To solve this problme you must apply the proccedure shown below:
1. To find the x-intercept y must be zero, so, you have:
<span>−75x − 4y = 7
y=0
</span><span>−75x=7
x=-7/75 (x-intercept)
2. To find the y-intecept x must be zero, then, yo have:
x=0
</span><span>−75x − 4y= 7
-4y=7
y=-7/4 (y-intercept)</span>
Answer:
1). Surface area of the prism = 112 cm²
2). Area of the sphere = 615.8 cm²
Step-by-step explanation:
1). Surface area of the triangular prism = Area of the triangular bases + Area of three lateral (rectangular) sides
Area of a triangular base =
=
= 10.5 cm²
Area of a rectangle = Length × width
Area of the rectangular lateral sides = (3 × 5) + (8 × 5) + (7 × 5)
= 15 + 40 + 35
= 90 cm²
Surface area of the prism = (2 × 10.5) + 90
= 21 + 90
= 112 cm²
2). Surface area of the sphere = 4πr²
= 4π(7)²
= 615.75
≈ 615.8 cm²
Over which interval(s) is the function decreasing?
Answer:
4h + 3
Step-by-step explanation:
- Any number times a variable will always be that number attached to the variable. When it says the product of 4 and h, it means 4 × h. 4 × h = 4h.
- Increased means added or become bigger. So, when it says 4h increased by 3, it means 4h + 3.
- Put them together: 4h + 3
I hope this helps!
Answer:
8. tenths
9. 90,000
Step-by-step:
tenths: ones are 10 times as small and move the decimal point one more time, tenths (note the ths)
90,000 the 9 in 295 is 90. 90*1000=90,000
