Answer:
f(-4) = 72, f(x + 5) = 3x² + 23x + 36
Step-by-step explanation:
f(-4) = 3(-4)² - 7(-4) - 4
= 48 - (-28) - 4
f(-4) = 72
f(x + 5) = 3(x + 5)² - 7(x + 5) - 4
= 3(x + 5)(x + 5) - 7(x + 5) - 4
= 3(x² + 10x + 25) - 7(x + 5) - 4
= 3x² + 30x + 75 - 7x - 35 - 4
f(x + 5) = 3x² + 23x + 36

To rent an instrument from the school it costs a $50 insurance fee and then $350 per day of use. If Sally rents her instrument for 25 days before she buys her own, how much did she have to pay to rent one?
Answer:
$2,500
Step-by-step explanation:
$350 per day for 25 days
350*25=2450
Add the 50 for insurance and that makes it 2500
If its wrong im sorry
Answer:
8800 is the amount before she buys her own instrument
Step-by-step explanation:
350 x 25 = 8750
8750 + 50 = 8800

Answer:
x=55°, y=35°, z=145°
Step-by-step explanation:
y is vertically opposite to 35, meaning they share the same value.
We can see that x and y add to 90, as together they take up the space as the angle with the box (a symbol for 90°). This means x+y=90, and x=90-y, which can be written as x=90-35 when subbing y with its known value. This solves to x=55.
z and 35 together form a straight line, meaning z+35=180, or z=180-35. This can be solved to z=145.
**This content involves working out values of angles, which you may wish to revise. I'm always happy to help!
Answer:
(x,y,z) = (55,35,145)
Step-by-step explanation:
the angle of a straight line is 180 degrees. We can see that we have a right angle (90 degrees) and 35 degrees. So x must be 180-35-90=55
since the line on the the left if perpandicular with the line going up x and y must add to form a right angle (90 degrees). therefore y = 90-x=35.
finally, z is in a similar situation to x where the angle of the line is 180. We know y so z = 180-y =145

Find the area of each figure. (Or as much as u can)
9514 1404 393
Answer:
7. 91 m²
8. 56 in²
9. 105 in²
10. 135 m²
Step-by-step explanation:
The formula for the area of a triangle is ...
A = 1/2bh
where b is the base length, and h is the height perpendicular to the base.
The formula for the area of a trapezoid is ...
A= 1/2(b1 +b2)h
where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them. Note that this formula is virtually identical to the triangle formula, with the triangle 'b' being replaced by (b1+b2).
__
Fill in the numbers and do the arithmetic. The result is shown in the attachment. (We have used the triangle formula for all, with b1+b2 being used for 'b' to find the area of the trapezoids.)
7. A = 1/2(14 m)(13 m) = 91 m²

Answer:
7. [tex]BC=22[/tex]
8. [tex]EF=8[/tex]
Step-by-step explanation:
7.
It is given that triangle (ABC) is similar to triangle (DEF). This means that triangle (DEF) is a scaled version of the triangle (ABC). Between these two triangles, there is a ratio. This ratio referred to as the ratio of similitude, is a factor that one multiplies a side of the triangle by, to get the length of the corresponding side in the other triangle. This number can be found by dividing the corresponding sides in the triangle.
As per the given picture, side (AB) corresponds to side (DE). Therefore divide side (AB) by (DE) to find the ratio of similitude,
[tex]\frac{AB}{DE}=\frac{10}{5}=2[/tex]
Multiply side (EF) by the ratio of similitude to find the length of its corresponding side (BC).
[tex]2(EF) = 2(11) = 22[/tex]
[tex]BC=22[/tex]
8.
The triangles (ABC) and (DEF) are similar. One can use the same logic applied to the last problem to solve this problem. For further reference, read the intro written to explain the process used to solve the problem (7).
One can see that sides (AB) and (DE) are corresponding sides, divide (DE) by (AB) to find the ratio of similitude;
[tex]\frac{DE}{AB}=\frac{4}{6}=\frac{2}{3}[/tex]
Now multiply this number by side (BC) to find the length of the corresponding side (EF);
[tex](BC)*\frac{2}{3}=EF\\12*\frac{2}{3}=EF\\8=EF[/tex]

Find the distance between the two points. Round to the nearest tenth if necessary. (0, 7), (–12, –2)
Answer:
Distance = 15 units
Step-by-step explanation:
[tex]Let \ (x_1 , y_ 1 ) = ( 0 , 7 ) \ , \ (x _ 2 , y _ 2 ) \ = ( -12 , -2 ) \\\\Dsitance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1 )^2} \\\\[/tex]
[tex]= \sqrt{(-12 - 0)^2 + ( -2 - 7)^2} \\\\=\sqrt{12^2 + 9^2 }\\\\=\sqrt{144 + 8 1} \\\\= \sqrt {225 } \\\\= 15[/tex]

Wally has a coupon to get 28% off a ticket to a Red Sox game. If the original price for his ticket is $160, how much will he pay for the ticket? Show/explain how you know!
Answer:
28% off 160.00 is 115.20
The difference is 44.80
Step-by-step explanation:
One way is to multiply 160 by 28 percent, and then divide the answer by one hundred, then deduct that result from the original price.
Purchase Price:
$160
Discount:
(160 x 28)/100 = $44.80
Final Price:
160 - 44.80 = $115.20
Thus, a product that normally costs $160 with a 28 percent discount will cost you $115.20, and you saved $44.80.
You can also calculate how much you save by simply moving the period in 28.00 percent two spaces to the left, and then multiply the result by $160 as follows: $160 x .28 = $44.80 savings.
Furthermore, you can get the final price by simply deducting .28 from 1 and multiplying it by $160 as follows: (1 - .28) x $160 = $115.20 final price.
Answer:
160-44.8=115.2
Step-by-step explanation:
160 would be 100%
28%=x
[tex]\frac{160}{x} = \frac{100}{28}[/tex]
[tex]\frac{x}{160} =\frac{28}{100}[/tex] x=44.8
28% of 160 would be 44.8
160-44.8=115.2

Hank is running sprints on a football field and likes to challenge himself, so instead of running straight down the field, he runs on the diagonal. Of the field is 50 yards wide and 100 yards long, how far does he run on the diagonal? Round your answer to the nearest yard.
Answer:
112 yards
Step-by-step explanation:
Applying Pythagoras theorem,
Pythagoras theorem states that, in a right angle triangle, the square of the hypotenuse is equal to the sum of the square of the two other sides.
Mathematically, it is expressed as
a² = b²+c²................. Equation 1
Where a = Length of the diagonal, b and c = lenght of the two other sides
From the question,
Given: b = 50 yards, c = 100 yards.
Substitute these values into equation 1
a² = 50²+100²
a² = 2500+10000
a² = 12500
a = √12500
a = 111.8
a = 112 yards

Given the equation of a circle below, determine the center and radius of the circle.
(x+5)^2+y^2=36
9514 1404 393
Answer:
center: (-5, 0)radius: 6Step-by-step explanation:
Compare the given equation to the standard form equation for a circle with center (h, k) and radius r.
(x -h)^2 +(y -k)^2 = r^2
You see that ...
-h = +5 ⇒ h = -5
-k = 0 ⇒ k = 0
r^2 = 36 ⇒ r = √36 = 6
The center is (h, k) = (-5, 0), and the radius is r = 6.
