ[/tex]
Theorem: Side-Angle-Side Similarity Theorem (SAS)

One of the legs of a right triangle measures 5 cm and its hypotenuse measures 13 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answers
Answer:
12 cm
Step-by-step explanation:
Use the pythagorean theorem, a² + b² = c², where a and b are legs of the right triangle and c is the hypotenuse.
Plug in the hypotenuse and leg, and solve for b:
a² + b² = c²
5² + b² = 13²
25 + b² = 169
b² = 144
b = 12
So, the other leg is 12 cm.

Question Help In 2005, it took 20.29 currency units to equal the value of 1 currency unit in 1917. In 1990, it took only 13.10 currency units to equal the value of 1 currency unit in 1917 The amount it takes to equal the value of 1 currency unit in 1917 can be estimated by the linear function V given by V(x) = 0.4925x + 13.7485 where x is the number of years since 1990 Thus, V(11) gives the amount it took in 2001 to equal the value of 1 currency unit in 1917. Complete parts (a) and (b) below a) Use this function to predict the amount it will take in 2011 and in 2019 to equal the value of 1 currency unit in 1917
Answers
Answer:
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
Step-by-step explanation:
The value needed to equal the value of 1 currency unit in 1917, in x years after 1990, is given by:
[tex]V(x) = 0.4925x + 13.7485[/tex]
a) Use this function to predict the amount it will take in 2011 and in 2019 to equal the value of 1 currency unit in 1917
2011 is 2011 - 1990 = 21 years after 1990, so we have to find V(21).
[tex]V(21) = 0.4925*21 + 13.7485 = 24.091[/tex]
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
2019 - 1990 = 29, so we also to find V(29).
[tex]V(29) = 0.4925*29 + 13.7485 = 28.031[/tex]
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
Shaneen has $30 to spend on CDs that each cost $10. She wants to calculate n, the number of CDs she can buy with her $30. Which inequality represents the maximum number of CDs she can buy?
Answers
Answer:
[tex]10n \le 30[/tex]
[tex]n \le 3[/tex]
Step-by-step explanation:
Given
[tex]Total = \$30[/tex]
[tex]Cost (each) = \$10[/tex]
Required
Determine the inequality
Assume she wants to buy n CDs.
If 1 CD costs $10, then n CDs costs 10n.
So, the inequality is:
[tex]10n \le 30[/tex]
We used [tex]\le[/tex] because the amount she wants to spend cannot exceed 30
Divide both sides by 10, to solve for n
[tex]n \le 3[/tex]
