Answer:
5. x° = 38°; b° = 90°
6. m∠TSU = 110°
Step-by-step explanation:
The relationship relevant to these problems is that an inscribed angle is half the measure of the arc it intercepts. That is also true of the angle formed by a chord and a tangent.
__
5. Angle x° intercepts an arc marked 76°, so is half its measure: 76°/2 = 38°
x° = 38°
Arc b° is intercepted by an inscribed angle of 45°, so is twice that measure.
b° = 90°
__
6. Long arc SU is the remaining portion of the circle after short arc SVU is subtracted:
long arc SU = 360° -140° = 220°
Angle TSU is half that measure: 220°/2 = 110°.
m∠TSU = 110°

How does the graph of the function g(x)=7^x+5 differ from the graph of f(x)=7^x?
Answer:
see explanation
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Given g(x) = [tex]7^{x}[/tex] + 5
Then this is the graph of f(x) shifted vertically up by 5 units

Please help. Find the two missing sides and write your answer as in simplified radical form.
Answer:
x and y = 5√2.
Step-by-step explanation:
This is a 45:45:90 triangle so length of x = length of y.
In this triangle the ratio of the sides is 1:1:√2
Finding length of x and y:
1/√2 = x/10
√2x = 10
x = 10/√2
= 10√2/2
= 5√2.
Graph the line below:
y = -2x + 7
Answer:
Below.
Step-by-step explanation:
When x = 0, y = 7
and when y = 0, x = 3.5.
So plot the 2 points (0, 7) and (3.5, 0) on the grid and draw a straight line through these 2 points.
Connect these points [tex](\frac{7}{2} ,0)[/tex] and [tex](0, 7)[/tex] through a straight line. And this line represents [tex]y = -2x + 7[/tex].
How to graph a line?To graph a line we follow the following steps:
Find the y-intercept = b of the equation y = mx + b.Plot the y-intercept. The point will be (0, b).Plot the x intercept. The point will be (x, 0). Connect those two points with your line.According to the given question.
We have a equation of line
[tex]y = -2x+7[/tex]
The above equation of line is already in the slope intercept form.
So, the graph the line y = -2x + 7.
We first find the y intercept.
On comparing the above equation with y = mx + b, we get y = 7.
⇒ The point (0, 7) is our y intercept.
Therefore, we plot the y intercept or mark the point (0, 7) on graph.
Then we find the x intercept.
[tex]0 = -2x + 7[/tex] ( substitute y = 0)
⇒[tex]x = \frac{7 }{2}[/tex]
⇒ ([tex]\frac{7}{2}[/tex], 0 ) is our x intercept.
Connect these points [tex](\frac{7}{2} ,0)[/tex] and [tex](0, 7)[/tex] through a straight line. And this line represents [tex]y = -2x + 7[/tex].

The volume of a cone is 763.02 cubic inches. The radius and height of the cone are equal. What is the radius of the cone?
Answer:
The radius of the cone is 9cm
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cone
The volume of a cone is expressed as
V=1/3(πr²h)
We were told that the radius r and the height h are equal
I.e r=h
Substituting h=r in the formula we have
V= 1/3(πr²*r)
V =1/3(πr³)
To find the radius r let us substitute our given 763.02cm³ (note we assume unit in cm)
763.02= 1/3(3.142r³)
763.02= (3.142r³)/3
763.02*3=3.142r³
2289.06=3.142r³
r³=2289.06/3.142
r³= 728.54
r= ³√728.54
r= 8.99cm
≈r= 9cm

You want to make a retangular prism out of carboard. The base is 3 feet by 4 feet. The height is 2 feet. You have $5.00 and cardboard costs .10 per square foot. What is the surface area of the rectangular prism? How much will it cost to make teh retangular prosm out of cardboard?
Answer:
a) 24 square feet
b) $12
Step-by-step explanation:
You want to make a retangular prism out of cardboard. The base is 3 feet by 4 feet. The height is 2 feet. You have $5.00 and cardboard costs .10 per square foot.
a) What is the surface area of the rectangular prism?
Length × Width × Height
3 feet × 4 feet × 2 feet
= 24 square feet
b).How much will it cost to make the rectangular prism out of cardboard?
1 ft² = $0.5
24 ft² = x
Cross Multiply
x = 24ft² × $0.5/1 ft²
x = $12
It would cost $12 to make the rectangular prism out of the cardboard. You do not have sufficient money to make it
Leah needs to order some new supplies for the restaurant where she works. The restaurant needs at least 748 knives. There are currently 214 knives. If each set on sale contains 12 knives, write and solve an inequality which can be used to determine ss, the number of sets of knives Leah could buy for the restaurant to have enough knives.
Answer: s (greater than or equal to) 44.5
Step-by-step explanation:
current # of knives = 214
knives per set = 12
knives needed = 748
# of sets = s
knives per set x (times) # of sets + current # of knives (greater than or equal to) knives needed
12s + 214 (greater than or equal to) 748
SOLVE:
12s + 214 (greater than or equal to) 748
-214 -214
12s (greater than or equal to) 534 you need to divide both sides by 12
s (greater than or equal to) 44.5

Answer:
$3840
Step-by-step explanation:
10%= x/10 and the x is equal to 3840. 3840/10=384 now that I know what %10 of 3840 I can take off the discount price onto the original price, 3840-384=3456. So 3456 is the final price after including the 10% discount.

Which graph represents a function? On a coordinate plane, a line with 2 angles crosses the x-axis at (negative .5, 0), the y-axis at (0, 1), turns at (1, 3), crosses the x-axis at (1, 0), turns at (1, negative 2), and crosses the x-axis at (2, 0). On a coordinate plane, a curved line crosses the y-axis at (0, 1.5), the x-axis at (negative 2, 0), and the y-axis at (0, negative 1.5). On a coordinate plane, a line enters the plane at point (negative 5, 4), makes a 90-degree turn at (negative 1, 0), and leaves the plane at point (negative 5, negative 4). On a coordinate plane, a line with an s curve enters the plane at point (negative 3.75, 5), crosses the x-axis at (negative .75, 0), the y-axis at (0, 0), leaves x-axis at (.75, 0), and exits the plane at point (3.75, negative 5).
