(-1-7f)to the power of 2
please explain
Answer:
The product to this problem is simplified to: [tex]1+14f+49f^{2}[/tex]
Step-by-step explanation:
1) First place out what was given:
[tex](-1 -7f)^{2}[/tex]
Squared is the same thing as multiply to itself, so you would create a pair of
[tex](-1 -7f)^{2}[/tex]
(For example, if you said: [tex]x^{2}[/tex] it is the same as saying or putting: x · x)
2) Then create your pair which would look like:
[tex](-1 -7f)(-1 -7f)[/tex]
3) Next step is to do the FOIL method
(The FOIL method is where you do First, Outside, Inside, an Last)(Like how it is shown in the picture, we will do this method and create one whole expression!)
4) Creating and combining your expression into one whole problem, by using the foil method.
[tex](-1 -7f)(-1 -7f)[/tex]
First - F: [tex]1[/tex]
Outside - O: [tex]7f[/tex]
Inside - I: [tex]7f[/tex]
Last: [tex]49f^{2}[/tex]
This will be:
[tex]1+14f+49f^{2}[/tex]
And this will be your answer!

Answer:
let's see what to do buddy...
Step-by-step explanation:
" First four terms " means :
t(1) , t(2) , t(3) , t(4)
[tex]t(1) = a(1) = 5(1) - 1 = 5 - 1 = 4 \\ t(2) = a(2) = 5(2) - 1 = 10 - 1 = 9 \\ t(3) = a(3) = 5(3) - 1 = 15 - 1 = 14 \\ t(4) = a(4) = 5(4) - 1 = 20 - 1 = 19 \\ \\ t(1) = 4 \\ t(2) = 9 \\ t(3) = 14 \\ t(4) = 19[/tex]
So the first four terms

She decides to buy 40 bouquets for $120 because she thinks that price is a better value than 40 bouquets for $2.50 each.
Explain Kendra’s error
Answer:
She messed up because if a bouquet costs $2.50 then 2.50 times 40 is $100 so she could have saved 20 more dollars
Answer:
Sample Response: To find the unit cost for her choice, divide $120 by 40 to get $3.00 per bouquet. This unit cost is more than the other deal.

f(x) = 2[[X-3.5]] : What is f(2)?
Answer:
f(2)= -3
Step-by-step explanation:
f(x)= 2 [x-3.5]
f(2)= 2[2-3.5] substitute all of your "x" for the number "2" f(2)=2[ -1.5] 2-3 is -1.5
f(2)= -3 2 times -1.5 is -3
The value of f(2)= -3
Calculation of the value of f(2):Since f(x) = 2[[X-3.5]
So,,
f(x)= 2 [x-3.5]
f(2)= 2[2-3.5]
f(2)=2[ -1.5]

There are 130 people in a sport centre. 65 people use the gym. 51 people use the swimming pool. 44 people use the track. 15 people use the gym and the pool. 14 people use the pool and the track. 10 people use the gym and the track. 1 person uses all three facilities. A person is selected at random. What is the probability that this person uses at least 2 facilities?
Answer:
0.285
Step-by-step explanation:
Total peoples are, n=130
Number of people who use gym =65
Number of people who use swimming pool =51
Number of people who use the track =44
Number of people who use the gym and the pool =15
Number of people who use the pool and the track =14
Number of people who use the gym and the track =10
Number of people who use the gym, the pool, and the track =1
So, the number of people who use the gym and the pool =15-1=14
The number of people who use the pool and the track =14-1=13
The number of people who use the gym and the track =10-1=9
Now, the people who use at least two facilities are the people who use 2 or 3 facilities, which is 14+13+9+1=37.
So, the number of favorable outcomes =37
Total number of sample space, n=130
Hence, the probability, P, that the 1 randomly selected person uses at least 2 facilities is as follows:
[tex]P=\frac{37}{130}=0.285[/tex]

Tres amigos quieren rentar una cuatrimoto la cual cuesta $400 por una hora cada uno pone las siguientes cantidades Adriana 50 Luis 160 y Ramiro el resto cuánto tiempo debe subirse cada quien de acuerdo a las recupero con operaciones por favor y una explicación
Answer:
Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.
Step-by-step explanation:
Asumamos en primer lugar que los tres amigos rentan la cuatrimoto durante una hora, entonces cada persona utiliza la cuatrimoto en proporción al dinero. A continuación, obtenemos el tiempo estimado por cada usuario a partir de una regla de tres simple:
[tex]\Delta t = \frac{c_{a}}{c_{r}}\cdot (60\,min)[/tex]
Donde:
[tex]\Delta t[/tex] - Tiempo de uso de la cuatrimoto, medido en minutos.
[tex]c_{a}[/tex] - Dinero aportado por el usuario, medido en pesos.
[tex]c_{r}[/tex] - Coste de renta de la cuatrimoto, medido en pesos.
Entonces calculamos el tiempo correspondiente a cada amigo:
Adriana ([tex]c_{a} = \$\,50[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,50}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 7.5\,min[/tex]
Luis ([tex]c_{a} = \$\,160[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,160}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 24\,min[/tex]
Ramiro ([tex]c_{a} = \$\,190[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,190}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 28.5\,min[/tex]
Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.
which ratio is greater than 11/16
Answer:
3:4
Step-by-step explanation:
because in a simplified ratio, it tells us that in any set of whatever number (total of 3 and 4), there will be a quantity in simplification of 3 on one side.
3:4 is also a simplified ratio which can be reversed to a higher fraction than 11/16 (which would be 11:16 in ratio form fue to the inability to simplify) therefore making it a greater ratio.Solve.

Beth is designing a business card. She makes a scale drawing of her old business card by using a scale factor of Five-fourths. Her scale drawing is a 2 and one-half-inch by 5-inch rectangle. The print shop says that the scale drawing is a reduction of the original card because the original card must be 3 and StartFraction 1 over 8 EndFraction inches by 6 and one-fourth inches. Which explains the print shop's error and gives the correct dimensions of Beth's original card?
Answer:
The width and length of the old card are 2 inches and 4 inches respectively.
Step-by-step explanation:
The given scale factor, [tex]C=\frac{5}{4}[/tex]
She draws is a rectangle by using the scale factor of C.
The width of her drawing, [tex]b=2\frac{1}{2}[/tex] [tex]=\frac{5}{2}[/tex] inch, and
the length of the drawing, [tex]a=5[/tex] inch.
Let [tex]a'[/tex] and [tex]b'[/tex] be the length and width of her reference business card (the old one as mentioned).
[tex]\text{Scale factor}=\frac{\text{New dimension}}{\text{Reference dimention}}[/tex]
Here, the dimension is the length of the sides of rectangular cards.
So, [tex]C=\frac{a}{a'}[/tex] and [tex]C=\frac{b}{b'}[/tex]
[tex]\Rightarrow \frac{5}{4}=\frac{5}{a'}[/tex]
[tex]\Rightarrow a'=4[/tex] inch
and [tex]\frac{5}{4}=\frac{5/2}{b'}[/tex]
[tex]\Rightarrow b'=2[/tex] inch
So, the old business card is of the dimensions 2 inches by 4 inches, which are the correct dimensions.
Actually, the print shop multiplied he scale-factor, C, with the new scaled length to get the reference length (lengths of original old card), which was the error. In, fact, as already described earlier, the new dimensions can be obtained by multiplying the scale-factor, C, with the reference dimensions.
Answer:
C. The scale factor is a fraction so the scale drawing is a reduction, and the original card is 2 inches by 4 inches.

Answer:
Step-by-step explanation:
Given the expression [tex]\frac{720,800}{x} = 7.208[/tex], we are to find the value of with powers of 10.
From the equation:
[tex]\frac{720,800}{x} = 7.208[/tex]
cross multiply
[tex]720,800 = 7.208x\\7.208x = 720,800[/tex]
divide both sides by 7.208
[tex]\frac{7.208x}{7.208} = \frac{720,800}{7.208} \\x = 100,000[/tex]
express x in powers of 10
[tex]x = 10 * 10 * 10 * 10* 10\\x = 10^5[/tex]
Similarly given the equation [tex]\frac{720,800}{y} = 72.08[/tex]
From the equation:
[tex]\frac{720,800}{x} = 72.08[/tex]
cross multiply
[tex]720,800 = 72.08x\\72.08x = 720,800[/tex]
divide both sides by 7.208
[tex]\frac{72.08x}{72.08} = \frac{720,800}{72.08} \\x = 10,000[/tex]
express x in powers of 10
[tex]x = 10 * 10 * 10 * 10\\x = 10^4[/tex]
For the equation [tex]\frac{720,800}{z} = 720.8[/tex]
From the equation:
[tex]\frac{720,800}{z} = 720.8[/tex]
cross multiply
[tex]720,800 = 720.8z\\720.8z = 720,800[/tex]
divide both sides by 7.208
[tex]\frac{72.08z}{720.8} = \frac{720,800}{720.8} \\z = 1,000[/tex]
express x in powers of 10
[tex]z = 10 * 10 * 10\\z = 10^3[/tex]
The dividing 720,800 by 101010 successively four times in the parentheses results in 720.8
To complete the equations using powers of 101010:
720,800 ÷ (720,800 ÷ 720,800) = 7.208 = 7.208 equals 7.208
Explanation: Dividing 720,800 by 720,800, and then dividing the result by 720,800, yields 7.208.
720,800 ÷ (720,800 ÷ (720,800 ÷ 101010)) = 72.08 = 72.08 equals 72.08
Explanation: Dividing 720,800 by 101010, and then dividing 720,800 by the result, and finally dividing 720,800 by the new result, gives us 72.08.
720,800 ÷ (720,800 ÷ (720,800 ÷ (720,800 ÷ 101010))) = 720.8 = 720.8 equals 720.8
